RESUMO
BACKGROUND: Bioprosthetic surgical mitral valve replacement (SMVR) remains an important treatment option in the era of transcatheter valve interventions. We present 10-year clinical outcomes of Medicare beneficiaries undergoing SMVR with a contemporary low-profile mitral porcine valve. METHODS: This is a single-arm observational study using Medicare fee-for-service claims data. De-identified patients undergoing SMVR with the Epic™ Mitral valve (Abbott, Minnesota, USA) in the United States between 1/1/2008-12/31/2019 were selected by ICD-9/10 procedure codes and then linked to a manufacturer device tracking database. All-cause mortality, heart failure (HF) re-hospitalization, and mitral valve reintervention (surgical or transcatheter valve-in-valve) were evaluated at 10-years using the Kaplan Meier method. RESULTS: Among 75,739 Medicare beneficiaries undergoing SMVR during the study period, 14,015 were implanted with the Epic™ Mitral valve, of which 76.5% (10,720) had underlying HF. Mean age was 74±8 years. Survival at 10-years in patients without preoperative HF was 40.4% (95% CI 37.4%-43.4%) compared to 25.4% (95% CI 23.8%-27.0%) for patients with HF (p < 0.001). The 10-year freedom from HF rehospitalization was 51.3% (95% CI 49.4%-53.1%). Freedom from mitral valve reintervention was 91.4% (95% CI 89.7%-92.7%) at 10 years. CONCLUSIONS: This real-world nationwide study of Medicare beneficiaries receiving the Epic™ Mitral valve demonstrates >90% freedom from all-cause valve reintervention and >50% freedom from HF rehospitalization at 10-years post-implant. Long-term survival and HF rehospitalization in this population with mitral valve disease undergoing SMVR was found to be impacted by underlying HF.
RESUMO
The association, if any, between the effective regurgitant orifice area (EROA) to left ventricular end-diastolic volume (LVEDV) ratio and 1-year mortality is controversial in patients who undergo mitral transcatheter edge-to-edge repair (m-TEER) with the MitraClip system (Abbott Vascular, Santa Clara, CA). This study's objective was to determine the association between EROA/LVEDV and 1-year mortality in patients who undergo m-TEER with MitraClip. In patients with severe secondary (functional) mitral regurgitation (MR), we analyzed registry data from 11 centers using generalized linear models with the generalized estimating equations approach. We studied 525 patients with secondary MR who underwent m-TEER. Most patients were male (63%) and were New York Heart Association class III (61%) or IV (21%). Mitral regurgitation was caused by ischemic cardiomyopathy in 51% of patients. EROA/LVEDV values varied widely, with median = 0.19 mm2/ml, interquartile range [0.12,0.28] mm2/ml, and 187 patients (36%) had values <0.15 mm2/ml. Postprocedural mitral regurgitation severity was substantially alleviated, being 1+ or less in 74%, 2+ in 20%, 3+ in 4%, and 4+ in 2%; 1-year mortality was 22%. After adjustment for confounders, the logarithmic transformation (Ln) of EROA/LVEDV was associated with 1-year mortality (odds ratio 0.600, 95% confidence interval 0.386 to 0.933, p = 0.023). A higher Society of Thoracic Surgeons risk score was also associated with increased mortality. In conclusion, lower values of Ln(EROA/LVEDV) were associated with increased 1-year mortality in this multicenter registry. The slope of the association is steep at low values but gradually flattens as Ln(EROA/LVEDV) increases.

Objective: Novel tissue leaflets (RESILIA tissue) may improve durability of bioprosthetic heart valves. The COMMENCE trial is an ongoing prospective study to evaluate valve replacement using RESILIA tissue. This report describes mid-term outcomes in the mitral cohort of COMMENCE. Methods: Adult patients requiring mitral valve replacement were enrolled in a prospective, single-arm trial at 17 sites in the United States and Canada. An independent clinical events committee adjudicated safety events using definitions from established guidelines, and hemodynamic performance was evaluated by an independent echocardiographic core laboratory. Results: Eighty-two patients (median age 70 years) successfully underwent mitral valve replacement with the study valve. Five-year event-free probabilities for all-cause mortality, structural valve deterioration, and reoperation were 79.9%, 98.7%, and 97.1%, respectively. Hemodynamic valve function measurements were stable through the 5-year follow-up period; valvular leaks were infrequently observed and primarily clinically insignificant/mild. Conclusions: Mitral valve replacement patients implanted with a RESILIA tissue bioprosthesis had a good safety profile and clinically stable hemodynamic performance.
RESUMO
BACKGROUND: The fourth-generation mitral transcatheter edge-to-edge repair (M-TEER) device introduced an improved clip deployment sequence, independent leaflet grasping, and 2 wider clip sizes to tailor the treatment of patients with mitral regurgitation (MR) for a broad range of anatomies. The 30-day safety and effectiveness of the fourth-generation M-TEER device were previously demonstrated. OBJECTIVES: The aim of this study was to evaluate 1-year outcomes in a contemporary, real-world cohort of subjects treated with the MitraClip G4 system. METHODS: EXPAND G4 is an ongoing prospective, multicenter, international, single-arm study that enrolled subjects with primary and secondary MR. One-year outcomes included MR severity (echocardiographic core laboratory assessed), heart failure hospitalization, all-cause mortality, functional capacity (NYHA functional class), and quality of life (Kansas City Cardiomyopathy Questionnaire). RESULTS: A total of 1,164 subjects underwent M-TEER from 2020 to 2022. At 1 year, there was a durable reduction in MR to mild or less in 92.6% and to none or trace in 44.2% (P < 0.0001 vs baseline). Few subjects had major adverse events through 1 year (<2% for myocardial infarction, surgical reintervention, or single-leaflet device attachment). The 1-year Kaplan-Meier estimates for all-cause mortality and heart failure hospitalization were 12.3% and 16.9%. Significant improvements in functional capacity (NYHA functional class I or II in 82%; P < 0.0001 vs baseline) and quality of life (18.5-point Kansas City Cardiomyopathy Questionnaire overall summary score improvement; P < 0.0001) were observed. CONCLUSIONS: M-TEER with the fourth-generation M-TEER device was safe and effective at 1 year, with durable reductions in MR severity to ≤1+ in more than 90% of patients and concomitant improvements in functional status and quality of life.

AIM: The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS: A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. STRUCTURE: Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

BACKGROUND: The fourth-generation MitraClip G4 System builds on the previous NTR/XTR system with additional wider clip sizes (NTW and XTW), an independent grasping feature, and an improved clip deployment sequence. OBJECTIVES: The primary objective of this study was to assess the safety and performance of the MitraClip G4 System within a contemporary real-world setting. METHODS: EXPAND G4 is a prospective, multicenter, international, single-arm, postapproval study that enrolled patients with primary (degenerative) mitral regurgitation (MR) and secondary (functional) MR at 60 centers. Follow-up of the full cohort has been conducted through 30 days. Echocardiograms were analyzed by an echocardiography core laboratory. Study outcomes included MR severity, functional capacity measured by NYHA functional class, quality of life measured using the Kansas City Cardiomyopathy Questionnaire, major adverse event rates, and all-cause mortality. RESULTS: In EXPAND G4, 1,141 subjects with primary MR and secondary MR were treated from March 2021 to February 2022. Implantation and acute procedural success rates were 98.0% and 96.2%, respectively, with a mean of 1.4 ± 0.6 clips implanted per subject. MR was significantly reduced at 30 days compared with baseline (98% achieved MR ≤ 2+, and 91% achieved MR ≤ 1+; P < 0.0001). Functional capacity and quality of life were substantially improved, with 83% of patients achieving NYHA functional class I or II. Likewise, an 18-point improvement was observed in Kansas City Cardiomyopathy Questionnaire summary scores compared with baseline. The composite major adverse event rate was 2.7%, and the all-cause death rate was 1.3% at 30 days. CONCLUSIONS: This study demonstrates for the first time the effectiveness and safety of MitraClip G4 System at 30 days in a cohort of >1,000 patients with MR in a contemporary, real-world setting.

BACKGROUND: Anatomical and clinical criteria to define mitral transcatheter edge-to-edge repair (TEER) "unsuitability" have been proposed on the basis of a Heart Valve Collaboratory consensus opinion from physician experience with early-generation TEER devices but lacked an evidence-based approach. OBJECTIVES: The aim of this study was to explore the spectrum of TEER suitability using echocardiographic and clinical outcomes from the EXPAND G4 real-world postapproval study. METHODS: EXPAND G4 is a global, prospective, multicenter, single-arm study that enrolled 1,164 subjects with mitral regurgitation (MR) treated with the MitraClip G4 System. Three groups were defined using the Heart Valve Collaboratory TEER unsuitability criteria: 1) risk of stenosis (RoS); 2) risk of inadequate MR reduction (RoIR); and 3) subjects with baseline moderate or less MR (MMR). A TEER-suitable (TS) group was defined by the absence of these characteristics. Endpoints included independent core laboratory-assessed echocardiographic characteristics, procedural outcomes, MR reduction, NYHA functional class, Kansas City Cardiomyopathy Questionnaire score, and major adverse events through 30 days. RESULTS: Subjects in the RoS (n = 56), RoIR (n = 54), MMR (n = 326), and TS (n = 303) groups had high 30-day MR reduction rates (≤1+: RoS 97%, MMR 93%, and TS 91%; ≤2+: RoIR 94%). Thirty-day improvements in functional capacity (NYHA functional class I or II at 30 days vs baseline: RoS 94% vs 29%, RoIR 88% vs 30%, MMR 79% vs 26%, and TS 83% vs 33%) and quality of life (change in Kansas City Cardiomyopathy Questionnaire score: RoS +27 ± 26, RoIR +16 ± 26, MMR +19 ± 26, and TS +19 ± 24) were safely achieved in all groups, with low major adverse events (<3%) and all-cause mortality (RoS 1.8%, RoIR 0%, MMR 1.5%, and TS 1.3%). CONCLUSIONS: Patients previously deemed TEER unsuitable can be safely and effectively treated with the mitral TEER fourth-generation device.

BACKGROUND: Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) is increasingly used to treat degenerated surgical bioprostheses. Bioprosthetic valve fracture (BVF) has been shown to improve hemodynamic status in VIV TAVR in case series. However, the safety and efficacy of BVF are unknown. OBJECTIVES: The primary objective of this study was to assess the safety and efficacy of VIV TAVR using SAPIEN 3 and SAPIEN 3 Ultra valves with or without BVF using data from the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry. METHODS: The primary outcome was in-hospital mortality. Secondary outcomes included echocardiography-derived valve gradient and aortic valve area. Inverse probability of treatment weighting was used to adjust for baseline characteristics. RESULTS: A total of 2,975 patients underwent VIV TAVR from December 15, 2020, to March 31, 2022. BVF was attempted in 619 patients (21%). In adjusted analyses, attempted BVF was associated with higher in-hospital mortality (OR: 2.51; 95% CI: 1.30-4.84) and life-threatening bleeding (OR: 2.55; 95% CI: 1.44-4.50). At discharge, VIV TAVR with attempted BVF was associated with larger aortic valve area (1.6 cm2 vs 1.4 cm2; P < 0.01) and lower mean gradient (16.3 mm Hg vs 19.2 mm Hg; P < 0.01). When BVF was compared with no BVF according to timing (before vs after transcatheter heart valve implantation), BVF after transcatheter heart valve implantation was associated with improved hemodynamic status and similar mortality. CONCLUSIONS: BVF as an adjunct to VIV TAVR with the SAPIEN 3 and SAPIEN 3 Ultra valves is associated with a higher risk for in-hospital mortality and significant bleeding and modest improvements in echocardiography-derived hemodynamic status. The timing of BVF is an important determinant of safety and efficacy.

OBJECTIVE: Up to 28% of patients may need mitral valve (MV) surgery after transcatheter edge-to-edge repair (TEER). This study evaluates the outcomes of minimally invasive MV surgery after TEER. Methods: International multicenter registry of minimally invasive MV surgery after TEER between 2013 and 2020. Subgroups were stratified by the number of devices implanted (≤1 vs >1), as well as time interval from TEER to surgery (≤1 year vs >1 year). Results: A total of 56 patients across 13 centers were included with a mean age of 73 ± 11 years, and 50% were female. The median Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) score for MV replacement was 8% (Q1-Q3 = 5% to 11%) and the ratio of observed to expected mortality was 0.9. The etiology of mitral regurgitation (MR) prior to TEER was primary MR in 75% of patients and secondary MR in 25%. There were 30 patients (54%) who had >1 device implanted. The median time between TEER and surgery was 252 days (33 to 636 days). Hemodynamics, including MR severity, MV area, and mean gradient, significantly improved after minimally invasive surgery and sustained to 1-year follow-up. In-hospital and 30-day mortality was 7.1%, and 1-year actuarial survival was 85.6% ± 6%. Conclusions: Minimally invasive MV surgery after TEER may be achieved as predicted by the STS PROM. Most patients underwent MV replacement instead of repair. As TEER is applied more widely, patients should be informed about the potential need for surgical intervention over time after TEER. These discussions will allow better informed consent and post-procedure planning.

OBJECTIVES: There are minimal data regarding clinical outcomes and echocardiographic findings after transcatheter mitral valve-in-valve replacement (TMVR) compared with redo surgical mitral valve replacement (SMVR). BACKGROUND: TMVR therapy has emerged as therapy for a degenerated bioprosthetic valve failure. METHODS: The authors retrospectively identified patients with degenerated mitral bioprostheses who underwent redo SMVR or TMVR at 3 U.S. institutions. The authors compared clinical and echocardiographic outcomes of patients who had TMVR with those of patients who underwent redo SMVR. RESULTS: Sixty-two patients underwent TMVR and 59 patients underwent SMVR during the study period. Mean age and the Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) scores were significantly higher in patients with TMVR than in those with SMVR (age 74.9 ± 9.4 years vs. 63.7 ± 14.9 years; p < 0.001; STS PROM 12.7 ± 8.0% vs. 8.7 ± 10.1%; p < 0.0001). Total procedure time, intensive care unit hours, and post-procedure length of stay were all significantly shorter in the TMVR group. There was no difference in mortality at 1 year between the 2 groups (TMVR 11.3% vs. SMVR 11.9%; p = 0.92). Mean mitral valve pressure gradient and the grade of mitral regurgitation (MR) were similar between the TMVR group and the SMVR group (mitral valve pressure gradient 7.1 ± 2.5 mm Hg vs. 6.5 ± 2.5 mm Hg; p = 0.42; MR [≥moderate] 3.8% vs. 5.6%; p = 1.00) at 30 days. At 1 year, the mitral valve pressure gradient was higher in the TMVR group (TMVR 7.2 ± 2.7 vs. SMVR 5.5 ± 1.8; p = 0.01), although there was no difference in the grade of MR. CONCLUSIONS: Despite the higher STS PROM in TMVR patients, there was no difference in 1-year mortality between the TMVR and SMVR groups. Echocardiographic findings after TMVR were similar to SMVR at 30 days. There was a statistically significant difference in mitral gradient at 1 year, though this is likely not clinically important. TMVR may be an alternative to SMVR in patients with previous mitral bioprosthetic valves.

BACKGROUND: The TRANSFORM (Multicenter Experience With Rapid Deployment Edwards INTUITY Valve System for Aortic Valve Replacement) trial (NCT01700439) evaluated the performance of the INTUITY rapid deployment aortic valve replacement (RDAVR) system in patients with severe aortic stenosis. METHODS: TRANSFORM was a prospective, nonrandomized, multicenter (n = 29), single-arm trial. INTUITY is comprised of a cloth-covered balloon-expandable frame attached to a Carpentier-Edwards PERIMOUNT Magna Ease aortic valve. Primary and effectiveness endpoints were evaluated at 1 year. RESULTS: Between 2012 and 2015, 839 patients underwent RDAVR. Mean age was 73.5 ± 8.3 years. Full sternotomy (FS) was used in 59% and minimally invasive surgical incisions in 41%. Technical success rate was 95%. For isolated RDAVR, mean crossclamp and cardiopulmonary bypass times for FS were 49.3 ± 26.9 minutes and 69.2 ± 34.7 minutes, respectively, and for minimally invasive surgical 63.1 ± 25.4 minutes and 84.6 ± 33.5 minutes, respectively. These times were favorable compared with Society of Thoracic Surgeons database comparators for FS: 76.3 minutes and 104.2 minutes, respectively, and for minimally invasive surgical, 82.9 minutes and 111.4 minutes, respectively (P < .001). At 30 days, all-cause mortality was 0.8%; valve explant, 0.1%; thromboembolism, 3.5%; and major bleeding, 1.3%. In patients with isolated aortic valve replacement, the rate of permanent pacemaker implantation was 11.9%. At 1 year, mean effective orifice area was 1.7 cm2; mean gradient, 10.3 mm Hg; and moderate and severe paravalvular leak, 1.2% and 0.4%, respectively. CONCLUSIONS: INTUITY RDAVR performed effectively in this North American trial. It may lead to a relative reduction in aortic crossclamp time and cardiopulmonary bypass time and has excellent hemodynamic performance. Pacemaker implantation rate observed was somewhat greater than European trials and requires further investigation.
