Importance Transcatheter tricuspid valve replacement (TTVR) demonstrated superior outcomes over medical therapy in patients with severe tricuspid regurgitation (TR) in the Edwards EVOQUE Transcatheter Tricuspid Valve Replacement: Pivotal Clinical Investigation of Safety and Clinical Efficacy Using a Novel Device II (TRISCEND II) randomized clinical trial, and received regulatory approval in the US in 2024. Contemporary real-world data on its effectiveness and safety remain limited. Objective To evaluate 30-day clinical, echocardiographic, and health status outcomes of TTVR in real-world use. Design, Setting, and Population Retrospective cohort study of all consecutive patients who underwent TTVR in the US from February 2024 through March 2025 in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. Patients had symptomatic, severe TR despite optimal medical therapy and TTVR was deemed appropriate by a heart team. Statistical analysis was conducted from September 2025 to February 2026. Exposure Device-enabled TTVR. Main Outcomes and Measures Thirty-day event rates (all-cause death, stroke, bleeding, new cardiac implantable electronic device [CIED] implantation, heart failure hospitalizations), TR reduction, and changes in health status (New York Heart Association [NYHA] functional class and Kansas City Cardiomyopathy Questionnaire Overall Summary [KCCQ-OS] score) are reported. Subgroup analyses examined the impact of baseline CIED status on outcomes. Results Among 1034 attempted procedures at 82 centers (mean [SD] age, 77.1 [10.6] years; 69.1% female; 73.2% NYHA functional class III/IV), a valve was successfully implanted in 1017 patients (98.4%). Mild or less TR was achieved in 98.4% of patients post procedure and in 97.7% at 30 days. At 30 days, all-cause mortality was 3.1%; stroke, 0.2%; bleeding, 7.9%; new CIED, 15.9% in CIED-naive patients; and heart failure hospitalization, 3.1%. There were significant improvements in NYHA functional class (class I/II, 82.7%; P < .001) and mean KCCQ-OS score (22.4 points; P < .001) from baseline to 30 days. There were no significant differences in 30-day mortality ( P = .47), heart failure hospitalization ( P > .99), and functional outcomes ( P = .55) when patients were stratified by baseline CIED status. Conclusions and Relevance Early US real-world experience with TTVR confirms safety and effectiveness in patients with severe TR. Thirty-day outcomes are consistent with the TRISCEND II pivotal trial, demonstrating acceptable safety, near-complete TR elimination, and significant health status improvements in an older, comorbid population. Rates of new CIED implantation and bleeding were lower than randomized clinical trial experience.

Background: Randomized clinical trials are often criticized for not reflecting real-world practice. To understand the effect of site and patient selection on trial generalizability, we examined US patient and hospital participation within the Dual Antiplatelet Therapy (DAPT) Study, a broadly inclusive trial of PCI patients, using a linked analysis with the CathPCI Registry®. Methods: Within the CathPCI Registry, we identified patients undergoing PCI between September 1, 2009 and July 1, 2011 - the period of DAPT Study enrollment. We compared US patients enrolled in DAPT to CathPCI Registry patients meeting DAPT inclusion criteria. Characteristics of US DAPT sites were also compared to those of hospitals not participating in DAPT. Standardized differences (%) for all variables were estimated, with those greater than 10% considered significant. Results: Among 1,139,932 NCDR patients undergoing PCI, 748374 (65.7%) met the enrollment criteria for DAPT, and 23495 (2.1%) were enrolled. Enrolled patients were younger and had lower rates of prior stroke, CHF and peripheral vascular disease, but were similar with respect to race and gender compared with eligible patients (Table). Of the 1276 hospitals within the NCDR, 309 (24.2%) participated in DAPT. Hospital characteristics differed markedly, with DAPT-participating hospitals being larger (mean beds 468 vs. 311), more often located in urban settings (61.2% vs. 42.6%), more often affiliated with training programs (53.7% vs. 34.1%), and with higher annual PCI volumes (mean annual hospital volume 858 vs. 378 PCIs) compared with non-DAPT hospitals. Conclusions: While liberal inclusion criteria may allow randomized trials to better simulate “real-world” clinical practice, the process of site selection may encourage participation of higher volume, urban hospital settings. These findings are relevant to clinical trial interpretation and implementation of evidence-based practice throughout the healthcare system.

Antiplatelet therapy is the mainstay of pharmacologic treatment to prevent thrombotic or ischemic events in patients with coronary artery disease treated with percutaneous coronary intervention and those treated medically for an acute coronary syndrome. The use of antiplatelet therapy comes at the expense of an increased risk of bleeding complications. Defining the optimal intensity of platelet inhibition according to the clinical presentation of atherosclerotic cardiovascular disease and individual patient factors is a clinical challenge. Modulation of antiplatelet therapy is a medical action that is frequently performed to balance the risk of thrombotic or ischemic events and the risk of bleeding. This aim may be achieved by reducing (ie, de-escalation) or increasing (ie, escalation) the intensity of platelet inhibition by changing the type, dose, or number of antiplatelet drugs. Because de-escalation or escalation can be achieved in different ways, with a number of emerging approaches, confusion arises with terminologies that are often used interchangeably. To address this issue, this Academic Research Consortium collaboration provides an overview and definitions of different strategies of antiplatelet therapy modulation for patients with coronary artery disease, including but not limited to those undergoing percutaneous coronary intervention, and consensus statements on standardized definitions.

Background: Predicting technical failure in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can assist with decision making and planning of the procedure. Methods: We analyzed 6,946 CTO PCIs performed between 2016 and June 2022 at 36 international centers in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO) and created a score for risk of technical failure. Logistic regression prediction modeling was used to identify independently associated variables with technical failure and model were internally validated with bootstrapping. Results: Mean patient age was 64.0±10 years, 82% were men and technical success was 86%. The following variables were independently associated with technical failure and were included in the final model: age (odds ratio [OR]: 1.08, 95% Confidence Intervals [CI]: [1.00-1.15], p=0.039; age≥ 65 years; 1 point), CTO length (OR: 1.13, 95% CI [1.10, 1.17]; length≥ 20 mm; 1 point), moderate/severe calcification (OR: 1.35, 95% CI [1.17, 1.56]; 1 point), proximal cap ambiguity (OR: 2.25, 95% CI [1.95, 2.59]; 2 points), lack of interventional collaterals (OR: 1.60, 95% CI [1.39, 1.84]; 1 point), and lack of good distal landing zone (OR: 1.51, 95% CI [1.31, 1.75]; 1 point). The resulting score showed acceptable performance on receiver-operating characteristic (ROC) curve, AUC: 0.68 (95% CI [0.67-0.71]). Internal validation with bootstrapping of 1000 samples demonstrated a good agreement with the model, observed AUC: 0.68, (95% bias corrected CI [0.67, 0.70]). PROGRESS-CTO technical failure score and corresponding risk percentage and the percentage of patients in the respective risk group within the PROGRESS-CTO registry are represented in Figure 1. Conclusion: The updated PROGRESS CTO score may be useful for assessing the likelihood of technical failure success in CTO PCI.

Introduction: Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is associated with increased risk of periprocedural complications. Estimating the risk of complications facilitates risk-benefit assessment and procedural planning. Methods: We analyzed the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO, NCT02061436) and created a risk score for in-hospital all-cause mortality. Logistic regression prediction modeling was used to identify independently associated variables and the model was internally validated with bootstrapping. Results: Of the 10,480 CTO PCI cases performed between 2012-2022 at 40 US and non-US centers, in-hospital mortality occurred in 47 (0.45%). The final prediction model identified 4 independent predictors of mortality: Age ≥65 years, Odds Ratio [OR]: 2.83 (95% confidence interval [CI], 1.30-6.16), 1-point; Left ventricular ejection fraction ≤45%, OR: 2.13 (95% CI, 1.14-3.98), 1-point; Moderate-severe calcification, OR: 2.45 (95% CI, 1.18-5.08), 1-point; and Antegrade dissection re-entry, OR: 2.81 (95% CI, 1.06-7.43), 1-point; or Retrograde strategy, OR: 3.51 (95% CI, 1.67-7.37), 1-point; with a bootstrap corrected c-statistics of 0.71 (95% confidence interval: 0.63-0.81). The calculated risk percentages for mortality based on the PROGRESS-CTO mortality score ranged from 0.05-2.42% for mortality, and 63% of patients in the PROGRESS-CTO cohort had PROGRESS-CTO mortality score of 1 or 2, corresponding to a mortality risk of 0.1-0.5% (Figure 1). Conclusions: The PROGRESS-CTO in-hospital mortality risk score can facilitate risk-benefit assessment and procedural planning in patients undergoing CTO PCI.

Background: Black adults experience a disproportionately higher burden of cardiovascular risk factors and disease in comparison with White adults in the United States. Less is known about how sex-based disparities in cardiovascular mortality between these groups have changed on a national scale over the past 20 years, particularly across geographic determinants of health and residential racial segregation. Methods: We used CDC WONDER (Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research) to identify Black and White adults age ≥25 years in the United States from 1999 to 2019. We calculated annual age-adjusted cardiovascular mortality rates (per 100 000) for Black and White women and men, as well as absolute rate differences and rate ratios to compare the mortality gap between these groups. We also examined patterns by US census region, rural versus urban residence, and degree of neighborhood segregation. Results: From 1999 to 2019, age-adjusted mortality rates declined overall for both Black and White adults. There was a decline in age-adjusted cardiovascular mortality among Black (602.1 to 351.8 per 100 000 population) and White women (447.0 to 267.5), and the absolute rate difference (ARD) between these groups decreased over time (1999: ARD, 155.1 [95% CI, 149.9–160.3]; 2019: ARD, 84.3 [95% CI, 81.2–87.4]). These patterns were similar for Black (824.1 to 526.3 per 100 000) and White men (637.5 to 396.0; 1999: ARD, 186.6 [95% CI, 178.6–194.6]; 2019: ARD, 130.3 [95% CI, 125.6–135.0]). Despite this progress, cardiovascular mortality in 2019 was higher for Black women (rate ratio, 1.32 [95% CI, 1.30–1.33])— especially in the younger (age <65 years) subgroup (rate ratio, 2.28 [95% CI, 2.23–2.32])—as well as for Black men (rate ratio, 1.33 [95% CI, 1.32–1.34]), compared with their respective White counterparts. There was regional variation in cardiovascular mortality patterns, and the Black-White gap differed across rural and urban areas. Cardiovascular mortality rates among Black women and men were consistently higher in communities with high levels of racial segregation compared with those with low to moderate levels. Conclusions: During the past 2 decades, age-adjusted cardiovascular mortality declined significantly for Black and White adults in the United States, as did the absolute difference in death rates between these groups. Despite this progress, Black women and men continue to experience higher cardiovascular mortality rates than their White counterparts.

Background We systematically reviewed trials comparing different reperfusion strategies for ST‐segment–elevation myocardial infarction and used multivariate network meta‐analysis to compare outcomes across these strategies. Methods and Results We identified 31 contemporary trials in which patients with ST‐segment–elevation myocardial infarction were randomized to ≥2 of the following strategies: fibrinolytic therapy (n=4212), primary percutaneous coronary intervention ( PCI ) (n=6139), or fibrinolysis followed by routine early PCI (n=5006). We categorized the last approach as “facilitated PCI ” when the median time interval between fibrinolysis to PCI was <2 hours (n=2259) and as a “pharmacoinvasive approach” when this interval was ≥2 hours (n=2747). We evaluated outcomes of death, nonfatal reinfarction, stroke, and major bleeding using a multivariate network meta‐analysis and a Bayesian analysis. Among the strategies evaluated, primary PCI was associated with the lowest risk of mortality, nonfatal reinfarction, and stroke. For mortality, primary PCI had an odds ratio of 0.73 (95% CI , 0.61–0.89) when compared with fibrinolytic therapy. Of the remaining strategies, the pharmacoinvasive approach was the next most favorable with an odds ratio for death of 0.79 (95% CI , 0.59–1.08) compared with fibrinolytic therapy. The Bayesian model indicated that when the 2 strategies examining routine early invasive therapy following fibrinolysis were directly compared, the probability of adverse outcomes was lower for the pharmacoinvasive approach relative to facilitated PCI . Conclusions A pharmacoinvasive approach is safer and more effective than facilitated PCI and fibrinolytic therapy alone. This has significant implications for ST‐segment–elevation myocardial infarction care in settings where timely access to primary PCI , the preferred treatment for ST‐segment–elevation myocardial infarction , is not available.

Background Assessing hospital quality in the performance of carotid endarterectomy ( CEA ) requires appropriate risk adjustment across hospitals with varying case mixes. The aim of this study was to develop and validate a prediction model to assess the risk of in‐hospital stroke or death after CEA that could aid in the assessment of hospital quality. Methods and Results Patients from National Cardiovascular Data Registry (NCDR)'s Carotid Artery Revascularization and Endarterectomy (CARE) Registry undergoing CEA without acute evolving stroke from 2005 to 2013 were included. In‐hospital stroke or death was modeled using hierarchical logistic regression with 20 candidate variables and accounting for hospital‐level clustering. Internal validation was achieved with bootstrapping; model discrimination and calibration were assessed. A total of 213 (1.7%) primary end point events occurred during 12 889 procedures. Independent predictors of stroke or death included age, prior peripheral artery disease, diabetes mellitus, prior coronary artery disease, having a symptomatic carotid lesion, having a contralateral carotid occlusion, or having New York Heart Association Class III or IV heart failure. The model was well calibrated and demonstrated moderate discriminative ability (c‐statistic 0.65). The NCDR CEA score was then developed to support simple, prospective risk quantification in the clinical setting. Conclusions The NCDR CEA score, comprising 7 clinical variables, predicts in‐hospital stroke or death after CEA . This model can be used to estimate hospital risk‐adjusted outcomes for CEA and to assist with the assessment of hospital quality.
