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.
