Background and Aims: Glycoprotein (GP) IIb/IIIa inhibitors are recommended in acute myocardial infarction (AMI) for bailout treatment in case of angiographic microvascular obstruction (MVO), also termed no-reflow phenomenon, after percutaneous coronary intervention (PCI) with, however, lacking evidence (class IIa, level C)., Methods: The investigator-initiated, international, multicenter REVERSE-FLOW trial randomized 120 patients with AMI and Thrombolysis In Myocardial Infarction flow grade ≤2 after primary PCI to optimal medical therapy with or without GP IIb/IIIa inhibitor. The primary endpoint was infarct size (%LV) assessed by cardiac magnetic resonance (CMR). Secondary endpoints included CMR-derived MVO and 30-day adverse clinical events. The trial is registered with ClinicalTrials.gov: NCT02739711., Results: The population was predominantly male (76.7%) with a median age of 66 years and ST-elevation myocardial infarction in 73.3% of patients. Clinical and angiographic characteristics were well balanced between the cohorts. Patients in the treatment group (n=62) received eptifibatide (n=41) or tirofiban (n=21). Infarct size assessed by CMR imaging was similar in both study groups (25.4% of left ventricular mass [LV] vs. 25.2%LV; p=0.386). However, the number of patients with evidence of CMR-derived MVO (74.5% vs. 92.2%; p=0.017) and the extent of MVO (2.1%LV vs. 3.4%LV; p=0.025) were significantly reduced in the GP IIb/IIIa inhibitor group compared to controls. Thirty-day outcome showed an increased bleeding risk after GP IIb/IIIa inhibitor administration restricted to non-life-threatening bleedings (22.6% vs. 6.9%; p=0.016) without differences in all-cause mortality (4.8% vs. 3.4%; p=0.703)., Conclusions: Bailout GP IIb/IIIa inhibition in AMI patients with angiographic MVO failed to reduce the primary endpoint infarct size but decreased CMR-derived MVO and led to an increase in non-fatal bleeding events., (© The Author(s) 2024.

Objectives: Right heart catheterization (RHC) is a common diagnostic tool and of special importance in the diagnosis of pulmonary hypertension (PH). Until today, there have been no clear instructions or guidelines on which venous access to prefer. This meta-analysis assessed whether the choice of the venous access site for elective RHC has an impact on procedural or clinical outcomes., Methods: A structured literature search was performed. Single-arm reports and controlled trials reporting event data were eligible. The primary endpoint was a composite of access-related and overall complications., Results: Nineteen studies, including 6509 RHC procedures, were eligible. The results were analyzed in two groups. The first group compared central venous access (CVA; n = 2072) with peripheral venous access (PVA; n = 2680) and included only multi-arm studies (n = 12, C/P comparison). In the second group, all studies (n = 19, threeway comparison) were assessed to compare the three individual access ways. The overall complication rate was low at 1.0% (n = 68). The primary endpoint in the C/P comparison occurred significantly less for PVA than for CVA (0.1% vs. 1.2%; p = 0.004). In the threeway comparison, PVA had a significantly lower complication rate than femoral access (0.3% vs. 1.1%; p = 0.04). Jugular access had the numerically highest complication rate (2.0%), but the difference was not significant compared to peripheral (0.3%; p = 0.29) or femoral access (1.1%; p = 0.32)., Conclusion: This meta-analysis showed that PVA for RHC has a significantly lower complication rate than CVA. There was a low level of certainty and high heterogeneity. This pooled data analysis indicated PVA as the primary venous access for RHC., Competing Interests: Disclosures Florian Genske: no disclosures. Elias Rawish: no disclosures.

Background: Besides transcatheter edge-to-edge repair (TEER), there are new interventional treatment options for mitral and tricuspid regurgitation in evaluation, such as a complete replacement of the valve through a prosthesis., Case Summary: A 78-year-old previous coronary artery bypass graft-operated patient with symptomatic severe mitral regurgitation and tricuspid regurgitation was sequentially treated by a transfemoral transcatheter mitral and tricuspid valve prosthesis (Cardiovalve; Cardiovalve Ltd, Israel) due to unfavourable mitral valve anatomy. The transcatheter mitral valve implantation (TMVI) was performed first and after progression of the tricuspid regurgitation, a second transcatheter valve prosthesis was implanted in tricuspid position (TTVI) 1.5 years later. Imaging showed a twin look-alike picture of a mitral and tricuspid prosthesis and showing the possibility of a complete transcatheter based replacement of the mitral and tricuspid valve., Discussion: This case shows the possibility of a Cardiovalve prosthesis being used for TMVI and TTVI in a single patient. Especially in TEER ineligible patients, it might be a good treatment option after device approval., Competing Interests: Conflict of interest: T.S., C.F., and K.-H.K. received speaker honoraria and travel expenses from Cardiovalve., (© The Author(s) 2024.

Objectives: The association of pulmonary hypertension (PH) with the outcome after mitral transcatheter edge-to-edge repair (M-TEER) focusing on the new ESC/ERS guidelines definition for PH., Background: PH is frequently found in patients with mitral regurgitation and is associated with lower survival rates. Recent studies were based on echocardiographic parameters, but results based on invasive haemodynamics differentiating distinct types of PH using the new definition for PH are missing., Methods: 449 consecutive M-TEER-treated patients from December 2009 to February 2015 were included in this retrospective analysis. All patients were stratified by the distinct types of PH (no PH, precapillary PH, isolated postcapillary PH, combined post-PH and precapillary PH) according to the definitions of the ESC/ERS guidelines for the diagnosis of PH from 2015 (meanPA cut-off <25 mm Hg, pulmonary capillary wedge pressure (PCWP) cut-off ≤15 mm Hg, diastolic pulmonary gradient cut-off ≥7 mm Hg or pulmonary vascular resistance (PVR) >3 WU) and 2022 (meanPA cut-off ≤20 mm Hg, PCWP cut-off ≤15 mm Hg, PVR cut-off ≥3 WU)., Results: Patients with any type of PH (2015: meanPA cut-off 25 mm Hg; 2022: meanPA cut-off >20 mm Hg) showed a higher risk of death after M-TEER compared with patients with no PH (2015: HR 1.61 (95% CI 1.25 to 2.07); p<0.001 and 2022: HR 2.09 (95% CI 1.54 to 2.83); p<0.001). Based on the new PH definition, each PH subgroup showed a lower survival after M-TEER compared with patients with no PH. Echocardiographic estimated systolic PAP showed a correlation with invasively measured mean pulmonary artery pressure (mPAP) (r=0.29, p<0.001) and systolic pulmonary arterial pressure (r=0.34,p<0.001). Cox-regression analysis showed higher invasive diastolic, systolic and mean pulmonary pressures were associated with higher all-cause mortality (p<0.001). In addition, invasive measured higher right atrial pressure, lower pulmonary arterial compliance, higher PVR and higher wedge pressure were identified as predictors of all-cause mortality after M-TEER., Conclusions: The new PH definition discriminates PH groups and mortality better than the old definition. The lower threshold of mPAP of 20mmHg improved prognostication in this cohort of patients., Competing Interests: Competing interests: TU, BF, K-HK and SR declare the full disclosure of any relationship with industry.

Background: There is a lack of comparative data on transcatheter aortic valve implantation (TAVI) in degenerated surgical prostheses (valve-in-valve [ViV])., Aims: We sought to compare outcomes of using two self-expanding transcatheter heart valve (THV) systems for ViV., Methods: In this retrospective multicentre registry, we included consecutive patients undergoing transfemoral ViV using either the ACURATE neo/neo2 (ACURATE group) or the Evolut R/PRO/PRO+ (EVOLUT group). The primary outcome measure was technical success according to Valve Academic Research Consortium (VARC)-3. Secondary outcomes were 30-day all-cause mortality, device success (VARC-3), coronary obstruction (CO) requiring intervention, rates of severe prosthesis-patient mismatch (PPM), and aortic regurgitation (AR) ≥moderate. Comparisons were made after 1:1 propensity score matching., Results: The study cohort comprised 835 patients from 20 centres (ACURATE n=251; EVOLUT n=584). In the matched cohort (n=468), technical success (ACURATE 92.7% vs EVOLUT 88.9%; p=0.20) and device success (69.7% vs 73.9%; p=0.36) as well as 30-day mortality (2.8% vs 1.6%; p=0.392) were similar between the two groups. The mean gradients and rates of severe PPM, AR ≥moderate, or CO did not differ between the groups. Technical and device success were higher for the ACURATE platform among patients with a true inner diameter (ID) >19 mm, whereas a true ID ≤19 mm was associated with higher device success - but not technical success - among Evolut recipients., Conclusions: ViV TAVI using either ACURATE or Evolut THVs showed similar procedural outcomes. However, a true ID >19 mm was associated with higher device success among ACURATE recipients, whereas in patients with a true ID ≤19 mm, device success was higher when using Evolut.

Background: In patients not suitable for transfemoral transcatheter aortic valve implantation (TAVI), several access strategies can be chosen., Aim: To evaluate the use and patient outcomes of transaxillary (TAx), transapical (TA), and transaortic (TAo) as alternative access for TAVI in Germany; to further evaluate surgical cutdown vs. percutaneous TAx access., Methods: All patients entered the German Aortic Valve Registry (GARY) between 2011 and 2019 who underwent non-transfemoral TAVI were included in this analysis. Patients with TA, TAo, or TAx TAVI were compared using a weighted propensity score model. Furthermore, a subgroup analysis was performed for TAx regarding the percutaneous or surgical cutdown approach., Results: Overall, 9686 patients received a non-transfemoral access. A total of 8918 patients (92.1%) underwent TA, 398 (4.1%) TAo, and 370 (3.8%) TAx approaches. Within the TAx subgroup, 141 patients (38.1%) received subclavian cutdown, while 200 (54.1%) underwent a percutaneous approach. The TA patients had a significantly lower 30-day survival than TAx patients (TA 90.92% vs. TAx 95.59%, p = 0.006; TAo 92.22% vs. TAx 95.59%, p = 0.102). Comparing percutaneous and cutdown TAx approaches, no significant differences were seen. However, more vascular complications occurred (TA 1.8%, TAo 2.4%, TAx 12.2%; p < .001), and the hospital length of stay was shorter (TA 12.9 days, TAo 14.1 days, TAx 12 days; p < .001) after TAx access., Conclusion: It may be reasonable to consider TAx access first in patients not suitable for TF-TAVI, because the 30-day survival was higher compared with TA access and the 1-year survival was higher compared with TAo access. It remains important for the heart teams to offer alternative access modalities for patients not amenable to the standard TF-TAVI approaches., (© 2024. The Author(s).)

Background: Aortic valve (AV) repair is an evolving surgical strategy in the treatment of nonelderly adults with aortic regurgitation. We aimed to determine the 1-year outcome after AV repair vs surgical AV replacement (sAVR) using real-world data from the German Aortic Valve Registry., Methods: A total of 8076 aortic regurgitation patients (mean age, 59.1 ± 15.0 years; 76% men; mean The Society of Thoracic Surgeons score, 1.3 ± 1.1), who underwent AV surgical procedures between 2011 and 2015, were identified from German Aortic Valve Registry. The AV was repaired in 2327 patients (29%), and the remaining 5749 patients (71%) underwent sAVR. A weighted propensity score model, including the variables of age, sex, and The Society of Thoracic Surgeons score, was used to correct for baseline differences between AV repair and sAVR cohorts. The primary end point was 1-year survival after AV repair vs sAVR. Secondary end points were freedom from cardiac events and AV reinterventions., Results: Survival at 1 year was 97.7% (95% CI, 97.0%-98.5%) in the AV repair cohort vs 96.4% (95% CI, 95.9%-96.9%) in the propensity score-weighted sAVR cohort (log-rank P < .001). Cox regression revealed a significant advantage of AV repair vs sAVR (hazard ratio, 0.68; 95% CI, 0.51-0.90; P < .0001) on 1-year survival, which was independent of age. Cardiac event-free survival at 1 year was 85.7% (95% CI, 483.8%-87.7%) in the AV repair group vs 81.7% (95% CI, 80.7%-82.9%) in the sAVR group (log-rank P < .001). AV reintervention was required in 38 AV repair patients (1.6%) compared with 1.6% in the sAVR cohort (P = .59)., Conclusions: AV repair surgery, whenever intraoperatively feasible, is associated with a significantly better 1-year survival and 1-year cardiac event-free survival compared with sAVR., (Copyright © 2024 The Society of Thoracic Surgeons.

Background: Various second-generation transcatheter heart valve (THV) prostheses with high clinical efficacy and safety are available, but there is limited large-scale data available comparing their hemodynamic performance and clinical implications., Objective: To compare the hemodynamic performance and short-term clinical outcome of four second-generation THV prostheses., Methods: 24,124 patients out of the German Aortic Valve Registry who underwent transfemoral transcatheter aortic valve implantation (TAVI) (Evolut™ R n = 7028, Acurate neo™ n = 2922, Portico n = 878 and Sapien 3 n = 13,296) were included in this analysis. Propensity-score weighted analysis was performed to control for differences in age, left ventricular function, STS score and sex. Primary endpoint was survival at one-year, secondary endpoints were 30 days survival, pre-discharge transvalvular gradients, paravalvular leakage and peri-procedural complications., Results: Thirty-day and one-year survival were not significantly different between the four patient groups. Transvalvular gradients in Evolut™ R and Acurate neo™ were significantly lower as compared to Portico and Sapien 3 at hospital discharge. This difference exists across all annulus sizes. Paravalvular leakage ≥ II occurred significantly less often in the Sapien 3 group (1.2%, p < 0.0001). Rate of severe procedural complications was low and comparable in all groups. Permanent pacemaker implantation rate at one year was lowest in the ACUARATE neo group (13.0%) and highest in the Evolut™ R group (21.9%)., Conclusion: Albeit comparable short-term clinical outcomes there are certain differences regarding hemodynamic performance and permanent pacemaker implantation rate between currently available THV prostheses which should be considered for individual prosthesis selection., (© 2023.

Background: The exact incidence and predictors of new-onset atrial fibrillation (AF) after percutaneous closure of patent foramen ovale (PFO) are unknown., Objective: We sought to find post-procedural AF incidence rates and differences due to different screening strategies and devices., Methods: A systematic search was conducted in Cochrane, MEDLINE and EMBASE. Controlled trials fulfilling the inclusion criteria were included into this meta-analysis. The incidence of new-onset AF was the primary outcome. Further parameters were surveillance strategy, device type, AF treatment and neurological events. New AF was determined as early onset within one month after implantation and late thereafter., Results: 8 controlled trials and 16 cohort studies were eligible for quantitative analysis. 7643 patients received percutaneous PFO closure after cryptogenic stroke or transient ischaemic attack, 117 with other indications, whereas 1792 patients formed the control group. Meta-analysis of controlled trials showed an AF incidence of 5.1% in the interventional and 1.6% in the conservative arm, respectively (OR 3.17, 95% CI 1.46-6.86, P = 0.03, I 2  = 55%). 4.7% received high-quality surveillance strategy with Holter-ECG or Loop recorder whereby AF incidence was overall higher compared to the low-quality group with 12-lead ECG only (3.3-15% vs. 0.2-4.3%). Heterogeneous results on time of AF onset were found, limited by different follow-up strategies. CardioSEAL and Starflex seemed to have higher AF incidences in early and late onset with 4.5% and 4.2%, respectively., Conclusion: Percutaneous PFO closure led to higher AF post-procedural incidence compared to the conservative strategy. Heterogeneity in surveillance and follow-up strategy limited the generalizability., Trial Registration: Registered on PROSPERO (CRD42022359945)., (© 2023. The Author(s).)

Objective: After transcatheter aortic valve implantation (TAVI), the optimal regimen of anticoagulant therapy in patients with an additional indication for oral anticoagulation remains a matter of debate. This study investigates the efficacy of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in patients after TAVI in a real-world population., Methods: The German Aortic Valve RegistrY (GARY) is a prospective, multicentre registry enrolling patients undergoing invasive treatment for aortic valve disease. From January 2011 to December 2019, 1 41 790 patients from 92 hospitals in Germany were enrolled. Anticoagulatory treatment regimens were assessed at hospital discharge for patients after TAVI procedures. All-cause mortality and the combined endpoint 'cardiac and cerebrovascular events' containing myocardial infarction, stroke, transient ischaemic attack, aortic prosthesis reintervention and all-cause mortality in the first year after TAVI were examined by treatment regimen., Results: Of 45 598 patients (mean age 80.7±5.7 years, 49.3% males) undergoing TAVI, 16 974 patients (37.2%) received an anticoagulant regimen that included VKA or DOAC. Hereof, the majority of patients were prescribed VKA (n=11 333, 66.8%) compared with DOAC (n=5641, 33.2%) with an increase of DOAC use from 9.4% in 2011 to 69.9% in 2019. During the 1-year follow-up, the absolute event rates per 100 person-years for all-cause mortality and the combined endpoint cardiac and cerebrovascular events were 1.9 and 1.3 for VKA-treated and 1.7 and 1.2 for DOAC-treated patients, respectively. After adjustment for baseline confounders, all-cause mortality (HR 0.95, 95% CI 0.88 to 1.01, p=0.114) and cardiac and cerebrovascular event-free survival (HR 0.93, 95% CI 0.86 to 1.01, p=0.071) did not differ significantly between VKA and DOAC groups., Conclusions: This study supports evidence of the efficacy of DOAC use after TAVI in patients with an indication for oral anticoagulation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Tricuspid transcatheter edge-to-edge repair (T-TEER) for severe tricuspid regurgitation (TR) emerged as a novel treatment option for patients not amenable to surgery. However, knowledge regarding independent risk factors for a worse prognosis is rarely available. The study sought to investigate the impact of right ventricular cardiac power index (RVCPi) on 1-year outcomes in patients with severe symptomatic TR who underwent T-TEER. Consecutive patients with severe TR who underwent T-TEER from August 2020 to March 2022 were included and followed prospectively. Baseline clinical and invasive hemodynamic variables, changes in echocardiographic parameters and New York Heart Association functional class, and periprocedural and in-hospital major adverse events were assessed. Primary end point was defined as a composite of all-cause mortality and heart failure hospitalization at 1 year after T-TEER. A multivariable Cox proportional-hazards regression analysis was performed to identify independent risk factors for combined primary end point. RVCPi was calculated as: (cardiac index × mean pulmonary pressure) × K (conversion factor 2.22 × 10 -3 ) = W/m². Receiver operator characteristic analysis was used to determine discriminative capacity of RVCPi. The prognostic value of RVCPi threshold was tested using Kaplan-Meier analysis. In total, 102 patients (mean age 81 ± 6 years, 51% women) at high operative risk underwent T-TEER for severe TR. Primary end point occurred in 30 patients (32%). Receiver operator characteristic curve analysis demonstrated that RVCPi was associated with an area under the curve of 0.69 (95% confidence interval 0.56 to 0.82; p = 0.003). With a RVCPi threshold of 0.17 W/m² (maximally selected rank statistics), the event-free survival was significantly higher in the RVCPi <0.17 W/m² group compared with those with RVCPi ≥0.17 W/m² (71% vs 35%, log-rank p <0.001). In the multivariable Cox regression analysis, RVCPi was an independent predictor for the combined primary end point (hazard ratio 2.6, 95% confidence interval 1.4 to 5.1, p = 0.003). In conclusion, RVCPi is associated with outcome in patients who underwent T-TEER for severe TR and this hemodynamic predictor is useful in risk stratification of T-TEER candidates., Competing Interests: Declaration of Competing Interest Dr. Frerker received lecture honoraria and travel support from Abbott Vascular and Edwards Lifesciences.

Background: Takotsubo syndrome (TTS) is a reversible form of heart failure with incompletely understood pathophysiology., Objectives: This study analyzed altered cardiac hemodynamics during TTS to elucidate underlying disease mechanisms., Methods: Left ventricular (LV) pressure-volume loops were recorded in 24 consecutive patients with TTS and a control population of 20 participants without cardiovascular diseases., Results: TTS was associated with impaired LV contractility (end-systolic elastance 1.74 mm Hg/mL vs 2.35 mm Hg/mL [P = 0.024]; maximal rate of change in systolic pressure over time 1,533 mm Hg/s vs 1,763 mm Hg/s [P = 0.031]; end-systolic volume at a pressure of 150 mm Hg, 77.3 mL vs 46.4 mL [P = 0.002]); and a shortened systolic period (286 ms vs 343 ms [P < 0.001]). In response, the pressure-volume diagram was shifted rightward with significantly increased LV end-diastolic (P = 0.031) and end-systolic (P < 0.001) volumes, which preserved LV stroke volume (P = 0.370) despite a lower LV ejection fraction (P < 0.001). Diastolic function was characterized by prolonged active relaxation (relaxation constant 69.5 ms vs 45.9 ms [P < 0.001]; minimal rate of change in diastolic pressure -1,457 mm Hg/s vs -2,192 mm Hg/s [P < 0.001]), whereas diastolic stiffness (1/compliance) was not affected during TTS (end-diastolic volume at a pressure of 15 mm Hg, 96.7 mL vs 109.0 mL [P = 0.942]). Mechanical efficiency was significantly reduced in TTS (P < 0.001) considering reduced stroke work (P = 0.001), increased potential energy (P = 0.036), and a similar total pressure-volume area compared with that of control subjects (P = 0.357)., Conclusions: TTS is characterized by reduced cardiac contractility, a shortened systolic period, inefficient energetics, and prolonged active relaxation but unaltered diastolic passive stiffness. These findings may suggest decreased phosphorylation of myofilament proteins, which represents a potential therapeutic target in TTS.

Background: The need for permanent pacemaker (PPM) implantation is a common complication after transcatheter aortic valve replacement (TAVR). Deep implantation position is a risk factor for PPM implantation. Thus, in the field of self-expandable (SE) transcatheter heart valves (THV) cusp overlap projection (COP) technique was implemented to reduce parallax, allowing a more precise guidance of implantation depth., Aims: This meta-analysis aims to report the outcome of patients undergoing TAVR with SE THV using COP versus conventional implantation technique (CIT)., Methods: Systematical search in MEDLINE and EMBASE yielded five observational controlled studies comparing both implantation techniques for the SE Evolut prosthesis (Medtronic Intern. Ltd., CA, USA) and fulfilling the inclusion criteria for meta-analysis., Results: Totally, 1227 patients were included, comprising 641 who underwent COP and 586 CIT TAVR. Incidence of post-procedural need for PPM implantation was significantly lower in COP group (9.8% vs 20.6%; OR = 0.43; p < 0.00001). This was accompanied by significantly higher implantation position in COP group (mean difference distance from distal end of the intraventricular portion of the THV to the non-coronary cusp (NCC): - 1.03 mm; p = 0.00001). Incidence of new-onset left bundle branch block did not differ. Regarding procedural and 30-day mortality, technical success, post-procedural aortic regurgitation, and rates of multiple device implantation, no difference between COP and CIT was found., Conclusion: COP is an effective and safe implantation technique to reduce the need for a permanent pacemaker implantation during TAVR with SE Evolut prosthesis., (© 2023.

Aims: Identification of high-risk patients and individualized decision support based on objective criteria for rapid discharge after transcatheter aortic valve implantation (TAVI) are key requirements in the context of contemporary TAVI treatment. This study aimed to predict 30-day mortality following TAVI based on machine learning (ML) using data from the German Aortic Valve Registry., Methods and Results: Mortality risk was determined using a random forest ML model that was condensed in the newly developed TAVI Risk Machine (TRIM) scores, designed to represent clinically meaningful risk modelling before (TRIMpre) and in particular after (TRIMpost) TAVI. Algorithm was trained and cross-validated on data of 22 283 patients (729 died within 30 days post-TAVI) and generalisation was examined on data of 5864 patients (146 died). TRIMpost demonstrated significantly better performance than traditional scores [ C -statistics value, 0.79; 95% confidence interval (CI)] [0.74; 0.83] compared to Society of Thoracic Surgeons (STS) with C -statistics value 0.69; 95%-CI [0.65; 0.74]). An abridged (aTRIMpost) score comprising 25 features (calculated using a web interface) exhibited significantly higher performance than traditional scores ( C -statistics value, 0.74; 95%-CI [0.70; 0.78]). Validation on external data of 6693 patients (205 died within 30 days post-TAVI) of the Swiss TAVI Registry confirmed significantly better performance for the TRIMpost ( C -statistics value 0.75, 95%-CI [0.72; 0.79]) compared to STS ( C -statistics value 0.67, CI [0.63; 0.70])., Conclusion: TRIM scores demonstrate good performance for risk estimation before and after TAVI. Together with clinical judgement, they may support standardised and objective decision-making before and after TAVI., Competing Interests: Conflict of interest: T Friede reports personal fees for statistical consultancies (includingdata monitoring committees) from Novartis, Bayer, Janssen, Roche, Galapagos, Penumbra, Parexel, Vifor, BiosenseWebster, CSLBehring, Fresenius Kabi, Coherex Medical, LivaNova, Minoryx, IQVIA, Enanta, Relaxera, Immunic; all outside the submitted work.

Background: Residual mitral regurgitation (MR) is thought to be an important predictor of long-term survival following transcatheter edge-to-edge repair (TEER). Intraprocedural MR assessment using transesophageal echocardiography could be limited by image quality, hemodynamics, and patient sedation. The MitraScore is a validated multimodal approach for intraprocedural MR assessment during TEER., Objectives: This study aimed to assess the impact of residual MR using the MitraScore on 1-year mortality., Methods: Patients undergoing mitral TEER were eligible for inclusion in the prospective, multicenter MITRA-PRO registry (A Prospective Registry Study on 1-Year Mortality and the Prognostic Significance of MitraScore After MitraClip Implantation in Patients With Mitral Regurgitation). Patients with a MitraScore ≤3 were defined as patients with mild residual MR after mitral TEER, whereas a MitraScore ≥4 was considered as relevant residual MR. Mortality, rehospitalization, and major adverse events were assessed 1 year after TEER., Results: A MitraScore ≤3 was found in 1,059 patients (71.0%), whereas 432 patients revealed a MitraScore ≥4 (29.0%). One-year mortality was significantly lower in patients with nonrelevant residual MR (MitraScore ≤3 14.6% vs MitraScore≥4 22.1%). An almost linear relationship between intraprocedural MitraScore after TEER and mortality was observed. The combined clinical endpoint of mortality and rehospitalization within the 1-year follow-up was also significantly lower in the MitraScore ≤3 group (31.5%) than in the MitraScore ≥4 group (40.8%). A subgroup analysis confirmed the predictive value of the MitraScore in patients with primary, secondary, or mixed MR etiologies., Conclusions: Residual MR assessed by intraprocedural MitraScore after TEER predicts 1-year mortality and rehospitalization. Therefore, the multimodal MitraScore improves MR assessment during mitral TEER and might improve patient survival.(A Prospective Registry Study on 1-Year Mortality and the Prognostic Significance of MitraScore After MitraClip Implantation in Patients With Mitral Regurgitation [MITRA-PRO]; DRKS00012288)., Competing Interests: Funding Support and Author Disclosures This study was funded by Zentrum für klinische Studien (ZKS, Witten/Herdecke University), and core lab analysis was funded by Abbott Vascular.

Background: Data regarding the impact of the tricuspid valve gradient (TVG) after tricuspid transcatheter edge-to-edge repair (TEER) are scarce., Objectives: This study sought to evaluate the association between the mean TVG and clinical outcomes among patients who underwent tricuspid TEER for significant tricuspid regurgitation., Methods: Patients with significant tricuspid regurgitation who underwent tricuspid TEER within the TriValve (International Multisite Transcatheter Tricuspid Valve Therapies) registry were divided into quartiles based on the mean TVG at discharge. The primary endpoint was the composite of all-cause mortality and heart failure hospitalization. Outcomes were assessed up to the 1-year follow-up., Results: A total of 308 patients were included from 24 centers. Patients were divided into quartiles of the mean TVG as follows: quartile 1 (n = 77), 0.9 ± 0.3 mm Hg; quartile 2 (n = 115), 1.8 ± 0.3 mm Hg; quartile 3 (n = 65), 2.8 ± 0.3 mm Hg; and quartile 4 (n = 51), 4.7 ± 2.0 mm Hg. The baseline TVG and the number of implanted clips were associated with a higher post-TEER TVG. There was no significant difference across TVG quartiles in the 1-year composite endpoint (quartiles 1-4: 35%, 30%, 40%, and 34%, respectively; P = 0.60) or the proportion of patients in New York Heart Association class III to IV at the last follow-up (P = 0.63). The results were similar after adjustment for clinical and echocardiographic characteristics (composite endpoint quartile 4 vs quartile 1-quartile 3 adjusted HR: 1.05; 95% CI: 0.52-2.12; P = 0.88) or exploring post-TEER TVG as a continuous variable., Conclusions: In this retrospective analysis of the TriValve registry, an increased discharge TVG was not significantly associated with adverse outcomes after tricuspid TEER. These findings apply for the explored TVG range and up to the 1-year follow-up. Further investigations on higher gradients and longer follow-up are needed to better guide the intraprocedural decision-making process., Competing Interests: Funding Support and Author Disclosures Dr Coisne has served as a consultant for Abbott; and has received speaker fees from Abbott and GE Healthcare.

Aims: The impact of sexuality in patients with significant tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI) is unknown. The aim of this study was to investigate sex-specific outcomes in patients with significant TR treated with TTVI vs. medical therapy alone., Methods and Results: The Transcatheter Tricuspid Valve Therapies (TriValve) registry collected data on patients with significant TR from 24 centres who underwent TTVI from 2016 to 2021. A control cohort was formed by medically managed patients with ≥severe isolated TR diagnosed in 2015-18. The primary endpoint was freedom from all-cause mortality. Secondary endpoints were heart failure (HF) hospitalization, New York Heart Association (NYHA) functional status, and TR severity. One-year outcomes were assessed for the TriValve cohort and compared with the control cohort with the inverse probability of treatment weighting (IPTW). A total of 556 and 2072 patients were included from the TriValve and control groups, respectively. After TTVI, there was no difference between women and men in 1-year freedom from all-cause mortality 80.9% vs. 77.9%, P = 0.56, nor in HF hospitalization (P = 0.36), NYHA Functional Classes III and IV (P = 0.17), and TR severity >2+ at last follow-up (P = 0.42). Multivariable Cox-regression weighted by IPTW showed improved 1-year survival after TTVI compared with medical therapy alone in both women (adjusted hazard ratio 0.45, 95% confidence interval 0.23-0.83, P = 0.01) and men (adjusted hazard ratio 0.42, 95% confidence interval 0.18-0.89, P = 0.03)., Conclusion: After TTVI in high-risk patients, there were no sex-related differences in terms of survival, HF hospitalization, functional status, and TR reduction up to 1 year. The IPTW analysis shows a survival benefit of TTVI over medical therapy alone in both women and men., Competing Interests: Conflict of Interest: A.S. has served as a consultant and received consulting fees from NeoChord Inc.

Background: Patients with severe aortic stenosis (AS) frequently presented mitral regurgitation (MR), which may interfere with the standard echocardiographic measurements of mean pressure gradient (MPG), flow velocity, and aortic valve area (AVA)., Aims: Herein we investigated the prevalence and severity of MR in patients with severe AS and its role on the accuracy of the standard echocardiographic parameters of AS quantification., Methods: Of all patients with severe AS undergoing transcatheter or surgical aortic valve replacement enrolled in the German Aortic Registry from 2011 to 2017, 119,641 were included in this study. The population was divided based on the values of left ventricular ejection fraction ([LVEF] > 50%, LVEF 31-50%, and LVEF ≤ 30%] and AVA (0.80 to ≤ 1.00 cm 2 , 0.60 to < 0.80 cm 2 , 0.40 to < 0.60 cm 2 , and 0.20 to < 0.40 cm 2 )., Results: Overall, 77,890 (65%) patients with mild to-moderate and 4262 (4%) with severe MR were compared with 37,489 (31%) patients without MR. Patients with mild-to-moderate and severe MR presented significantly lower mPG (ΔmPG [95%CI] - 1.694 mmHg [- 2.123 to - 1.265], p < 0.0001 and - 6.954 mmHg [- 7.725 to - 6.183], p < 0.0001, respectively), that increased with LVEF impairment. Conversely, AVA did not differ (severe versus no MR: ΔAVA [95%CI]: - 0.007cm 2 [- 0.023 to 0.009], p = 0.973). Increasing MR severity was associated with significant mPG reduction throughout all AVA strata, causing a low-gradient pattern, that manifested since the early stages of severe AS (LVEF > 50%: AVA 0.80 to 1.00 cm 2 ; LVEF 31-50%: AVA 0.60 to 0.80 cm 2 )., Conclusions: In patients with severe AS, concomitant MR is common, contributes to the onset of a low-gradient AS pattern, and affects the diagnostic accuracy of flow-dependent AVA measurements. In this setting, a multimodality, AVA-centric approach should be implemented. In patients with severe aortic stenosis, concomitant mitral regurgitation contributes to the onset of a low-gradient pattern, warranting a multimodality, and AVA-centric diagnostic approach., (© 2022.

Objective: We compared TAVI vs. SAVR in patients with moderate-to-severe chronic kidney disease (eGFR 15-60 ml/min/1.73 m 2 ) for whom both procedures could possibly be considered (age ≤ 80 years, STS-score 4-8)., Background: According to both ACC/AHA and ESC/EACTS recent guidelines, aortic stenosis may be treated with either transcatheter (TAVI) or surgical (SAVR) aortic valve replacement in a subgroup of patients. A shared therapeutic decision is made by a heart team based on individual factors, including chronic kidney disease (CKD)., Methods: Data from the large nationwide German Aortic Valve Registry were used. A propensity score method was used to select 704 TAVI and 374 SAVR matched patients. Primary endpoint was 1-year survival. Secondary endpoints were clinical complications, including pacemaker implantation, vascular complications, myocardial infarction, bleeding, and the need for new-onset dialysis., Results: One-year survival was similar (HR [95% CI] for TAVI 1.271 [0.795, 2.031], p = 0.316), with no divergence in Kaplan-Meier curves. In spite of post-procedural short-term survival being numerically higher for TAVI patients and 1-year survival being numerically higher for SAVR patients, such differences did not reach statistical significance (96.4% vs. 94.2%, p = 0.199, and 86.2% vs. 81.2%, p = 0.316, respectively). In weighted analyses, pacemaker implantation, vascular complications, and were significantly more common with TAVI; whereas myocardial infarction, bleeding requiring transfusion, and longer ICU-stay and overall hospitalization were higher with SAVR. Temporary dialysis was more common with SAVR (p < 0.0001); however, a probable need for chronic dialysis was rare and similar in both groups., Conclusion: Both TAVI and SAVR led to comparable and excellent results in patients with moderate-to-severe CKD in an intermediate-risk population of patients with symptomatic severe aortic stenosis for whom both therapies could possibly be considered., (© 2022.

Background: Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery., Methods: TriCLASP is a prospective, single-arm, multicenter European post-market clinical follow-up study (NCT04614402) to evaluate the safety and performance of the PASCAL system (Edwards Lifesciences) in patients with severe or greater TR. At 30 days, a composite of major adverse events (MAEs) adjudicated by a clinical events committee, echocardiographic parameters adjudicated by core laboratory, and clinical, functional, and quality-of-life measures were evaluated., Results: Mean age of the 74 enrolled patients was 80.3 years, with 58.1% female, 90.5% systemic hypertension, and 77.0% in New York Heart Association (NYHA) class III/IV. Mean Society for Thoracic Surgeons score (MV repair) was 9.0%. TR severity was significantly reduced at discharge (p < 0.001) and sustained at 30 days (p < 0.001), and 90.0% of patients achieved ≤moderate TR. The composite MAE rate at 30 days was 3.0%, including 4 events in 2 patients: cardiovascular mortality 1.5%, stroke 1.5%, renal complications requiring unplanned dialysis or renal replacement therapy 1.5%, and severe bleeding 1.5%. There were no nonelective tricuspid valve reinterventions, major access site and vascular complications, major cardiac structural complications, or device embolizations. NYHA class I/II was achieved in 55.8%, 6-minute walk distance improved by 38.2 m (p < 0.001), and Kansas City cardiomyopathy questionnaire scores improved by 13.4 points (p < 0.001)., Conclusion: Experience with the PASCAL transcatheter valve repair system in a European post-market setting confirms favorable safety and effectiveness at 30 days. TR significantly reduced, and clinical, functional, and quality-of-life outcomes significantly improved. This study is ongoing. Clinical Trial Registration: The study is ongoing and registered on ClinicalTrials.gov as NCT04614402. The current analysis is an interim report., (© 2022 The Authors.

Background and Aims: Currently, it is unclear whether transcatheter aortic valve implantation (TAVI) without predilation (direct TAVI; d-TAVI) or with preimplantation balloon valvuloplasty (b-TAVI) provides similar clinical safety and efficacy. Therefore, we analyzed patients undergoing d-TAVI or b-TAVI for severe aortic stenosis (AS) with either self-expanding or balloon-expandable transcatheter heart valves (THVs) from the German Aortic Valve Registry (GARY)., Methods: Between 2011 and 2017, a total of 44,783 TAVI patients were collected, with 25,717 (57.4%) receiving a balloon-expandable THV and 19,066 (42.6%) receiving a self-expanding THV. A propensity-score weighted model was used to compare d-TAVI vs b-TAVI regarding differences in outcome., Results: B-TAVI was performed in 71% and d-TAVI was performed in 29% of patients. In the investigated time interval, frequency of b-TAVI declined from 88.4% to 58.2%, accompanied by a constant rate of postdilation. After propensity weighting of patients receiving balloon-expandable THV, d-TAVI vs b-TAVI was associated with more frequent postoperative transvalvular mean pressure gradients (mPG) >15 mm Hg (20.7% vs 18.4%; P<.001), similar rates of paravalvular leakage (PVL) ≥ moderate (18.0% vs 16.9%; P=.08), fewer postdilations (13.4% vs 15.5%; P<.001), and fewer complications (permanent pacemaker implantation, 10.2% vs 11.9% [P=.01]; vascular complications, 1.9% vs 2.6% [P<.01]; pericardial tamponade, 0.5% vs 0.9% [P<.01]; and stroke, 0.9% vs 1.3% [P=.02]). In patients receiving self-expanding THVs, d-TAVI vs b-TAVI was associated with more frequent postimplantation mean PG ≥ 15 mm Hg (12.7% vs 10.4%; P<.01), higher rates of PVL ≥ moderate (24.8% vs 16.5%; P<.001), and similar complication rates including permanent pacemaker implantation., Conclusions: The safety and efficacy of d-TAVI vs b-TAVI depends on the type of THV implanted. For balloon-expandable valves, d-TAVI provides an advantage, while self-expanding valves offer a similar safety profile for d-TAVI compared with b-TAVI. However, increased mPG post intervention with both valve types and more significant PVL in self-expanding THVs emphasize the importance of proper patient selection and evaluation of valve anatomy to identify suitable cases for d-TAVI.

Objectives: We aimed to develop and validate an effective prediction model for 1-year mortality risk in elective transfemoral transcatheter aortic valve replacement (TAVR), ie, the TAVR-Risk (TARI) model., Background: TAVR is the primary treatment for patients with symptomatic severe aortic valve stenosis; however, risk assessment tools for longer-term outcomes after TAVR remain scarce., Methods: This retrospective cohort study used logistic regression to test univariate and multivariate associations. The German Aortic Valve Registry (GARY) was the derivation (n = 20,704) and the Swedish SWEDEHEART TAVR Registry (SWENTRY) was the validation cohort (n = 3982). The main outcome was the area under the curve (AUC) in the prediction of 1-year mortality. The final model included 12 parameters that were associated with 1-year mortality in a multivariate analysis., Results: The TARI model (AUC, 0.66; 95% confidence interval [CI] 0.65-0.67) performed better as compared with the Society of Thoracic Surgeons (STS) score (AUC, 0.63; 95% CI, 0.62-0.64; P<.001) and logistic EuroSCORE I (AUC, 0.60; 95% CI, 0.59-0.61; P<.001) in the GARY derivation cohort, and discriminated the risk for 1-year mortality better than logistic EuroSCORE I in the SWENTRY validation cohort (AUC, 0.62; 95% CI, 0.60-0.64 vs AUC, 0.59; 95% CI, 0.57-0.61; P=.04)., Conclusions: This novel TARI score provides a relatively easy-to-use risk model and offers a superior prediction for 1-year mortality in European TAVR patients.

Background: Stroke remains a feared complication associated with transcatheter aortic valve implantation (TAVI). Embolic cerebral injury occurs in the majority of TAVI cases and can lead to cognitive dysfunction., Aims: The PROTEMBO C Trial evaluated the safety and performance of the ProtEmbo Cerebral Protection System in TAVI patients., Methods: Forty-one patients were enrolled in this single-arm study conducted at 8 European centres. The primary safety endpoint was the rate of VARC 2-defined major adverse cardiac and cerebrovascular events (MACCE) at 30 days; the primary performance endpoint was the composite rate of technical success versus performance goals (PG). Secondary endpoints included brain diffusion-weighted magnetic resonance imaging (DW-MRI), new lesion volume, and the rate of death or all strokes compared to historical data., Results: Thirty-seven of 41 enrolled patients underwent TAVI with the ProtEmbo device (intention-to-treat [ITT] population). Both primary endpoints were met. MACCE at 30 days was 8.1% (upper limit of the 95% confidence interval [CI]: 21.3% vs PG 25%; p=0.009), and technical success was 94.6% (lower limit of the 95% CI: 82.3% vs PG 75%; p=0.003). New DW-MRI lesion volumes with ProtEmbo were smaller than in historical data, and 87% of patients completing MRI follow-up had no single lesion >150 mm 3 . There was 1 stroke in a patient in whom the device was removed prematurely before TAVI completion., Conclusions: The PROTEMBO C Trial met its primary safety and performance endpoints compared to prespecified historical PGs. Patients had smaller brain lesion volumes on DW-MRI compared to prior series and no larger single lesions. These results warrant further evaluation of the ProtEmbo in a larger randomised controlled trial (RCT).

Objectives: Aortic valve (AV) repair is an evolving surgical strategy in the treatment of young patients with aortic regurgitation (AR) and/or aortic root aneurysm. We aimed to determine the clinical outcome following AV repair/AV-sparing root surgery using real-world data from the German Aortic Valve Registry., Methods: A total of 2327 patients with AR (mean age 55.2 ± 15.0 years, 76% men), who underwent AV repair/AV-sparing root surgery between 2011 and 2015 (i.e. 5% of 42 868 AV surgery patients enrolled in the German Aortic Valve Registry during the same period) were included. Study cohort was subdivided according to the technique of AV repair: isolated AV repair without root surgery (group I) (n = 914), AV-sparing root surgery (i.e. reimplantation or remodelling) without cusp repair (group II) (n = 1077) and AV-sparing root surgery (i.e. reimplantation or remodelling) with simultaneous cusp repair (group III) (n = 336). Primary end point was 1-year survival after AV repair/AV-sparing root surgery. Secondary end points were freedom from cardiac adverse events and freedom from AV reinterventions at 1-year follow-up., Results: Thirty-day mortality was 19 (0.8%) in the whole study cohort without significant differences in the 3 subgroups [4 (0.4%) patients in group I vs 14 (1.3%) patients in group II vs 1 (0.3%) patient in group III (P = 0.054)]. Postoperatively, 1445 (74%) patients had no residual AR, 474 (24%) patients had mild AR and 40 (2%) patients had moderate/severe AR at the time of hospital discharge. One-year survival (95% confidence interval) was 97.7% (97.1-98.3) in the whole study cohort and without significant difference among the 3 subgroups. One-year cardiac adverse event-free survival (95% confidence interval) was 85.7% (84.2-87.1) and was similar in all 3 study groups in propensity score-weighted analysis. A total of 38 (1.6%) patients required AV reintervention during a 1-year follow-up, without significant difference among subgroups (P = 0.11)., Conclusions: AV repair/AV-sparing root surgery is performed in 5% of patients requiring AV surgery in Germany. Our data demonstrate very satisfactory periprocedural and 1-year survival and cardiac event-free survival after AV repair surgery. Implementation of specific surgical techniques during the index procedure seems to result in comparable outcomes., (© The Author(s) 2022.

Objective: Periinterventional stroke is one of the most feared potential complication, among patients treated with transcatheter aortic valve implantation (TAVI). The purpose of this review was to investigate the incidence of cerebrovascular events and the influence of postinterventional neurologic check-up in patients undergoing TAVI., Methods: A systematic review and meta-analysis were conducted according to the PRISMA guideline. Three separate electronic searches of the public domains Medline and Clinicaltrials.gov were performed to identify the 30-day incidence of stroke within randomized controlled trials (RCTs) and registries for patients undergoing a TAVI procedure. A meta-analysis was conducted to evaluate the 30-day incidence of stroke within RCTs. Furthermore, we pooled the RCTs in which a scheduled neurological check-up was conducted or not to investigate the effect of this intervention., Results: Twenty-three studies including 399,491 TAVI patients were included, 6370 from RCTs, 833 from cerebral-embolic protection device RCTs and 392,288 were adopted from registries. The mean 30-day incidence of stroke among all reviewed studies was 2.33%. In RCTs evaluating TAVI the pooled stroke incidence was 3.86%, among RCTs focused CEP the incidence was 6.36% and in registries the incidence was 2.29%. Ten RCTs conducted scheduled neurological check-ups, the incidence in these was 4.03% and among the remaining RCTs it was 2.47%. In the meta-analysis, the pooled 30-day stroke incidence was 3.61% (95% CI 2.57-4.79%)., Conclusion: This systematic review demonstrates that the stroke incidences following TAVI differ strongly according to the study design and neurological follow-up. Intense neurological testing increases the incidence of a stroke after TAVI., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.)

Objectives: The aim of this study was to analyse the outcome of patients between 50 and 69 years of age undergoing biological or mechanical aortic valve replacement., Methods: Data were collected from the German Aortic Valve Registry. Data were analysed regarding baseline characteristics and outcome parameters such as 5-year survival, stroke and reintervention., Results: In total., 3046 patients undergoing isolated surgical aortic valve replacement between 2011 and 2012 were investigated and a propensity score matching was performed. Within this period, 2239 patients received a biological prostheses, while 807 patients received a mechanical prosthesis. Mean age in the biological group was 63.07 (±5.11) and 57.34 (±4.67) in the mechanical group (standardized mean difference 1.172). In the overall cohort, there were more female patients in the biological group (32.7% vs 28.4%) and log EuroSCORE I was higher (5.41% vs 4.26%). After propensity matching (610 pairs), there was no difference in the mortality at 5-year follow-up (12.1% biological vs 9.2% mechanical P = 0.05) nor for reoperation/reintervention (2.5% biological vs 2.0% mechanical, P = 0.546). Patients undergoing mechanical aortic valve replacement suffered from a higher stroke rate 3.3% vs 1.5% (P = 0.04) at 5-year follow-up., Conclusions: Aortic valve replacement with biological or mechanical prostheses showed similar 5-year outcomes for survival and reoperation in a propensity-matched cohort, but significantly increased stroke rate after mechanical aortic valve replacement. This could influence the choice of a mechanical valve in younger patients., (© The Author(s) 2022.

Background: In patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) and heart failure with severely reduced ejection fraction, prediction of postprocedural left ventricular ejection fraction (LVEF) improvement is challenging. Decision-making and timing for implantable cardioverter defibrillator (ICD) treatment are difficult and benefit is still unclear in this patient population., Objective: Aims of the study were to analyse long-term overall mortality in TAVI-patients with a preprocedural LVEF ≤ 35% regarding LVEF improvement and effect of ICD therapy., Methods and Results: Retrospective analysis of a high-risk TAVI-population suffering from severe AS and heart failure with a LVEF ≤ 35%. Out of 1485 TAVI-patients treated at this center between January 2013 and April 2018, 120 patients revealed a preprocedural LVEF ≤ 35% and had sufficient follow-up. 36.7% (44/120) of the patients suffered from persistent reduced LVEF without a postprocedural increase above 35% within 1 year after TAVI or before death, respectively. Overall mortality was neither significantly reduced by LVEF recovery above 35% (p = 0.31) nor by additional ICD treatment in patients with persistent LVEF ≤ 35% (p = 0.33)., Conclusion: In high-risk TAVI-patients suffering from heart failure with LVEF ≤ 35%, LVEF improvement to more than 35% did not reduce overall mortality. Patients with postprocedural persistent LVEF reduction did not seem to benefit from ICD treatment. Effects of LVEF improvement and ICD treatment on mortality are masked by the competing risk of death from relevant comorbidities., (© 2021. The Author(s).)

Background: The right ventricular (RV)-pulmonary arterial (PA) coupling ratio relates the efficiency with which RV stroke work is transferred into the PA. Lower ratios indicate an inadequate RV contractile response to increased afterload., Objectives: This study sought to evaluate the prognostic significance of RV-PA coupling in patients with tricuspid regurgitation (TR) who were undergoing transcatheter tricuspid valve repair or replacement (TTVR)., Methods: The study investigators calculated RV-PA coupling ratios for patients enrolled in the global TriValve registry by dividing the tricuspid annular plane systolic excursion (TAPSE) by the PA systolic pressure (PASP) from transthoracic echocardiograms performed before the procedure and 30 days after the procedure. The primary endpoint was all-cause mortality at 1-year follow-up., Results: Among 444 patients analyzed, their mean age was 76.9 ± 9.1 years, and 53.8% of the patients were female. The median TAPSE/PASP ratio was 0.406 mm/mm Hg (interquartile range: 0.308-0.567 mm/mm Hg). Sixty-three patients died within 1 year of TTVR, 21 with a TAPSE/PASP ratio >0.406 and 42 with a TAPSE/PASP ratio ≤0.406. In multivariable Cox regression analysis, a TAPSE/PASP ratio >0.406 vs ≤0.406 was associated with a decreased risk of all-cause mortality (HR: 0.57; 95% CI: 0.35-0.93; P = 0.023). In 234 (52.7%) patients with echocardiograms 30 days after TTVR, a decline in RV-PA coupling was independently associated with reduced odds of all-cause mortality (odds ratio [OR]: 0.42; 95% CI: 0.19-0.93; P = 0.032). The magnitude of TR reduction after TTVR (≥1+ vs <1+; OR: 2.53; 95% CI: 1.06-6.03; P = 0.037) was independently associated with a reduction in post-TTVR RV-PA coupling., Conclusions: RV-PA coupling is a powerful, independent predictor of all-cause mortality in patients with TR undergoing TTVR. These data suggest that the TAPSE/PASP ratio can inform patient selection and prognostication following TTVR., Competing Interests: Funding Support and Author Disclosures Dr Brener has received funding from a National Institute of Health grant (NHLBI-T32HL007343).

Patients presenting with severe aortic stenosis and large aortic annuli are challenging to treat because of the size limitations of available transcatheter heart valves. In this study, we aimed to determine clinical and hemodynamic outcomes in patients presenting with large aortic annuli who underwent transcatheter aortic valve implantation (TAVI). Patients from the German Aortic Valve Registry who underwent TAVI either with the Edwards Sapien (ES) or Medtronic CoreValve (MCV) systems from 2011 to 2017 were included. They were further stratified into a large (aortic annulus diameter 26 to 29 mm for ES; 26 to 30 mm for MCV) and extra-large (aortic annulus diameter >29 mm for ES; >30 mm for MCV) group and analyzed using propensity score adjustment. Extra-large was set beyond the sizing limitations according to the manufacturer's instructions for use. Patients in the large (n = 5,628) and extra-large (n = 509) groups were predominantly male (large: 92.6% vs extra-large: 91.9%). The 30-day mortality was comparable (large: 3.9% vs extra-large: 5.0%, p = 0.458). Procedure duration (large: 78.9 minutes ± 0.82 vs extra-large: 86.4 minutes ± 1.9, p <0.001) was longer in the extra-large group. Likewise, vascular complications (large: 6.2% vs extra-large: 12%, p = 0.002) and the need for a permanent pacemaker implantation (large: 18.8% vs extra-large: 26.0%, p = 0.027) were more often present in the extra-large group. Aortic regurgitation ≥II after valve implantation was numerically higher (large: 3.0% vs extra-large: 5.3%, p = 0.082) in patients with extra-large anatomy. In conclusion, patients with large and extra-large aortic annulus diameters who underwent TAVI have comparable 30-day mortality. Beyond the recommended annulus range, there is a higher risk for vascular complications and permanent pacemaker implantation., Competing Interests: Disclosures Drs.

Background: It is important to identify further predictors of outcome after successful transcatheter mitral valve repair (TMVR), as optimal patient selection remains difficult., Objective: The study investigates the prognostic benefit of the mean arterial pressure (MAP) to right atrial pressure (RAP) ratio (MAP/RAP ratio) after successful TMVR in patients with congestive heart failure (CHF) and severe mitral regurgitation (MR)., Method: Patients with CHF and severe MR were enrolled after successful TMVR (MR ≤ 2+ at discharge). The primary endpoint was a composite of all-cause mortality or hospitalisation for heart failure. The median follow-up time was 16 ± 9 months. Receiver Operating Characteristic (ROC) analysis was applied to assess the discriminatory power of the MAP/RAP ratio. The predictive value of the MAP/RAP ratio threshold was investigated using a Kaplan-Meier analysis. Multivariable logistic regression analysis was conducted to evaluate independent risk factors for the combined primary endpoint., Results: 145 patients (median age 76 [69-80 years], 60.3% male) were included. ROC curve analysis showed that MAP/RAP ratio was associated with an area under the curve of 0.62 (95% confidence interval (CI) 0.53-0.71; p = 0.01). A MAP/RAP ratio threshold of 7.13 was associated with 67.4% sensitivity and 57.0% specificity for the combined primary endpoint. Event-free survival was significantly lower in the MAP/RAP ratio < 7.13 group compared to those with MAP/RAP ratio ≥ 7.13 (62.2% versus 39.4%; log-rank p = 0.022). In logistic regression analysis MAP/RAP ratio was an independent predictor for the combined primary endpoint (odds ratio 0.75; 95% CI 0.62-0.90; p = 0.002)., Conclusions: The MAP/RAP ratio is associated with an unfavorable outcome in patients undergoing successful TMVR. Therefore, this new index could improve prognostic assessment of TMVR candidates., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Rico Osteresch received lecture honoraria from Abbott Vascular.

Objectives: To determine the 5-year outcome in patients treated by isolated transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (sAVR)-a prospective observational cohort study., Methods: A total of 18 010 patients were included (n = 8942 TAVI and n = 9068 sAVR) in the German Aortic Valve Registry (GARY) who were treated in 2011 and 2012 at 92 sites in central Germany. Eligible patients with TAVI and sAVR were matched using propensity scores in a nearest-neighbour approach. Patients with repeat procedures or unequivocal indication for one treatment option (e.g. frailty) were excluded (n = 4785 for TAVI and n = 2 for sAVR). This led to 13 223 patients (4157 TAVI and 9066 sAVR) as an unmatched subcohort. The main outcome measure was the 5-year all-cause mortality., Results: TAVI patients were significantly older (80.9 ± 6.1 vs 68.5 ± 11.1 years, P < 0.001), had a higher Society of Thoracic Surgeons (STS) score (6.3 ± 4.9 vs 2.6 ± 3.0, P < 0.001) and a higher 5-year all-cause mortality (49.8% vs 16.5%, P < 0.0001). There was no major difference in in-hospital stroke, in-hospital myocardial infarction, or temporary and chronic dialysis. In the propensity score-matched group (n = 3640), there were 763 deaths (41.9%) among 1820 TAVI patients compared with 552 (30.3%) among 1820 treated with sAVR during the 5-year follow-up (hazard ratio 1.51, 95% confidence interval 1.35-1.68; P < 0.0001). New pacemaker implantation was performed in 448 patients (24.6%) after TAVI and in 201 (11.0%) after sAVR (P < 0.0001)., Conclusions: The 5-year follow-up data show that TAVI patients were significantly older and had a higher STS score than sAVR patients. After propensity score matching, TAVI with early-generation prosthesis was associated with significantly higher 5-year all-cause mortality than sAVR., (© The Author(s) 2021.

Background:  Rapid deployment aortic valve replacement (RDAVR) and transcatheter aortic valve implantation (TAVI) have emerged as increasingly used alternatives to conventional aortic valve replacement to treat patients at higher surgical risk. Therefore, in this single-center study, we retrospectively compared clinical outcomes and hemodynamic performance of two self-expanding biological prostheses, the sutureless and rapid deployment valve (RDV) Perceval-S (PER) and the transcatheter heart valve (THV) ACURATE neo /TF (NEO) in a 1:1 propensity-score-matching (PSM) patient cohort., Methods:  A total of 332 consecutive patients with symptomatic aortic valve stenosis underwent either singular RDAVR with PER (119) or TAVI with NEO (213) at our institutions between 2012 and 2017. To compare the unequal patient groups, a 1:1 PSM for preoperative data and comorbidities was conducted. Afterward, 59 patient pairs were compared with regard to relevant hemodynamic parameter, relevant paravalvular leak (PVL), permanent postoperative pacemaker (PPM) implantation rate, and clinical postoperative outcomes., Results:  Postoperative clinical short-term outcomes presented with slightly higher rates for 30-day all-cause mortality (PER = 5.1% vs. NEO = 1.7%, p  = 0.619) and major adverse cardiocerebral event in PER due to cerebrovascular events (transient ischemic attack [TIA]-PER = 3.4% vs. TIA-NEO = 1.7%, p  = 0.496 and Stroke-PER = 1.7% vs. Stroke-NEO = 0.0%, p  = 1). Moreover, we show comparable PPM rates (PER = 10.2% vs. NEO = 8.5%, p  = 0.752). However, higher numbers of PVL (mild-PER = 0.0% vs. NEO = 55.9%, p  = 0.001; moderate or higher-PER = 0.0% vs. NEO = 6.8%, p  = 0.119) after TAVI with NEO were observed., Conclusion:  Both self-expanding bioprostheses, the RDV-PER and THV-NEO provide a feasible option in elderly and patients with elevated perioperative risk. However, the discussed PER collective showed more postoperative short-term complications with regard to 30-day all-cause mortality and cerebrovascular events, whereas the NEO showed higher rates of PVL., Competing Interests: None declared., (Thieme.

Background: Scarce data exist on patients with previous left valve surgery (PLVS) undergoing transcatheter tricuspid valve intervention (TTVI). This study sought to investigate the procedural and early outcomes in patients with PLVS undergoing TTVI., Methods: This was a subanalysis of the multicenter TriValve registry including 462 patients, 82 (18%) with PLVS. Data were analyzed according to the presence of PLVS in the overall cohort and in a propensity score-matched population including 51 and 115 patients with and without PLVS, respectively., Results: Patients with PLVS were younger (72 ± 10 vs 78 ± 9 years; p < 0.01) and more frequently female (67.1% vs 53.2%; P = 0.02). Similar rates of procedural success (PLVS 80.5%; no-PLVS 82.1%; P = 0.73), and 30-day mortality (PLVS 2.4%, no-PLVS 3.4%; P = 0.99) were observed. After matching, there were no significant differences in both all-cause rehospitalisation (PLVS 21.1%, no-PLVS 26.5%; P = 0.60) and all-cause mortality (PLVS 9.8%, no-PLVS 6.7%; P = 0.58). At last follow-up (median 6 [interquartile range 1-12] months after the procedure), most patients (81.8%) in the PLVS group were in NYHA functional class I-II (P = 0.12 vs no-PLVS group), and TR grade was ≤ 2 in 82.6% of patients (P = 0.096 vs no-PVLS group). A poorer right ventricular function and previous heart failure hospitalization determined increased risks of procedural failure and poorer outcomes at follow-up, respectively., Conclusions: In patients with PLVS, TTVI was associated with high rates of procedural success and low early mortality. However, about one-third of patients required rehospitalisation or died at midterm follow-up. These results would support TTVI as a reasonable alternative to redo surgery in patients with PLVS and suggest the importance of earlier treatment to improve clinical outcomes., (Copyright © 2021 Canadian Cardiovascular Society.

Purpose of Review: Transcatheter mitral valve replacement (TMVR) has been developed to address the need for an alternative therapeutic option to surgery in patients suffering from severe mitral regurgitation who are at high surgical risk. The present review illustrated the state-of-the-art of catheter-based mitral valve replacement evaluating technical characteristics and early clinical experience of different devices to outline prospects and challenges of TMVR., Recent Findings: Several devices are currently under clinical assessment. Early experience has demonstrated high procedural success of TMVR. However, TMVR faces several possible hurdles such as left ventricular outflow tract obstruction (LVOTO) after prosthesis deployment, access site complications, and thrombotic risk requiring anticoagulatory therapy. Future studies should assess long-term prosthesis stability, optimal anticoagulation regime, and occurrence of paravalvular leakage. The development of smaller TMVR prostheses suitable for transseptal implantation could overcome bleeding complications. In perspective, TMVR may emerge to a clinically relevant therapeutic approach for patients with severe MR at high surgical risk.

Objectives: Both balloon-expandable and self-expanding transcatheter aortic valves are used for transcatheter aortic valve implantation (TAVI). We compared procedural and clinical outcome variables of Sapien 3 and Evolut R/Pro in an all-comers collective., Methods: In this single-center registry, patients were consecutively treated with the Sapien 3 from November 2014 to March 2017 (n = 129) and from April 2017 to December 2018 mainly (>95%) with the Evolut R/Pro (n = 124), due to a switch in the main TAVI supplier driven by hospital management. Data were retrospectively analyzed before and after the switch., Results: One-year follow-up data were available for 122 (94%) of the Sapien and 112 (90%) of the Evolut patients. Baseline characteristics were comparable (EuroSCORE: Sapien 21.8 ± 0.9% vs Evolut 22.5 ± 0.8%; P=.20). Evolut implantation was associated with a higher radiation dose (Sapien 35770 ± 2345 mGy•cm² vs Evolut 85072 ± 8202 mGy•cm²; P<.001), more postimplantation balloon dilations (Sapien 17.1% vs Evolut 37.1%; P<.001), but similar procedure time (Sapien 75.2 ± 3.8 min vs Evolut 74.6 ± 3 min; P=.30). In-hospital mortality (Sapien 3.1% vs Evolut 4.0%; P=.70), all-cause mortality (Sapien 13.2% vs Evolut 15.3%; P=.70), all-stroke rate (Sapien 1.5% vs Evolut 6.5%; P=.05), and pacemaker implantation rate (Sapien 13.2% vs Evolut 18.5%; P=.30) were similar at 1 year. Permanent pacemaker rate was numerically higher in the first 6 months with Evolut (<6 months 26.7% vs >6 months 16%; P=.62); furthermore, radiation dose and balloon dilations also suggest a learning curve with Evolut., Conclusions: Switching from Sapien 3 to Evolut R/Pro was not associated with a difference regarding periprocedural or 1-year clinical outcomes.

Background: In recent studies, a 5-stage cardiac damage classification in severe aortic stenosis (AS) based on echocardiographic parameters has shown to provide predictive value regarding clinical outcome. The objective of this study was to investigate the prognostic impact of a cardiac damage classification based on invasive hemodynamics in patients with AS undergoing transcatheter aortic valve replacement (TAVR)., Methods: A total of 1400 patients with symptomatic AS and full invasive hemodynamic assessment before TAVR were included. Patients were categorized according to their cardiac damage stage into five groups that are defined as: stage 0, no cardiac damage; stage 1, left ventricular damage; stage 2, left atrial and/or mitral valve damage; stage 3, pulmonary vasculature and/or tricuspid valve damage; stage 4, right ventricular damage., Results: 9.9% patients were classified as stage 0, 23.6% as stage 1, the majority of patients as stage 2 (33.5%), 23.1% as stage 3 and 10% as stage 4. One- and 4-year mortality were 10.1%/29.5% in stage 0, 16.1%/60.6% in stage 1, 17.3%/39.4% in stage 2, 22%/54.6% in stage 3, 27.1%/62.2% in stage 4 (p = 0.001/p < 0.001). The extent of cardiac damage was independently associated with increased mortality after TAVR (HR 1.16 per each increment in stage, 95% confidence interval 1.03-1.18; p = 0.018)., Conclusions: Cardiac damage staging in severe AS patients based on invasive hemodynamics appears to show strong association between the extent of cardiac damage and post-TAVR mortality. This staging classification provides predictive value and may improve risk stratification, therapy management and decision-making in patients with AS. Invasive Staging Classification of Cardiac Damage in Severe Symptomatic Aortic Stenosis has an Impact on Outcome after TAVR. (Top) Invasive staging criteria for cardiac damage in five stages using left ventricular end-diastolic pressure (LVEDP) for stage 1 (red), post-capillary wedge pressure (PCWP) for stage 2 (green), systolic pulmonary artery pressure (SPAP) for stage 3 (purple) and right atrial pressure (RAP) for stage 4 (yellow). The cake chart shows the distribution of the different stage in the whole cohort. (Bottom) Survival Analyses According to Stage of Cardiac Damage after Transcatheter Aortic Valve Replacement using Invasive Criteria. Kaplan-Meier plots comparing overall (left) and cardiovascular (right) 4-year survival showing with the more advancing stage a higher mortality rate.

Objectives: Chronic kidney disease (CKD) is a key risk factor in patients undergoing transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). We analysed the impact of estimated glomerular filtration rate (eGFR) and CKD stages on their mid-term survival., Methods: Data from 29 893 patients enrolled in the German Aortic Valve registry from January 2011 to December 2015 receiving TAVI (n = 12 834) or SAVR (n = 17 059) at 88 sites were included. The impact of renal impairment, as measured by eGFR and CKD stages, was investigated. The primary end-point was 1-year cumulative all-cause mortality., Results: Higher CKD stages were significantly associated to lower in-hospital, 30-day- and 1-year survival rates. Both TAVI- and SAVR-treated patients in CKD 3a, 3b, 4 and 5 stages showed significant and gradually increasing HR values for 1-year all-cause mortality. The same trend persisted in multivariable analysis, although HR values for CKD 3a and 5 did not reach significance in TAVI patients, whereas CKD 4 + 5 did not reach statistical significance in SAVR. Likewise, eGFR as a continuous variable was a significant predictor for 1-year mortality, with the best cut-off points being 47.4 ml/min/1.73 m2 for TAVI and 59.8 ml/min/1.73 m2 for SAVR. Significant 8.6% and 9.0% increases in 1-year mortality were observed for every 5-ml reduction in eGFR for TAVI and SAVR, respectively., Conclusions: CKD ≥3b and CKD ≥3a are the independent major risk factors for mortality in patients undergoing TAVI and SAVR, respectively. In the overall population of patients with severe aortic stenosis, an appropriate stratification based on CKD substage may contribute to a better selection of patients suitable for such therapies., (© The Author(s) 2021.

Background Recurrence of mitral regurgitation (MR) after surgical mitral valve repair (SMVR) varies and may require reoperation. Redo mitral valve surgery can be technically challenging and is associated with increased risk of mortality and morbidity. We aimed to assess the feasibility and safety of MitraClip as a treatment strategy after failed SMVR and identify procedure modifications to overcome technical challenges. Methods and Results This international multicenter observational retrospective study collected information for all patients from 16 high-volume hospitals who were treated with MitraClip after failed SMVR from October 29, 2009, until August 1, 2017. Data were anonymously collected. Technical and device success were recorded per modified Mitral Valve Academic Research Consortium criteria. Overall, 104 consecutive patients were included. Median Society of Thoracic Surgeons score was 4.5% and median age was 73 years. At baseline, the majority of patients (82%) were in New York Heart Association class ≥III and MR was moderate or higher in 86% of patients. The cause of MR pre-SMVR was degenerative in 50%, functional in 35%, mixed in 8%, and missing/unknown in 8% of patients. The median time between SMVR and MitraClip was 5.3 (1.9-9.7) years. Technical and device success were 90% and 89%, respectively. Additional/modified imaging was applied in 21% of cases. An MR reduction of ≥1 grade was achieved in 94% of patients and residual MR was moderate or less in 90% of patients. In-hospital all-cause mortality was 2%, and 86% of patients were in New York Heart Association class ≤II. Conclusions MitraClip is a safe and less invasive treatment option for patients with recurrent MR after failed SMVR. Additional/modified imaging may help overcome technical challenges during leaflet grasping.

Background During the past decade, the use of transcatheter aortic valve replacement (TAVR) was extended beyond treatment-naïve patients and implemented for treatment of degenerated surgical bioprosthetic valves. Selection criteria for either valve-in-valve (viv) TAVR or redo surgical aortic valve replacement are not well established, and decision making on the operative approach still remains challenging for the interdisciplinary heart team. Methods and Results This review was intended to analyze all studies on viv-TAVR focusing on short- and mid-term stroke and mortality rates compared with redo surgical aortic valve replacement or native TAVR procedures. A structured literature search and review process led to 1667 potentially relevant studies on July 1, 2020. Finally, 23 studies fulfilled the inclusion criteria for qualitative analysis. All references were case series either with or without propensity score matching and registry analyses. Quantitative synthesis of data from 8509 patients revealed that viv-TAVR is associated with mean 30-day stroke and mortality rates of 2.2% and 4.2%, respectively. Pooled data analysis showed no significant differences in 30-day stroke rate, 30-day mortality, and 1-year mortality between viv-TAVR and comparator treatment (native TAVR [n=11 804 patients] or redo surgical aortic valve replacement [n=498 patients]). Conclusions This review is the first one comparing the risk for stroke and mortality rates in viv-TAVR procedures with native TAVR approach and contributes substantial data for the clinical routine. Moreover, this systematic review is the most comprehensive analysis on ischemic cerebrovascular events and early mortality in patients undergoing viv-TAVR. In this era with increasing numbers of bioprosthetic valves used in younger patients, viv-TAVR is a suitable option for the treatment of degenerated bioprostheses.
