Background: Mitral valve transcatheter edge-to-edge repair (M-TEER) reduces secondary mitral regurgitation (MR) in heart failure and impacts survival in selected patients as demonstrated in the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial. However, long-term outcome data after M-TEER under real-world conditions are lacking., Objectives: This study sought to assess long-term efficacy and survival after M-TEER in a large real-world registry., Methods: We analyzed patients with significant secondary MR undergoing M-TEER from the EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) registry. Long-term MR reduction, functional outcomes, survival rate, and predictors for all-cause mortality were assessed., Results: In this study, 1,628 patients undergoing M-TEER (mean age 73.8 years, mean EuroSCORE II [European System for Cardiac Operative Risk Evaluation II] 6.9%, 86.6% NYHA functional class ≥III) with available long-term data were included. Five-year survival was 35.0%. Long-term MR reduction (MR grade ≤2+: baseline 4.1%, discharge 92.2%, 5-year follow-up 85.5%; P < 0.001) and functional improvement (NYHA ≤II: baseline 13.4%, 5-year follow-up 60.1%; P < 0.001) was observed. The degree of residual MR was associated with 5-year survival (residual MR grade ≤1+: 38.6%; 2+: 30.5%; ≥3+: 22.6%; P < 0.001). Independent predictors for 5-year all-cause mortality post-M-TEER included age, renal function, residual MR, NYHA functional class, left ventricular ejection-fraction, and COAPT trial eligibility (P < 0.01 for all)., Conclusions: This extensive multicenter registry underscores the long-term efficacy of M-TEER in real-world clinical practice and identifies predictors for long-term survival.

Background: The impact of intraprocedural results following transcatheter edge-to-edge repair (TEER) in primary mitral regurgitation (MR) is controversial., Objectives: This study sought to investigate the prognostic impact of intraprocedural residual mitral regurgitation (rMR) and mean mitral valve gradient (MPG) in patients with primary MR undergoing TEER., Methods: The PRIME-MR (Outcomes of Patients Treated With Mitral Transcatheter Edge-to-Edge Repair for Primary Mitral Regurgitation) registry included consecutive patients with primary MR undergoing TEER from 2008 to 2022 at 27 international sites. Clinical outcomes were assessed according to intraprocedural rMR and mean MPG. Patients were categorized according to rMR (optimal result: ≤1+, suboptimal result: ≥2+) and MPG (low gradient: ≤5 mm Hg, high gradient: > 5 mm Hg). The prognostic impact of rMR and MPG was evaluated in a Cox regression analysis. The primary endpoint was 2-year all-cause mortality or heart failure hospitalization., Results: Intraprocedural rMR and mean MPG were available in 1,509 patients (median age = 82 years [Q1-Q3: 76.0-86.0 years], 55.1% male). Kaplan-Meier analysis according to rMR severity showed significant differences for the primary endpoint between rMR ≤1+ (29.1%), 2+ (41.7%), and ≥3+ (58.0%; P < 0.001), whereas there was no difference between patients with a low (32.4%) and high gradient (42.1%; P = 0.12). An optimal result/low gradient was achieved in most patients (n = 1,039). The worst outcomes were observed in patients with a suboptimal result/high gradient. After adjustment, rMR ≥2+ was independently linked to the primary endpoint (HR: 1.87; 95% CI: 1.32-2.65; P < 0.001), whereas MPG >5 mm Hg was not (HR: 0.78; 95% CI: 0.47-1.31; P = 0.35)., Conclusions: Intraprocedural rMR but not MPG independently predicted clinical outcomes following TEER for primary MR. When performing TEER in primary MR, optimal MR reduction seems to outweigh the impact of high transvalvular gradients., Competing Interests: Funding Support and Author Disclosures Dr Ludwig has received travel compensation from Edwards Lifesciences; has received speaker honoraria from Abbott; has received advisory fees from Bayer; and is a consultant for New Valve Technology.

Background: Right ventricular impairment is common among patients undergoing transcatheter edge-to-edge repair for secondary mitral regurgitation (SMR). Adherence to guideline-directed medical therapy (GDMT) for heart failure is poor in these patients., Objectives: The aim of this study was to evaluate the impact of GDMT on long-term survival in this patient cohort., Methods: Within the EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) international registry, we selected patients with SMR and right ventricular impairment (tricuspid annular plane systolic excursion ≤17 mm and/or echocardiographic right ventricular-to-pulmonary artery coupling <0.40 mm/mm Hg). Titrated guideline-directed medical therapy (GDMT tit ) was defined as a coprescription of 3 drug classes with at least one-half of the target dose at the latest follow-up. The primary outcome was all-cause mortality at 6 years., Results: Among 1,213 patients with SMR and right ventricular impairment, 852 had complete data on medical therapy. The 123 patients who were on GDMT tit showed a significantly higher long-term survival vs the 729 patients not on GDMT tit (61.8% vs 36.0%; P < 0.00001). Propensity score-matched analysis confirmed a significant association between GDMT tit and higher survival (61.0% vs 43.1%; P = 0.018). GDMT tit was an independent predictor of all-cause mortality (HR: 0.61; 95% CI: 0.39-0.93; P = 0.02 for patients on GDMT tit vs those not on GDMT tit ). Its association with better outcomes was confirmed among all subgroups analyzed., Conclusions: In patients with right ventricular impairment undergoing transcatheter edge-to-edge repair for SMR, titration of GDMT to at least one-half of the target dose is associated with a 40% lower risk of all-cause death up to 6 years and should be pursued independent of comorbidities., Competing Interests: Funding Support and Author Disclosures Dr Pfister is a consultant for Edwards Lifesciences; and has received speaker honoraria from Edwards Lifesciences and Abbott Vascular.

Aims: Achieving optimized guideline-directed medical therapy (GDMT) is recommended prior to transcatheter mitral valve edge-to-edge repair (M-TEER) for secondary mitral regurgitation (SMR). We aimed to propose and validate an easy-to-use score for assessing the quality of GDMT in patients with heart failure with reduced ejection fraction (HFrEF) undergoing M-TEER., Methods and Results: Among the 1641 EuroSMR patients enrolled in the EuroSMR Registry who underwent M-TEER, a total of 1072 patients [median age 74, interquartile range (IQR) 67-79 years, 29% female] had complete data on GDMT and a left ventricular ejection fraction ≤ 40% and were included in the current study. We proposed a GDMT score that considers the dosage levels of three medication classes (angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists), with a maximum score of 12 points indicating optimal GDMT. The primary outcome was all-cause mortality. The median GDMT score was 4 points (IQR 3-6). All three domains of the scoring system were associated with all-cause mortality (P < 0.05 for all). The overall GDMT score was associated with all-cause mortality (hazard ratio 0.90, 95% confidence interval 0.86-0.95 for each 1-point increase in the GDMT score). This association remained significant after adjusting for renal function and co-morbidities., Conclusions: This study demonstrates the utility of a simple GDMT scoring system for assessing the adequacy of GDMT in HFrEF patients with relevant SMR undergoing M-TEER. The GDMT score has potential applications in guiding the design of future clinical trials and aiding clinical decision-making processes., (© 2024 The Authors.

Introduction and Objectives: Concerns surrounding the consequences of ionizing radiation (IR) have increased in interventional cardiology (IC). Despite this, the ever-growing complexity of diseases as well as procedures can lead to greater exposure to radiation. The aim of this survey, led by Portuguese Association of Interventional Cardiology (APIC), was to evaluate the level of awareness and current practices on IR protection among its members., Methods: An online survey was emailed to all APIC members, between August and November 2021. The questionnaire consisted of 50 questions focusing on knowledge and measures of IR protection in the catheterization laboratory. Results were analyzed using descriptive statistics., Results: From a response rate of 46.9%, the study obtained a total sample of 159 responses (156 selected for analysis). Most survey respondents (66.0%) were unaware of the radiation exposure category, and only 60.4% reported systematically using a dosimeter. A large majority (90.4%) employed techniques to minimize exposure to radiation. All participants used personal protective equipment, despite eyewear protection only being used frequently by 49.2% of main operators. Ceiling suspended shields and table protectors were often used. Only two-thirds were familiar with the legally established limit on radiation doses for workers or the dose that should trigger patient follow-up. Most of the survey respondents had a non-certified training in IR procedures and only 32.0% had attended their yearly occupational health consultation., Conclusions: Safety methods and protective equipment are largely adopted among interventional cardiologists, who have shown some IR awareness. Despite this, there is room for improvement, especially concerning the use of eyewear protection, monitoring, and certification., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

Introduction and Objective: Coronary artery disease is highly prevalent among patients with severe aortic stenosis who undergo transcatheter aortic valve replacement (TAVR). As indications for TAVR are now expanding to younger and lower-risk patients, the need for coronary angiography (CA) and percutaneous coronary intervention (PCI) during their lifetime is expected to increase. The objective of our study was to assess the need for CA and the feasibility of re-engaging the coronary ostia after TAVR., Methods: We performed a retrospective analysis of 853 consecutive patients undergoing TAVR between August 2007 and December 2020. Patients who needed CA after TAVR were selected. The primary endpoint was the rate of successful coronary ostia cannulation after TAVR., Results: Of a total of 31 CAs in 28 patients (3.5% of 810 patients analyzed: 57% male, age 77.8±7.0 years) performed after TAVR, 28 (90%) met the primary endpoint and in three cannulation was semi-selective. All failed selective coronary ostia cannulations occurred in patients with a self-expanding valve. Sixteen (52%) also had indication for PCI, which was successfully performed in all. The main indication for CA was non-ST-elevation acute coronary syndrome (35%, n=11). Two cases of primary PCI occurred without delay. There were no complications reported during or after the procedure., Conclusion: Although CA was rarely needed in patients after TAVR, selective diagnostic CA was possible in the overwhelming majority of patients. PCI was performed successfully in all cases, without complications., (Copyright © 2023 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: Current rates of permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation (TAVI) range between 3.4% and 25.9%. PPMI is associated with a worse prognosis. A lower valve implantation depth is associated with an increased risk of conduction disturbances. Theoretically, cusp-overlap projection (COP) has the potential to enable higher valve deployment., Objective: To compare the 30-day PPMI incidence post-TAVI using self-expanding valves according to the fluoroscopic guidance technique., Methods: This retrospective single-center study assessed consecutive patients undergoing TAVI with CoreValve™ valves between April 2019 and November 2021, grouped according to the fluoroscopic guidance technique (COP vs. coplanar implantation technique [CIT])., Results: A total of 122 patients were included, predominantly women (52.5%), with a mean age of 81.6±5.5 years. COP was used in 49.2% of the sample. The CIT group had a significantly higher prevalence of previous beta-blocker use (p<0.01), lower baseline left ventricular ejection fraction (p=0.04) and a higher EuroSCORE II (p=0.02). The 30-day PPMI rate was 27.9% (n=34), with no significant difference between the COP and CIT groups (26.7% vs. 29.0%, p=0.77). Complete atrioventricular block was the main cause (38.5%). Likewise, mean fluoroscopy time (p=0.14) and contrast volume (p=0.35) used were similar between the two groups. Radiation dose was lower in the COP group (p=0.02). There was no significant difference between post-TAVI grades III and IV aortic valve regurgitation (p=0.27) and there were no cases of periprocedural acute coronary occlusion., Conclusions: This study shows that the COP technique, although safe and not associated with increased complexity, did not significantly reduce the 30-day PPMI rate compared to the traditional CIT view., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

Background: Guideline-directed medical therapy (GDMT) optimization is mandatory before transcatheter edge-to-edge mitral valve repair (M-TEER) in patients with secondary mitral regurgitation (SMR) and heart failure (HF) with reduced ejection fraction (HFrEF). However, the effect of M-TEER on GDMT is unknown., Objectives: The authors sought to evaluate frequency, prognostic implications and predictors of GDMT uptitration after M-TEER in patients with SMR and HFrEF., Methods: This is a retrospective analysis of prospectively collected data from the EuroSMR Registry. The primary events were all-cause death and the composite of all-cause death or HF hospitalization., Results: Among the 1,641 EuroSMR patients, 810 had full datasets regarding GDMT and were included in this study. GDMT uptitration occurred in 307 patients (38%) after M-TEER. Proportion of patients receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists was 78%, 89%, and 62% before M-TEER and 84%, 91%, and 66% 6 months after M-TEER (all P < 0.001). Patients with GDMT uptitration had a lower risk of all-cause death (adjusted HR: 0.62; 95% CI: 0.41-0.93; P = 0.020) and of all-cause death or HF hospitalization (adjusted HR: 0.54; 95% CI: 0.38-0.76; P < 0.001) compared with those without. Degree of MR reduction between baseline and 6-month follow-up was an independent predictor of GDMT uptitration after M-TEER (adjusted OR: 1.71; 95% CI: 1.08-2.71; P = 0.022)., Conclusions: GDMT uptitration after M-TEER occurred in a considerable proportion of patients with SMR and HFrEF and is independently associated with lower rates for mortality and HF hospitalizations. A greater decrease in MR was associated with increased likelihood for GDMT uptitration., Competing Interests: Funding Support and Author Disclosures Dr Adamo has received speaker fees from Abbott Vascular and Medtronic.

Aims: This study aimed to compare outcomes after transcatheter mitral valve replacement (TMVR) and mitral valve transcatheter edge-to-edge repair (M-TEER) for the treatment of secondary mitral regurgitation (SMR)., Methods and Results: The CHOICE-MI registry included 262 patients with SMR treated with TMVR between 2014 and 2022. The EuroSMR registry included 1065 patients with SMR treated with M-TEER between 2014 and 2019. Propensity score (PS) matching was performed for 12 demographic, clinical and echocardiographic parameters. Echocardiographic, functional and clinical outcomes out to 1 year were compared in the matched cohorts. After PS matching, 235 TMVR patients (75.5 years [70.0, 80.0], 60.2% male, EuroSCORE II 6.3% [interquartile range 3.8, 12.4]) were compared to 411 M-TEER patients (76.7 years [70.1, 80.5], 59.0% male, EuroSCORE II 6.7% [3.9, 12.4]). All-cause mortality was 6.8% after TMVR and 3.8% after M-TEER at 30 days (p = 0.11), and 25.8% after TMVR and 18.9% after M-TEER at 1 year (p = 0.056). No differences in mortality after 1 year were found between both groups in a 30-day landmark analysis (TMVR: 20.4%, M-TEER: 15.8%, p = 0.21). Compared to M-TEER, TMVR resulted in more effective mitral regurgitation (MR) reduction (residual MR ≤1+ at discharge for TMVR vs. M-TEER: 95.8% vs. 68.8%, p < 0.001), and superior symptomatic improvement (New York Heart Association class ≤II at 1 year: 77.8% vs. 64.3%, p = 0.015)., Conclusion: In this PS-matched comparison between TMVR and M-TEER in patients with severe SMR, TMVR was associated with superior reduction of MR and superior symptomatic improvement. While post-procedural mortality tended to be higher after TMVR, no significant differences in mortality were found beyond 30 days., (© 2023 The Authors.

Background: Secondary mitral regurgitation (SMR) is a progressive disease with characteristic pathophysiological changes that may influence prognosis. Although the staging of SMR patients suffering from heart failure with reduced ejection fraction (HFrEF) according to extramitral cardiac involvement has prognostic value in medically treated patients, such data are so far lacking for edge-to-edge mitral valve repair (M-TEER)., Objectives: This study sought to classify M-TEER patients into disease stages based on the phenotype of extramitral cardiac involvement and to assess its impact on symptomatic and survival outcomes., Methods: Based on echocardiographic and clinical assessment, patients were assigned to 1 of the following HFrEF-SMR groups: left ventricular involvement (Stage 1), left atrial involvement (Stage 2), right ventricular volume/pressure overload (Stage 3), or biventricular failure (Stage 4). A Cox regression model was implemented to investigate the impact of HFrEF-SMR stages on 2-year all-cause mortality. The symptomatic outcome was assessed with New York Heart Association functional class at follow-up., Results: Among a total of 849 eligible patients who underwent M-TEER for relevant SMR from 2008 until 2019, 9.5% (n = 81) presented with left ventricular involvement, 46% (n = 393) with left atrial involvement, 15% (n = 129) with right ventricular pressure/volume overload, and 29% (n = 246) with biventricular failure. An increase in HFrEF-SMR stage was associated with increased 2-year all-cause mortality after M-TEER (HR: 1.39; CI: 1.23-1.58; P < 0.01). Furthermore, higher HFrEF-SMR stages were associated with significantly less symptomatic improvement at follow-up., Conclusions: The classification of M-TEER patients into HFrEF-SMR stages according to extramitral cardiac involvement provides prognostic value in terms of postinterventional survival and symptomatic improvement., Competing Interests: Funding Support and Author Disclosures Dr Orban has received speaker fees from Abbott Vascular and Tomtec Imaging Systems.

Background: Body surface area (BSA) has been reported to be the stronger predictor for prognosis than body mass index in heart failure (HF) patients. The sex-specific association of BSA with mortality has been unclear., Methods: EuroSMR, a European multicenter registry, included patients who underwent edge-to-edge repair (TEER) for secondary mitral regurgitation (SMR). The outcome was two-year all-cause mortality., Results: The present cohort included 1594 HF patients (age, 74 ± 10 years; male, 66%). Association of calculated BSA with two-year all-cause mortality was evaluated. Patients were classified into three BSA groups: the lowest 10% (S), the highest 10% (L), and intermediate between S and L (M). Mean BSA was 1.87 ± 0.21 m 2 (male, 1.94 ± 0.18 m 2 ; female, 1.73 ± 0.18 m 2 ). The association of BSA with the endpoint in females showed a U-shaped curve, indicating worse prognosis for both S and L. The association in males followed a linear regression, demonstrating better prognosis for L. Hazard ratio (HR) of L to S in males was 0.43 (95% confidence interval [CI], 0.25-0.74; p = 0.002), whereas HR of L to M in females was 1.76 (95% CI, 1.11-2.78; p = 0.016) (p for interaction = 0.003)., Conclusions: Sex-specific association patterns demonstrate the complex influence of anthropomorphic factors in HF patients scheduled for TEER. Further investigation beyond simple evaluation of weight and height is needed for better comprehension of the obesity paradox and better prediction of the results of transcatheter therapy in HF patients., Competing Interests: Conflicts of interest Dr. Higuchi has received lecture fees from Medtronic Japan, Daiichi Sankyo, and Ono Pharmaceutical Company.

Introduction and Objectives: The PASCAL system is a novel device for transcatheter mitral valve repair based on the edge-to-edge concept. The unique features of this device might have a relevant impact on the repair outcomes. There are few data on clinical outcomes in real-life registries. The aim of this study was to report the early Iberian experience (Spain and Portugal) of the PASCAL system., Methods: Procedural and 30-day outcomes were investigated in consecutive patients with symptomatic severe mitral regurgitation (MR) treated with the PASCAL system at 10 centers. Primary efficacy endpoints were technical success and degree of residual MR at discharge. The primary safety endpoint was the rate of major adverse events (MAE) at 30 days., Results: We included 68 patients (age, 75 [68-81] years; 38% women; EuroSCORE II 4.5%). MR etiology was degenerative in 25%, functional in 65%, and mixed in 10%. A total of 71% of patients were in New York Heart Association (NYHA) functional class≥III. Technical success was achieved in 96% and independent capture was used in 73% of procedures. In the treated population, MR at discharge was≤2+ in 100%, with no in-hospital deaths. At 30 days, the MAE rate was 5.9%, the all-cause mortality rate was 1.6%, 98% were in NYHA functional class≤II, and 95% had MR≤2+ (P<.001)., Conclusions: Transcatheter mitral valve repair with the PASCAL system was safe and effective, with high procedural success and low rates of MAE. At 30 days, MR was significantly reduced, with a significant improvement in functional status., (Copyright © 2022 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Aims: Guideline-directed medical therapy (GDMT), based on the combination of beta-blockers (BB), renin-angiotensin system inhibitors (RASI), and mineralocorticoid receptor antagonists (MRA), is known to have a major impact on the outcome of patients with heart failure with reduced ejection fraction (HFrEF). Although GDMT is recommended prior to mitral valve transcatheter edge-to-edge repair (M-TEER), not all patients tolerate it. We studied the association of GDMT prescription with survival in HFrEF patients undergoing M-TEER for secondary mitral regurgitation (SMR)., Methods and Results: EuroSMR, a European multicentre registry, included SMR patients with left ventricular ejection fraction <50%. The outcome was 2-year all-cause mortality. Of 1344 patients, BB, RASI, and MRA were prescribed in 1169 (87%), 1012 (75%), and 765 (57%) patients at the time of M-TEER, respectively. Triple GDMT prescription was associated with a lower 2-year all-cause mortality compared to non-triple GDMT (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.60-0.91). The association persisted in patients with glomerular filtration rate <30 ml/min, ischaemic aetiology, or right ventricular dysfunction. Further, a positive impact of triple GDMT prescription on survival was observed in patients with residual mitral regurgitation of ≥2+ (HR 0.62; 95% CI 0.44-0.86), but not in patients with residual mitral regurgitation of ≤1+ (HR 0.83; 95% CI 0.64-1.08)., Conclusion: Triple GDMT prescription is associated with higher 2-year survival after M-TEER in HFrEF patients with SMR. This association was consistent also in patients with major comorbidities or non-optimal results after M-TEER., (© 2022 The Authors.

Background: Among patients with severe functional mitral regurgitation (FMR), atrial functional mitral regurgitation (aFMR) represents an underrecognized entity. Data regarding outcomes after mitral valve transcatheter edge-to-edge repair (M-TEER) in aFMR remain scarce., Objectives: The objective of this study was to analyze the outcome of aFMR patients undergoing M-TEER., Methods: Using patients from the international EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) registry undergoing M-TEER for FMR, the authors analyzed baseline characteristics and 2-year outcomes in aFMR in comparison to non-aFMR and ventricular FMR. Additionally, the impact of right ventricular dysfunction (RVD) (defined as right ventricular to pulmonary artery uncoupling) on outcome after M-TEER was assessed., Results: Among 1,608 FMR patients treated by M-TEER, 126 (7.8%) were categorized as aFMR. All 126 aFMR patients had preserved left ventricular function without regional wall motion abnormalities, left arterial dilatation and Carpentier leaflet motion type I. Procedural success (defined as mitral regurgitation ≤2+ at discharge) was 87.2% (P < 0.001) and New York Heart Association (NYHA) functional class significantly improved during follow-up (NYHA functional class III/IV: 86.5% at baseline to 36.6% at follow-up; P < 0.001). The estimated 2-year survival rate in aFMR patients was 70.4%. Two-year survival did not differ significantly between aFMR, non-aFMR, and ventricular FMR. Besides NYHA functional class IV, RVD was identified as a strong independent predictor for 2-year survival (HR: 2.82 [95% CI: 1.24-6.45]; P = 0.014)., Conclusions: aFMR is a frequent cause of FMR and can be effectively treated with M-TEER to improve symptoms at follow-up. Advanced heart failure symptoms and RVD were identified as important risk factors for survival in aFMR patients., Competing Interests: Funding Support and Author Disclosures Dr Stolz has received travel expenses from Edwards LifeSciences.

Aims: To investigate the role of left atrial volume index (LAVi) in patients with secondary mitral regurgitation (SMR) undergoing transcatheter edge-to-edge mitral valve repair (TEER)., Methods and Results: Outcomes were evaluated in SMR patients of a European multicentre registry according to baseline LAVi. Main analysis was performed for all-cause mortality; residual mitral regurgitation (MR) and New York Heart Association (NYHA) class improvement were analysed for patients available. A total of 1074 patients were included with a median LAVi (interquartile range) of 58 ml/m 2 (46-73). Postprocedural reduction of MR grade to ≤2+ was similar across LAVi quintiles, ranging 91%-96% (p = 0.26). Symptomatic benefit (≥1 NYHA class improvement) also did not differ by LAVi quintiles (61%-68% of patients) (p = 0.66). The risk of mortality increased by 23%-42% in the four upper quintiles compared to the bottom quintile (LAVi <42 ml/m 2 ). The hazard ratio (HR) of mortality was 1.35 (95% confidence interval [CI] 1.02-1.78, p = 0.035) associated with a LAVi >42 ml/m 2 , which was attenuated after multivariable adjustment (HR 1.18, 95% CI 0.83-1.67, p = 0.36). A significant interaction was found for MR severity and pulmonary hypertension, with an increased risk of death associated with enlarged LAVi in patients with inframedian effective regurgitant orifice area (HR 1.99, 95% CI 1.06-3.74, p = 0.032) and in patients with systolic pulmonary pressure ≤50 mmHg (HR 1.67, 95% CI 1.02-2.75, p = 0.042) in multivariable analysis., Conclusion: Procedural success and symptomatic benefit were high throughout the whole range of LAVi. The prognostic impact of left atrial enlargement was relevant in patients with less severe SMR and without pulmonary hypertension, reinforcing the need to identify patients in the early course of backward congestion to achieve good long-term outcome after TEER., (© 2022 The Authors.

Background: Although mitral valve transcatheter edge-to-edge repair (M-TEER) achieves symptomatic benefit for a broad spectrum of patients with relevant secondary mitral regurgitation, conflicting data exist on its prognostic impact., Objectives: Adapted enrollment criteria approaching those used in the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) and MITRA-FR (Percutaneous Repair or Medical Treatment for Secondary Mitral Regurgitation) trials were retrospectively applied to a European real-world registry to evaluate the influence of the respective criteria on outcomes., Methods: A total of 1,022 patients included in the EuroSMR (European Registry of Transcatheter Repair for Secondary Mitral Regurgitation) registry and treated with M-TEER (November 2008 to September 2019) were stratified into COAPT-eligible (n = 353 [34.5%]) and COAPT-ineligible (n = 669 [65.5%]) as well as MITRA-FR-eligible (n = 408 [48.3%]) and MITRA-FR-ineligible (n = 437 [51.7%]) groups., Results: Although the stratification of patients according to adapted MITRA-FR criteria led to comparable outcomes regarding all-cause mortality (P = 0.19), the application of adapted COAPT enrollment criteria demonstrated lower mortality rates in COAPT-eligible compared with COAPT-ineligible patients (P < 0.001). Multivariable Cox regression analysis identified New York Heart Association functional class IV (hazard ratio [HR]: 2.29; 95% confidence interval [CI]: 1.53-3.42; P < 0.001), logarithmic N-terminal pro-brain natriuretic peptide (HR: 1.47; 95% CI: 1.24-1.75; P < 0.001), and right ventricular-to-pulmonary arterial coupling (HR: 0.10; 95% CI: 0.02-0.57; P = 0.009) as independent predictors of outcome. Yet improvement of functional outcome was demonstrated in a subset of patients irrespective of COAPT eligibility status., Conclusions: In this real-world cohort of patients with secondary mitral regurgitation undergoing M-TEER, the retrospective application of adapted COAPT enrollment criteria successfully identified a specific phenotype demonstrating lower mortality rates. On the contrary, stratification according to adapted MITRA-FR criteria resulted in comparable outcomes., Competing Interests: Funding Support and Author Disclosures Dr Orban has received speaker honoraria from Abbott Medical.
