Transcatheter Mitral Valve Therapy in the United States: A Report from the STS/ACC TVT Registry.

Data for nearly all patients undergoing transcatheter edge-to-edge repair (TEER) and transcatheter mitral valve replacement (TMVR) with an approved device in the United States is captured in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. All data submitted for TEER or TMVR between 2014 and March 31, 2020, are reported. A total of 37,475 patients underwent a mitral transcatheter procedure, including 33,878 TEER and 3,597 TMVR. Annual procedure volumes for TEER have increased from 1,152 per year in 2014 to 10,460 per year in 2019 at 403 sites and for TMVR from 84 per year to 1,120 per year at 301 centers. Mortality rates have decreased for TEER at 30 days (5.6%-4.1%) and 1 year (27.4%-22.0%). Early off-label use data on TMVR in mitral valve-in-valve therapy led to approval by the U.S. Food and Drug Administration in 2017, and the 2019 30-day mortality rate was 3.9%. Overall improvements in outcomes over the last 6 years are apparent. (STS/ACC TVT Registry Mitral Module; NCT02245763).

Best Practice Recommendations for Optimizing Care in Structural Heart Programs: Planning Efficient and Resource Leveraging Systems (PEARLS).

The COVID19 pandemic brought unprecedented disruption to healthcare. Staggering morbidity, mortality, and economic losses prompted the review and refinement of care for structural heart disease (SHD). To mitigate negative impacts in the face of crisis or capacity constraints, this paper offers best practice recommendations for Planning Efficient and Resource Leveraging Systems (PEARLS) in structural heart programs. A systematic assessment is recommended for hospital capacity, Heart Team roles and functions, and patient and procedural risks associated with increased resource utilization. Strategies, tactics, and pathways are provided for the delivery of patient-centered, efficient and resource-leveraging care from referral to follow-up. Through the optimal use of capacity and resources, paired with dynamic triage, forecasting, and surveillance, Heart Teams may aspire to plan and implement an optimized system of care for SHD.

STS-ACC TVT Registry of Transcatheter Aortic Valve Replacement.

The STS-ACC TVT Registry (Society of Thoracic Surgeons-American College of Cardiology Transcatheter Valve Therapy Registry) from 2011 to 2019 has collected data on 276,316 patients undergoing transcatheter aortic valve replacement (TAVR) at sites in all U.S. states. Volumes have increased every year, exceeding surgical aortic valve replacement in 2019 (72,991 vs. 57,626), and it is now performed in all U.S. states. TAVR now extends from extreme- to low-risk patients. This is the first presentation on 8,395 low-risk patients treated in 2019. In 2019, for the entire cohort, femoral access increased to 95.3%, hospital stay was 2 days, and 90.3% were discharged home. Since 2011, the 30-day mortality rate has decreased (7.2% to 2.5%), stroke has started to decrease (2.75% to 2.3%), but pacemaker need is unchanged (10.9% to 10.8%). Alive with acceptable patient-reported outcomes is achieved in 8 of 10 patients at 1 year. The Registry is a national resource to improve care and analyze TAVR's evolution. Real-world outcomes, site performance, and the impact of coronavirus disease 2019 will be subsequently studied. (STS/ACC Transcatheter Valve Therapy Registry [TVT Registry]; NCT01737528).

2016 Annual Report of The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry.

BACKGROUND: The Society of Thoracic Surgeons (STS)/American College of Cardiology Transcatheter Valve Therapy (TVT) Registry captures all procedures with Food and Drug Administration-approved transcatheter valve devices performed in the United States, and is mandated as a condition of reimbursement by the Centers for Medicaid & Medicare Services. OBJECTIVES: This annual report focuses on patient characteristics, trends, and outcomes of transcatheter aortic and mitral valve catheter-based valve procedures in the United States. METHODS: We reviewed data for all patients receiving commercially approved devices from 2012 through December 31, 2015, that are entered in the TVT Registry. RESULTS: The 54,782 patients with transcatheter aortic valve replacement demonstrated decreases in expected risk of 30-day operative mortality (STS Predicted Risk of Mortality [PROM]) of 7% to 6% and transcatheter aortic valve replacement PROM (TVT PROM) of 4% to 3% (both p < 0.0001) from 2012 to 2015. Observed in-hospital mortality decreased from 5.7% to 2.9%, and 1-year mortality decreased from 25.8% to 21.6%. However, 30-day post-procedure pacemaker insertion increased from 8.8% in 2013 to 12.0% in 2015. The 2,556 patients who underwent transcatheter mitral leaflet clip in 2015 were similar to patients from 2013 to 2014, with hospital mortality of 2% and with mitral regurgitation reduced to grade ≤2 in 87% of patients (p < 0.0001). The 349 patients who underwent mitral valve-in-valve and mitral valve-in-ring procedures were high risk, with an STS PROM for mitral valve replacement of 11%. The observed hospital mortality was 7.2%, and 30-day post-procedure mortality was 8.5%. CONCLUSIONS: The TVT Registry is an innovative registry that that monitors quality, patient safety and trends for these rapidly evolving new technologies.

Annual Outcomes With Transcatheter Valve Therapy: From the STS/ACC TVT Registry.

BACKGROUND: The Society of Thoracic Surgeons (STS)/American College of Cardiology (ACC) Transcatheter Valve Therapy (TVT) Registry has been a joint initiative of the STS and the ACC in concert with multiple stakeholders. The TVT Registry has important information regarding patient selection, delivery of care, science, education, and research in the field of structural valvular heart disease. OBJECTIVES: This report provides an overview on current U.S. TVT practice and trends. The emphasis is on demographics, in-hospital procedural characteristics, and outcomes of patients having transcatheter aortic valve replacement (TAVR) performed at 348 U.S. centers. METHODS: The TVT Registry captured 26,414 TAVR procedures as of December 31, 2014. Temporal trends between 2012 and 2013 versus 2014 were compared. RESULTS: Comparison of the 2 time periods reveals that TAVR patients remain elderly (mean age 82 years), with multiple comorbidities, reflected by a high mean STS predicted risk of mortality (STS PROM) for surgical valve replacement (8.34%), were highly symptomatic (New York Heart Association functional class III/IV in 82.5%), frail (slow 5-m walk test in 81.6%), and have poor self-reported health status (median baseline Kansas City Cardiomyopathy Questionnaire score of 39.1). Procedure performance is changing, with an increased use of moderate sedation (from 1.6% to 5.1%) and increase in femoral access using percutaneous techniques (66.8% in 2014). Vascular complication rates are decreasing (from 5.6% to 4.2%), whereas site-reported stroke rates remain stable at 2.2%. CONCLUSIONS: The TVT Registry provides important information on characteristics and outcomes of TAVR in contemporary U.S. clinical practice. It can be used to identify trends in practice and opportunities for quality improvement.

Outcomes following transcatheter aortic valve replacement in the United States.

IMPORTANCE: Transcatheter aortic valve replacement (TAVR) was approved by the US Food and Drug Administration for the treatment of severe, symptomatic aortic stenosis and inoperable status (in 2011) and high-risk but operable status (starting in 2012). A national registry (the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy [STS/ACC TVT] Registry) was initiated to meet a condition for Medicare coverage and also facilitates outcome assessment and comparison with other trials and international registries. OBJECTIVE: To report the initial US commercial experience with TAVR. DESIGN, SETTING, AND PARTICIPANTS: We obtained results from all eligible US TAVR cases (n=7710) from 224 participating registry hospitals following the Edwards Sapien XT device commercialization (November 2011-May 2013). MAIN OUTCOMES AND MEASURES: Primary outcomes included all-cause in-hospital mortality and stroke following TAVR. Secondary analyses included procedural complications and outcomes by clinical indication and access site. Device implantation success was defined as successful vascular access, deployment of a single device in the proper anatomic position, appropriate valve function without either moderate or severe AR, and successful retrieval of the delivery system. Thirty-day outcomes are presented for a representative 3133 cases (40.6%) at 114 centers with at least 80% complete follow-up reporting. RESULTS: The 7710 patients who underwent TAVR included 1559 (20%) cases that were inoperable and 6151 (80%) cases that were high-risk but operable. The median age was 84 years (interquartile range [IQR], 78-88 years); 3783 patients (49%) were women and the median STS predicted risk of mortality was 7% (IQR, 5%-11%). At baseline, 2176 patients (75%) were either not at all satisfied (1297 patients [45%]) or mostly dissatisfied (879 patients [30%]) with their symptom status; 2198 (72%) had a 5-m walk time longer than 6 seconds (slow gait speed). The most common vascular access approach was transfemoral (4972 patients [64%]), followed by transapical (2197 patients [29%]) and other alternative approaches (536 patients [7%]); successful device implantation occurred in 7069 patients (92%; 95% CI, 91%-92%). The observed incidence of in-hospital mortality was 5.5% (95% CI, 5.0%-6.1%). Other major complications included stroke (2.0%; 95% CI, 1.7%-2.4%), dialysis-dependent renal failure (1.9%; 95% CI, 1.6%-2.2%), and major vascular injury (6.4%; 95% CI, 5.8%-6.9%). Median hospital stay was 6 days (IQR, 4-10 days), with 4613 (63%) discharged home. Among patients with available follow-up at 30 days (n=3133), the incidence of mortality was 7.6% (95% CI, 6.7%-8.6%) (noncardiovascular cause, 52%); a stroke had occurred in 2.8% (95% CI, 2.3%-3.5%), new dialysis in 2.5% (95% CI, 2.0%-3.1%), and reintervention in 0.5% (95% CI, 0.3%-0.8%). CONCLUSIONS AND RELEVANCE: Among patients undergoing TAVR at US centers in the STS/ACC TVT Registry, device implantation success was achieved in 92% of cases, the overall in-hospital mortality rate was 5.5%, and the stroke rate was 2.0%. Although these postmarket US approval findings are comparable with prior published trial data and international experience, long-term follow-up is essential to assess continued efficacy and safety.

Quality-of-life changes following the completion of phase II cardiac rehabilitation.

In this study, 302 patients who were completing Phase II cardiac rehabilitation were assessed at their entrance to cardiac rehabilitation and at 3 months. After 3 months, subjects improved on 8 of 9 dimensions. Greatest gains were in Fitness (22.5%, P < .0001) and Daily Activities (24.4%, P < .0001). Despite stratification by gender, a sedentary lifestyle, and tobacco use, quality of life was markedly improved at the completion of rehabilitation. Completion of a Phase II cardiac rehabilitation program can lead to statistically significant increases in the quality of life following consequential cardiac events.
