Does early surgical intervention improve left ventricular mass regression after mitral valve repair for leaflet prolapse?

Performing mitral valve repair before a decrease in left ventricular ejection fraction and the development of significant secondary tricuspid valve regurgitation is associated with a greater likelihood of significant regression of left ventricular mass, possibly predicting improved recovery of normal left ventricular function after surgical intervention. These data provide additional support for early degenerative mitral valve repair.
