To evaluate the impact of coronary artery disease (CAD), percutaneous coronary intervention (PCI), and coronary lesion complexity on outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis. This retrospective study included 1042 patients divided into two groups by the presence or absence of CAD (SYNTAX score 0, no history of revascularization). Propensity score matching was used to compare the two groups. The effect of PCI, SYNTAX score, and residual SYNTAX score was also analyzed. The median age of the cohort was 82 years, and 641 patients had CAD. After propensity score matching, 346 pairs were analyzed. During 5 years of follow-up (median: 25, range 0–72 months), the rate of coronary intervention was significantly higher in CAD patients (p = 0.018). However, all-cause mortality, composite of all-cause mortality, stroke, and coronary intervention, and overt bleeding defined by VARC-3 were comparable. After stratification, in patients with creatinine ≥1.5 mg/dl, CAD was associated with a worse composite outcome (p = 0.016). Neither PCI nor SYNTAX score was associated with all-cause mortality in CAD patients. Similarly, residual SYNTAX score showed no association with mortality in patients undergoing PCI (all p values >0.7). PCI did not reach a significant difference in overt bleeding in CAD patients (adjusted p = 0.06). Despite a higher incidence of coronary interventions, major clinical outcomes were similar between patients with and without CAD after TAVR. In patients with chronic kidney disease, CAD may be associated with an adverse composite outcome. Neither PCI nor SYNTAX/residual SYNTAX score influenced all-cause mortality. • The impact of Coronary artery disease (CAD), PCI, and SYNTAX score on TAVR. • Higher incidence of coronary intervention after TAVR in patients with CAD. • Otherwise comparable outcomes between CAD and no CAD patients up to 5 years • Possible worse clinical outcome of CAD in patients with CKD. • No effect of PCI or SYNTAX/residual SYNTAX score on mortality after TAVR.

The following document includes the discussion and summary of the current state of valve therapy and the needs being addressed for valve development.

Background: Transaxillary (TAx) transcatheter aortic valve implantation (TAVI) is a preferred alternative access in patients ineligible for transfemoral TAVI. Aims: This study used the Trans-AXillary Intervention (TAXI) registry to compare procedural success according to different types of transcatheter heart valves (THV). Methods: For the TAXI registry anonymized data of patients treated with TAx-TAVI were collected from 18 centers. Acute procedural, early and 1-month clinical outcomes were adjudicated in accordance with standardized VARC-3 definitions. Results: From 432 patients, 368 patients (85.3%, SE group) received self-expanding (SE) THV and 64 patients (14.8%, BE group) received balloon-expandable (BE) THV. Imaging revealed lower axillary artery diameters in the SE group (max/min diameter in mm: 8.4/6.6 vs 9.4/6.8 mm; p < 0.001/p = 0.04) but a higher proportion of axillary tortuosity in BE group (62/368, 23.6% vs 26/64, 42.6%; p = 0.004) with steeper aorta-left ventricle (LV) inflow (55° vs 51°; p = 0.002) and left ventricular outflow tract (LVOT)-LV inflow angles (40.0° vs 24.5°; 0.002). TAx-TAVI was more often conducted by right sided axillary artery in the BE group (33/368, 9.0% vs 17/64, 26.6%; p < 0.001). Device success was higher in the SE group (317/368, 86.1% vs 44/64, 68.8%, p = 0.0015). In logistic regression analysis, BE THV were a risk factor for vascular complications and axillary stent implantation. Conclusions: Both, SE and BE THV can be safely used in TAx-TAVI. However, SE THV were more often used and were associated with a higher rate of device success. While SE THV were associated with lower rates of vascular complications, BE THV were more often used in cases with challenging anatomical circumstances. [ABSTRACT FROM AUTHOR]

Therapeutic options for patients with isolated severe to torrential tricuspid regurgitation have been limited. Because a surgical option is often not attractive, new catheter-based therapies are emerging. We report the first-in-human percutaneous transcatheter tricuspid valve replacement with the MonarQ system in a 75-year-old female patient with severely symptomatic torrential tricuspid regurgitation.

Primary or secondary tricuspid regurgitation (TR) represents an important health care burden and challenge which has often been neglected or undertreated in the past. The expansion and reinforcement of the indications for tricuspid valve (TV) intervention in the 2017 editions of the guidelines as well as the introduction of transcatheter tricuspid valve intervention (TTVI) has considerably increased the attention of the community on the TV and the volume of TV interventions in the past years. Depending on the anatomic target, TTVI can be categorized as the following: 1) direct or indirect tricuspid restrictive annuloplasty; 2) direct (edge-to-edge repair) or indirect (coaptation device) restoration of leaflet coaptation; 3) heterotopic tricuspid valve implantation; and 4) transcatheter tricuspid valve replacement. Multimodality imaging has crucial role for the following: 1) patient selection for TTVI and procedure planning; 2) guiding and monitoring the procedure; and 3) assessing and following over time the results of the procedure. The key points for pre-procedural imaging are: 1) accurate quantitation of TR severity; 2) proper identification of the mechanism(s) responsible for the TR; and 3) quantitation of RV dysfunction and pulmonary arterial hypertension. This imaging work-up is essential to select the right type of intervention for the right patient and TV. Transesophageal echocardiography and fluoroscopy imaging is also key for guiding the TTVI procedures and fusion between these 2 modalities may further enhance the quality of procedure guiding. • The volume of surgical and transcatheter valve interventions has increased in the past years. • Multimodality imaging is essential for assessing patient's eligibility for TV intervention, guiding procedure, and assessing outcomes. • Key points for preprocedural imaging of TV intervention are accurate quantitation of TR severity, identification of TR mechanisms, and quantitation of RV dysfunction. • TEE and cinefluoroscopy are keys for guiding the TV interventions. • Fusion imaging and 3D TEE are helpful for more complex TV procedures such as TriClip and transcatheter annuloplasty.

Objectives: To assess the impact of concomitant mitral stenosis (MS) on early and late outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis., Methods: This study involved 952 patients undergoing TAVR for severe tricuspid aortic stenosis. The patients were classified into 3 groups: without MS, with progressive MS, and severe MS (mitral valve area ≤ 1.5 cm2). Clinical outcomes between these groups were compared., Results: The median age of the overall cohort was 82 years, and patients in the progressive (n = 49) and severe (n = 24) MS groups were more likely to be female than those in the no-MS group (n = 879). Periprocedural mortality rate was lowest in the no-MS group (1.8%) compared with the progressive (4.1%) and severe (4.2%) MS groups, which were not significantly different (P = .20). During 5 years of follow-up (median: 27, range: 0-72 months), there was no significant difference in all-cause mortality (log-rank P = .99), a composite of all-cause mortality or rehospitalization for heart failure (log-rank P = .84), or cardiovascular death (log-rank P = .57) between groups. Although crude analysis showed a significant difference in rehospitalization for heart failure in the severe MS group compared with the no-MS group (P = .049), the difference was not significant in the multivariate analysis (adjusted hazard ratio: 1.36 [95% CI, 0.66-2.80], P = .41)., Conclusions: TAVR can be safely performed in patients with severe tricuspid aortic stenosis and concomitant MS, with early and mid-term outcomes comparable to those in patients without MS.

The past 2 decades have seen a proliferation of transcatheter mitral valve (MV) therapies, which are less invasive and distinct from surgical MV repair or replacement. The commonly used MV transcatheter therapies include (1) percutaneous mitral balloon commissurotomy (PMBC) for rheumatic mitral stenosis; (2) edge-to-edge repair with the MitraClip for mitral regurgitation; (3) valve-in-valve implantation in bioprosthetic MV, native MV, or mitral ring; and (4) closure of paravalvular leaks (PVLs). This article will focus on the use of echocardiography in the diagnosis, patient selection, procedural guidance, and postprocedural follow-up for PMBC, with notes on the role of transesophageal echocardiography in transcatheter interventions for prosthetic valve degeneration and PVL closure.

Over the last few decades, there have been dramatic advances in the understanding of the mechanisms of valvular heart disease and development of percutaneous treatment options. These innovations have resulted in the need for a multidisciplinary heart team approach for quality patient outcomes, a team in which nursing is an integral member. This update provides an overview of the major valve diseases, current guideline recommendations, catheter-based treatment options and key elements of nursing care: physical examination, diagnostic testing, pre- and post-procedure care protocols, and patient education elements., (Copyright © 2023 Elsevier Inc.

Objectives: We herein report a single-center experience with the Portico TAVI system. Main focus was set on outcomes in patients with impaired left ventricular (LV) function and predictors for permanent pacemaker (PPM) implantation.Methods: Between 05/2014 and 10/2017, 106 consecutive patients received TAVI using the Portico device. For comparison of patients with/without impaired LV function, and determination of multi-slice computed tomography and electrocardiogram correlates for PPM implantation subgroups were built (Subgroup I: LVEF ≥ 50%, n = 69, Subgroup II: LVEF < 50%, n = 37; Subgroup A: no PPM implantation, n = 89; Subgroup B: PPM implantation, n = 17). Data were retrospectively analyzed.Results: Device success was 95.3% (101/106) with resulting transvalvular peak/mean pressure gradients of 10.6 ± 5.6/5.4 ± 3.1 and PVL ≥ moderate in 5/106 patients (4.7%). 30-day mortality was 4.7% (5/106; subgroup I 3/69, 4.3%; subgroup II 2/37, 5.4%; p = 1.0). Regarding VARC-2 adjudicated clinical endpoints stroke (3/106, 2.8%; subgroups I/II: 2/69 vs. 1/37, p = 1.0) and acute kidney injury (9/106, 8.5%; subgroups I/II: 6/69 vs. 3/37, p = 1.0), no significant differences were found. Postprocedural PPM implantation occurred in 17.9% (19/106) of the patients. Logistic regression for PPM implantation demonstrated predictive character of left coronary cusp (LCC) calcium load in zone 1 (annular plane to coronary ostia) (p = 0.05, threshold 193 mm3) and total calcium load of zone 1 (p = 0.05, threshold 751.2 mm3).Conclusions: The Portico valve demonstrates a satisfying safety outcome, especially for patients with impaired LV function. Results of the CE-mark trial were confirmed, except for higher PPM rates. PPM rates are in accordance with other reports on this TAVI platform. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Moderate or severe degree tricuspid valve regurgitation (TVR) is associated with high rates of morbidity and mortality. Surgical correction as the only therapeutic option offers unsatisfactory results. Recently, several interventional procedures have been introduced clinically in a limited cohort.We present our initial experiments with an innovative interventional valved stent graft for treatment of TVR. METHODS: A newly designed porcine pericardium-covered nitinol stent graft with a lateral bicuspid valve was adapted to size in a cadaver study. After haemodynamic testing in an ex vivo perfusion setup, vascular access, valve delivery and function were investigated in an ovine animal model (n = 7). RESULTS: The device was implanted successfully in all animals. Vascular access was established surgically via the femoral vein without any vascular complications. Angiography demonstrated the correct position of the device with proper sealing of both venae cavae in 6 animals. In 1 extremely large animal, the position of the device was considered too cranial but still acceptable. Correct valve function was verified in all animals by both angiography and echocardiography. There were no persistent arrhythmias other than during valve implant. All animals survived the implant procedure and were sacrificed electively. CONCLUSIONS: This study demonstrated that this new valved stent graft could be delivered safely with correct positioning and valve function in this ovine model. Further long-term studies in animals implanted with the device after creation of tricuspid regurgitation are necessary to prove the haemodynamic benefit of this procedure. [ABSTRACT FROM AUTHOR]

The PARTNER group recently published a comparison between the latest generation SAPIEN 3 transcatheter aortic valve implantation (TAVI) system (Edwards Lifesciences, Irvine, CA, USA) and surgical aortic valve replacement (SAVR) in intermediate-risk patients, apparently demonstrating superiority of the TAVI and suggesting that TAVI might be the preferred treatment method in this risk class of patients. Nonetheless, assessment of the non-randomized methodology used in this comparison reveals challenges that should be addressed in order to elucidate the validity of the results. The study by Thourani and colleagues showed several major methodological concerns: suboptimal methods in propensity score analysis with evident misspecification of the propensity scores (PS; no adjustment for the most significantly different covariates: left ventricular ejection fraction, moderate-severe mitral regurgitation and associated procedures); use of PS quintiles rather than matching; inference on not-adjusted Kaplan-Meier curves, although the authors correctly claimed for the need of balancing score adjusting for confounding factors in order to have unbiased estimates of the treatment effect; evidence of poor fit; lack of data on valve-related death. These methodological flaws invalidate direct comparison between treatments and cannot support authors' conclusions that TAVI with SAPIEN 3 in intermediate-risk patients is superior to surgery and might be the preferred treatment alternative to surgery.

OBJECTIVES: The published literature has extensively documented clinical benefit derived from transcatheter aortic valve implantation (TAVI) in high-risk patients using self-expanding current-generation transfemoral (TF) transcatheter heart valves (THVs). However, it has also demonstrated apparent shortcomings such as paravalvular leakage (PVL) or need for permanent pacemaker (PM) implantation. We here present a case-matched analysis of acute 30-day outcomes using a novel nitinol-based THV (Symetis Acurate Neo TF?), which may overcome some limitations of currently used devices. METHODS: From 2012 to 2015, 69 consecutive patients (study group, 65.2% female, 81.4 ± 6.1 years, logEuroSCORE I 19.9 ± 14.2%) received TF-TAVI using the novel Symetis Acurate Neo TF? THV. A control group of patients after TF-TAVI with the CoreValve? THV was retrieved from our database (control group) and matched to the study group utilizing 16 parameters. Data were retrospectively analysed according to updated Valve Academic Research Consortium (VARC-2) definitions. The 30-day follow-up was completed in all cases. RESULTS: Apart from gender (65.2 vs 44.9% females, P = 0.023), matching was successful with parameters showing no significant differences. The device success rate was 95.6% (66/69) and 89.9% (62/69) in the study and control groups, respectively (P = 0.20). The all-cause 30-day mortality rate was 5.8% (4/69) vs 10.14% (7/69) (P = 0.36), and disabling stroke was observed in 2.9% (2/69) vs 5.8% (4/69) (P = 0.41), respectively. Resultant transvalvular maximum/mean gradient and effective orifice area (EOA) were 13.8 ± 5.5 vs 18.1 ± 8.1 mmHg (P = 0.001)/7.0 ± 2.8 vs 8.8 ± 4.0 mmHg (P = 0.006) and 1.9 ± 0.3 vs 1.8 ± 0.2 cm² (P = 0.015), respectively. PVL =grade II was observed in 2.9% (2/69) and 15.94% (11/69) (P = 0.013) of patients and the rate of PMimplantation was 8.7% (6/69) vs 44.9% (31/69) (P < 0.001), respectively. DISCUSSION: TF-TAVI was feasible and safe using this new type of nitinol-based THV. Superiority to the current generation of self-expanding THVs was achieved regarding post-interventional pressure gradients and EOA, severity of residual PVL and rate of PM implantation. Results set a promising quality standard for TF-TAVI with a self-expanding THV, but will have to be confirmed in a larger patient cohorts for further clinical evaluation. [ABSTRACT FROM AUTHOR]

Background: Previous studies of the cost-effectiveness of transcatheter aortic valve replacement (TAVR) have been based primarily on a single balloon-expandable system.Objectives: The goal of this study was to evaluate the cost-effectiveness of TAVR with a self-expanding prosthesis compared with surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis and high surgical risk.Methods: We performed a formal economic analysis on the basis of individual, patient-level data from the CoreValve U.S. High Risk Pivotal Trial. Empirical data regarding survival and quality of life over 2 years, and medical resource use and hospital costs through 12 months were used to project life expectancy, quality-adjusted life expectancy, and lifetime medical costs in order to estimate the incremental cost-effectiveness of TAVR versus SAVR from a U.S.Results: Relative to SAVR, TAVR reduced initial length of stay an average of 4.4 days, decreased the need for rehabilitation services at discharge, and resulted in superior 1-month quality of life. Index admission and projected lifetime costs were higher with TAVR than with SAVR (differences $11,260 and $17,849 per patient, respectively), whereas TAVR was projected to provide a lifetime gain of 0.32 quality-adjusted life-years ([QALY]; 0.41 LY) with 3% discounting. Lifetime incremental cost-effectiveness ratios were $55,090 per QALY gained and $43,114 per LY gained. Sensitivity analyses indicated that a reduction in the initial cost of TAVR by ∼$1,650 would lead to an incremental cost-effectiveness ratio <$50,000/QALY gained.Conclusions: In a high-risk clinical trial population, TAVR with a self-expanding prosthesis provided meaningful clinical benefits compared with SAVR, with incremental costs considered acceptable by current U.S.Standards: With expected modest reductions in the cost of index TAVR admissions, the value of TAVR compared with SAVR in this patient population would become high.

Abstract: Aims: Prospective data on the usage of 3-dimensional imaging based annulus sizing on the outcome of TAVI is not available yet and there is general uncertainty about the optimal degree of oversizing. In the current study we therefore assessed a 3-D MSCT guided over-sizing approach and evaluated the clinical outcome of different degrees of oversizing. Methods: TAVI-size-selection was done using systolic MSCT-annulus cross-sectional-area (CSA) measurements in 107 patients with severe aortic stenosis with the goal to oversize the 3rd generation balloon expandable Edwards Sapien XT (ESTV) device in relation to the native aortic annulus CSA. Results: Among different degrees of oversizing there were no differences in the occurrence of stroke, myocardial infarction and death. No aortic injuries were observed. The overall rate of >mild postprocedural aortic regurgitation (PAR) was 7.6%. Increasing oversizing ratios are associated with lower rates of >mild PAR (r=−0.236, p<0.02) with the lowest rate of >mild PAR in patients with area based oversizing ratios >25% and the highest rate in patients with oversizing ratios <15% (0% vs. 15.8%, p<0.02). The rate of postprocedural permanent pacemakers tended to be lower in patients with <15% oversizing compared to those with >25% oversizing (5.3 vs. 16.7%, p<0.23). Conclusions: MSCT guided ESTV-device sizing is safe and is associated with significantly lower than previously reported rates for PAR. A device/annulus oversizing ratio of 15–25% based on area and 7–12% based on mean diameter appears to provide the best risk-benefit ratio in terms of PAR reduction and conduction disorders.

Objectives: The goal of this study was to assess the performance and incidence of the deterioration of the Labcor Dokimos bioprosthetic aortic valve., Methods: We performed a retrospective medical chart review of 116 patients who underwent surgical aortic valve replacement with the Labcor Dokimos aortic valve between 2010 and 2018. Abstracted data included patient demographic and echocardiographic data. Patients were divided into 2 groups: patients with structural valve deterioration (SVD) and patients without SVD., Results: Among the patients with complete follow-up (n = 95), 10 patients were excluded because they died within a year; 85 patients were included in the final analysis. Of the 85 patients, 32 (38%) developed SVD; 22 (26%) had severe SVD, 15 (18%) of whom underwent reintervention. The most common aetiology of SVD was severe central aortic regurgitation, which was detected in 91% of the patients who had severe SVD. The average time from operation to severe SVD was 4.7 years with a minimum of 1.5 years and a maximum of 7.9 years., Conclusions: Bioprosthetic aortic valve deterioration due to severe aortic regurgitation is common and occurs early with the Labcor Dokimos valve. This occurrence needs to be furthered investigated in larger registries., (© The Author(s) 2021.

Background--In patients with severe aortic stenosis who cannot have surgery, transcatheter aortic valve replacement (TAVR) has been shown to improve survival and quality of life compared with standard therapy, but the costs and cost-effectiveness of this strategy are not yet known. Methods and Results--The PARTNER trial randomized patients with symptomatic, severe aortic stenosis who were not candidates for surgery to TAVR (n=179) or standard therapy (n=179). Empirical data regarding survival, quality of life, medical resource use, and hospital costs were collected during the trial and used to project life expectancy, quality-adjusted life expectancy, and lifetime medical care costs to estimate the incremental cost-effectiveness of TAVR from a US perspective. For patients treated with TAVR, mean costs for the initial procedure and hospitalization were $42 806 and $78 542, respectively. Follow-up costs through 12 months were lower with TAVR ($29 289 versus $53 621) because of reduced hospitalization rates, but cumulative 1-year costs remained higher ($106 076 versus $53 621). We projected that over a patient's lifetime, TAVR would increase discounted life expectancy by 1.6 years (1.3 quality-adjusted life-years) at an incremental cost of $79 837. The incremental cost-effectiveness ratio for TAVR was thus estimated at $50 200 per year of life gained or $61 889 per quality-adjusted life-year gained. These results were stable across a broad range of uncertainty and sensitivity analyses. Conclusions--For patients with severe aortic stenosis who are not candidates for surgery, TAVR increases life expectancy at an incremental cost per life-year gained well within accepted values for commonly used cardiovascular technologies.

Objectives: We herein report a single-centre experience with the SAPIEN 3 Ultra balloon-expandable transcatheter aortic valve implantation (TAVI) system., Methods: Between March 2019 and January 2020, a total of 79 consecutive patients received transfemoral TAVI using the SAPIEN 3 Ultra device. Data were retrospectively analysed according to updated Valve Academic Research Consortium-2 definitions. Detailed analysis of multislice computed tomography data was conducted to identify potential predictors for permanent pacemaker (PPM) implantation and residual paravalvular leakage (PVL) post TAVI., Results: Device success and early safety were 97.5% (77/79) and 94.9% (75/79) with resulting transvalvular peak/mean pressure gradients of 21.1 ± 8.2/10.9 ± 4.4 and PVL >mild in 0/79 patients (0%). Mild PVL was seen in 18.9% (15/79) of cases. Thirty-day mortality was 2.5% (2/79). The Valve Academic Research Consortium-2 adjudicated clinical end points disabling stroke, acute kidney injury and myocardial infarction occurred in 1.3% (1/79), 5.1% (4/79) and 0% (0/79) of patients. Postprocedural PPM implantation was necessary in 7.6% (6/79) of patients. Multislice computed tomography analysis revealed significantly higher calcium amounts of the right coronary cusp in patients in need for postprocedural PPM implantation and a higher eccentricity index in patients with postinterventional mild PVL., Conclusions: First experience with this newly designed balloon-expandable-transcatheter heart valve demonstrates adequate 30-day outcomes and haemodynamic results with low mortality, low rates of PPM implantation and no residual PVL >mild. The herein-presented multislice computed tomography values with an elevated risk for PPM implantation and residual mild PVL may help to further improve outcomes with this particular transcatheter heart valve in TAVI procedures., (© The Author(s) 2020.

Objectives: We herein aimed to compare acute 30-day outcomes of latest-generation self-expandable and balloon-expandable transcatheter heart valves., Methods: From 2012 through 2016, 104 consecutive patients (study group, 69.2% female, 81.7 ± 5.5 years, logEuroSCORE I 15.9 ± 9.3%) received transfemoral transcatheter aortic valve implantation using the Symetis ACURATE neo® transcatheter heart valve. A control group of patients after transfemoral transcatheter aortic valve implantation with the Edwards Sapien 3™ transcatheter heart valve was retrieved from our database and matched to the study group. Data were retrospectively analysed according to updated Valve Academic Research Consortium definitions., Results: Device success was 94.2% (98 of 104) and 98.1% (102 of 104) in study and control groups, respectively (P = 0.157). All-cause 30-day mortality was 3.9 (4 of 104) vs 0.9% (1 of 104) (P = 0.317). Resultant transvalvular peak/mean gradients and effective orifice area were 14.2 ± 5.7 vs 22.6 ± 6.8 mmHg (P < 0.001)/7.3 ± 2.8 vs 11.8 ± 3.5 mmHg (P < 0.001) and 2.0 ± 0.4 vs 1.7 ± 0.4 cm2 (P = 0.063). Paravalvular leakage ≥moderate was observed in 4.8% (5 of 104) and 1.9% (2 of 104) (P = 0.257). Rate of permanent pacemaker implantation was 10.6% (11 of 104) vs 16.4% (17 of 104) (P = 0.239)., Conclusions: Next-generation self-expandable transcatheter heart valves preserve superiority in terms of post-interventional haemodynamics without presenting former drawbacks: rate of postoperative permanent pacemaker implantation and severity of residual paravalvular leakage were similar to balloon-expandable transcatheter heart valves., (© The Author 2017.

Objectives: The aim of this study was to compare early outcomes and survival of patients undergoing minimally invasive mitral valve replacement through a right anterior minithoracotomy (MIMVR) versus patients undergoing transcatheter transapical mitral valve-in-valve (M-VIV) implantation for a failed mitral bioprostheses., Methods: From 2005 to 2015, 61 patients with a failed mitral bioprosthesis underwent either MIMVR ( n  = 40 patients, 65.6%) or M-VIV implantation ( n  = 21, 34.4%) at our institution. The groups were compared in terms of early outcomes and survival rates. Treatment selection bias was controlled by a propensity score and was included along with the comparison variable in the multivariable analyses of outcome., Results: Patients with M-VIV implantation were older ( P  = 0.03), had more pulmonary hypertension ( P  = 0.02) and a higher EuroSCORE ( P  = 0.001). In-hospital mortality was 7.5% ( n  = 3) in the MIMVR group and 4.7% ( n  = 1) in the M-VIV group [odds ratio (OR) = 2.46; P  = 0.512]. Incidence of stroke was 12.5% ( n  = 5) in the MIMVR group vs 4.7% ( n  = 1) in the M-VIV group (OR = 0.887; P  = 0.935). No significant differences were noted in postprocedural complications, even after adjusting the results for the propensity score. M-VIV patients had shorter stays in the intensive care unit and in the hospital ( P  = 0.02). In the M-VIV group, 28% ( n  = 7) had less than mild paravalvular leakage, whereas no patients had mild paravalvular leakage in the MIMVR group ( P  < 0.001). Finally, the 2-year survival rates were 86 ± 1% vs 87 ± 1% in patients undergoing MIMVR compared with those undergoing M-VIV implantation, respectively ( P  = 0.1)., Conclusions: In selected patients, M-VIV can be performed safely with results comparable with those of surgical therapy., (© The Author 2017.
