Clinical Outcomes and Costs of Robotic-assisted vs Conventional Mitral Valve Repair: A National Analysis.

Background: Robotic approaches have been increasingly utilized for cardiothoracic operations, though concerns regarding costs remain. We evaluated short-term outcomes and costs of robotic-assisted and conventional mitral valve repair (MV-repair), hypothesizing that cost differences would be mitigated at high-volume programs.

Methods: Adults undergoing elective MV-repair from 2016 to 2020 were identified in the Nationwide Readmissions Database.

Hospital volume does not mitigate the impact of area socioeconomic deprivation on heart transplantation outcomes.

Background: While structural socioeconomic inequity has been linked with inferior health outcomes, some have postulated reduced access to high-quality care to be the mediator. We assessed whether treatment at high-volume centers (HVC) would mitigate the adverse impact of area deprivation on heart transplantation (HT) outcomes.

Methods: All HT recipients ≥18 years were identified in the 2005-2022 Organ Procurement and Transplantation Network.

Persistent income-based disparities in clinical outcomes of cardiac surgery across the United States: A contemporary appraisal.

Objective: Although national efforts have aimed to improve the safety of inpatient operations, income-based inequities in surgical outcomes persist, and the evolution of such disparities has not been examined in the contemporary setting. We sought to examine the association of community-level household income with acute outcomes of cardiac procedures over the past decade.

Methods: All adult hospitalizations for elective coronary artery bypass grafting/valve operations were tabulated from the 2010-2020 Nationwide Readmissions Database.

Decreased Left Atrial Cardiomyocyte FGF13 Expression Increases Vulnerability to Postoperative Atrial Fibrillation in Humans.

Postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery and a significant cause of increased morbidity and mortality. The development of novel POAF therapeutics has been limited by an insufficient understanding of molecular mechanisms promoting atrial fibrillation. In this observational cohort study, we enrolled 28 patients without a history of atrial fibrillation that underwent mitral valve surgery for degenerative mitral regurgitation and obtained left atrial tissue samples along the standard atriotomy incision in proximity to the right pulmonary veins.
