Midterm Survival of Low-Risk Patients Treated With Transcatheter Versus Surgical Aortic Valve Replacement: Meta-Analysis of Reconstructed Time-to-Event Data.

Background We performed a meta-analysis of reconstructed time-to-event data from randomized controlled trials (RCTs) and propensity-score matched (PSM) studies comparing transcatheter versus surgical aortic valve replacement (TAVR versus SAVR) to evaluate midterm outcomes in patients considered low risk for SAVR. Methods and Results Study-level meta-analysis of reconstructed time-to-event data from Kaplan-Meier curves of RCTs and PSM studies published by December 31, 2022 was conducted. Eight studies (3 RCTs, 5 PSM studies) met our eligibility criteria and included 5444 patients; 2639 patients underwent TAVR, and 2805 patients underwent SAVR.

Sex-Related Differences in Clinical Outcomes After Thoracic Endovascular Aortic Repair.

Background Thoracic endovascular aortic repair (TEVAR) has been increasingly used for the treatment of descending thoracic aortic aneurysms and dissections. This study sought to evaluate the influence of sex on outcomes after TEVAR. Methods and Results This was an observational study from the Nationwide Readmissions Database analyzing all patients who underwent TEVAR from 2010 to 2018.

Misdiagnosis of Thoracic Aortic Emergencies Occurs Frequently Among Transfers to Aortic Referral Centers: An Analysis of Over 3700 Patients.

Background Acute aortic syndromes may be prone to misdiagnosis by nonreferral aortic centers with less diagnostic experience. We evaluated regional variability in these misdiagnosis trends among patients transferred to different regional quaternary care centers with presumed acute aortic syndromes. Methods and Results Two institutional aortic center databases were retrospectively reviewed for emergency transfers in patients diagnosed with acute aortic dissection, intramural hematoma, penetrating aortic ulcer, thoracic aortic aneurysm, or aortic pseudoaneurysm between 2008 and 2020.

Racial and Ethnic Differences in Cardiac Rehabilitation Participation: Effect Modification by Household Income.

Background Cardiac rehabilitation (CR) is associated with improved cardiovascular outcomes. Racial and ethnic differences in CR have been identified, but whether income may attenuate these disparities remains unknown. We evaluated (1) racial/ethnic differences in CR participation in a contemporary sample of insured US adults, and (2) assessed how household income modifies associations between race or ethnicity and CR participation.

Impact of an Automated Best Practice Alert on Sex and Race Disparities in Implantable Cardioverter-Defibrillator Therapy.

Background Implantable cardioverter-defibrillators (ICDs) are indicated in patients with severe left ventricular dysfunction, but many eligible patients do not receive them, especially women and Black patients. Our group had previously demonstrated that a best practice alert (BPA) improves overall rates of electrophysiology referrals and ICD implantations. This study examined the impact of a BPA by sex and race.

Levels and Change in Galectin-3 and Association With Cardiovascular Events: The ARIC Study.

Background Circulating galectin-3 levels provide prognostic information in patients with established heart failure (HF), but the associations between galectin-3 levels and other incident cardiovascular events in asymptomatic individuals at midlife and when remeasured ≈15 years later are largely uncharacterized. Methods and Results Using multivariable Cox proportional hazards models, we identified associations between plasma galectin-3 levels (hazard ratio [HR] per 1 SD increase in natural log galectin-3) and incident coronary heart disease, ischemic stroke, HF hospitalization, and total mortality in ARIC (Atherosclerosis Risk in Communities) participants free of cardiovascular disease at ARIC visit 4 (1996-1998; n=9247) and at ARIC visit 5 (2011-2013; n=4829). Higher galectin-3 level at visit 4 (median age 62) was independently associated with incident coronary heart disease (adjusted HR, 1.

Diversity, Inclusion, and Equity: Evolution of Race and Ethnicity Considerations for the Cardiology Workforce in the United States of America From 1969 to 2019.

Since 1969, racial and ethnic preferences have existed throughout the American medical academy. The primary purpose has been to increase the number of blacks and Hispanics within the physician workforce as they were deemed to be "underrepresented in medicine." To this day, the goal continues to be population parity or proportional representation.

Outcomes of Adult Heart Transplantation Using Hepatitis C-Positive Donors.

Background This study evaluated the impact of hepatitis C-positive (HCV+) donors on outcomes of heart transplantation in the United States. Methods and Results Adults undergoing isolated heart transplantation in the United States between January 1, 2016, and December 31, 2018, were included. The primary outcome was 1-year post-transplant survival.

Reflections on the early invasive clinical cardiac electrophysiology era through fifty manuscripts: 1967-1992.

In 1967, researchers in The Netherlands and France independently reported a new technique, later called programmed electrical stimulation. The ability to reproducibly initiate and terminate arrhythmias heralded the beginning of invasive clinical cardiac electrophysiology as a medical discipline. Over the next fifty years, insights into the pathophysiologic basis of arrhythmias would transform the field into an interventional specialty with a tremendous armamentarium of procedures.
