Does higher hospital and surgeon volume reduce 30-day and 1-year mortality in patients undergoing mitral valve surgery for primary mitral regurgitation?
Higher hospital and surgeon volumes are associated with lower 30-day and 1-year mortality after mitral valve surgery for primary mitral regurgitation.
National hospital- and surgeon-level inverse volume-outcome associations were observed for 30-day and 1-year mortality after mitral valve surgery for primary mitral regurgitation. These findings may help to define access to experienced centers and surgeons for the management of primary mitral regurgitation.
Badhwar et al. (2020) studied this question.
