Key result
Primary mitral valve prolapse has become the most common cause of surgically treated mitral regurgitation, accounting for 60% of all patients operated on between 1970 and 1990.

Etiology shift in surgical MR may guide case selection; leaves open whether prolapse predominance persists in contemporary cohorts.

What are the changing aetiologies of surgically treated mitral regurgitation over time?
The study highlights a shift in the etiology of surgically treated mitral regurgitation, with primary mitral valve prolapse replacing rheumatic fever as the most common cause.
Luxereau et al. (1991) conducted an observational in Mitral regurgitation (n=336). Surgical treatment was evaluated on Aetiology of mitral regurgitation. Primary mitral valve prolapse has become the most common cause of surgically treated mitral regurgitation, accounting for 60% of all patients operated on between 1970 and 1990.
