Association of hospital surgical aortic valve replacement quality with 30-day and 1-year mortality after transcatheter aortic valve replacement
JAMA Cardiology Jan 21, 2019
Kundi H, et al. - In this national cohort including US patients 65 years and older, researchers investigated whether hospitals with better patient outcomes for surgical aortic valve replacement (SAVR) subsequently achieve better transcatheter aortic valve replacement (TAVR) outcomes after launching TAVR programs. The analysis included only hospitals performing at least 1 SAVR prior to September 1, 2011 and performing at least 1 TAVR after this date. This study included 51,924 TAVR procedures, of which 19,798 were performed at hospitals in quartile 1 (the lowest risk-adjusted SAVR mortality rate), 7,663 were performed in quartile 2, 10,180 were performed in quartile 3, and 14,283 were performed in quartile 4 (the highest risk-adjusted SAVR mortality rate). Findings revealed higher short-term and long-term TAVR mortality after initiating TAVR programs for hospitals with higher SAVR mortality rates. Quality of cardiac surgical care may be related to a hospital’s performance with new structural heart disease programs.
