Association of Transcatheter Mitral Valve Repair Availability With Outcomes of Mitral Valve Surgery.

Background Transcatheter mitral valve repair (TMVr) is currently offered at selected centers that meet certain operator and institutional requirements. We sought to explore the hypothesis that the availability of TMVr is associated with improved outcomes of MV surgery. Methods and Results We used the Nationwide Readmissions Database to identify patients who underwent MV surgery at centers with or without TMVr capabilities between January 1 and December 31, 2017.

Determinants of Morbidity and Mortality Associated With Isolated Tricuspid Valve Surgery.

Background Whether the poor outcomes of isolated tricuspid valve surgery are related to the operation itself or to certain patient characteristics including late referral is unknown. Methods and Results Adult patients who underwent isolated tricuspid valve surgery were identified in the Nationwide Readmissions Database (2016-2017). Patients who had redo tricuspid valve surgery, endocarditis, or congenital heart disease were excluded.
