BACKGROUND AND AIMS OF THE STUDY: Mitral valve prolapse due to floppy mitral valve (MVP/FMV) is a common valvular abnormality with a variable clinical course. Flail mitral valve leaflet resulting in severe mitral regurgitation is a complication of MVP/FMV. METHODS: In order to understand the structural correlates of flail mitral valve leaflet in MVP, we reviewed the morphologic characteristics of the mitral valve by transesophageal echocardiography (TEE) in 72 patients (24 normal; 26 mitral valve prolapse; 22 flail mitral valve leaflet). RESULTS: Compared with the normal group, the mitral valve prolapse group had greater anterior and posterior mitral valve leaflet thickness and anterior mitral valve leaflet length. Patients with flail mitral valve leaflets as a complication of FMV had greater anterior and posterior mitral valve leaflet length and posterior mitral valve leaflet thickness compared with MVP patients without flail mitral valve leaflets. Posterior mitral valve leaflet length was the only echocardiographic independent predictor of flail mitral valve leaflet. Older FMV patients with increased mitral valve leaflet length and thickness are predisposed to flail mitral valve leaflets and severe mitral regurgitation. CONCLUSIONS: TEE may identify patients with MVP/FMV with the greatest structural abnormalities who are at risk for complications such as flail mitral valve leaflet(s).
