prolapse (MVP) is still debated. The aims of this study were to identify pre‐operatory parameters
predictive of residual MR and of early and long‐term favorable remodeling after MVP repair. We
included 295 patients who underwent MV repair for MVP with pre‐operatory two‐ and threedimensional
transthoracic echocardiography (2DTTE and 3DTTE) and 6‐months (6M) and 3‐years
(3Y) follow‐up 2DTTE. MVP was classified by 3DTTE as simple or complex and surgical procedures
as simple or complex. Pre‐operative echo parameters were compared to post‐operative values at 6M
and 3Y. Patients were divided into Group 1 (6M‐MR < 2) and Group 2 (6M‐MR ≥ 2), and predictors
of MR  2 were investigated. MVP was simple in 178/295 pts, and 94% underwent simple
procedures, while in only 42/117 (36%) of complex MVP a simple procedure was performed. A
significant relation among prolapse anatomy, surgical procedures and residual MR was found. Postoperative
MR ≥ 2 was present in 9.8%: complex MVP undergoing complex procedures had twice the
percentage of MR ≥ 2 vs. simple MVP and simple procedures. MVP complexity resulted
independent predictor of 6M‐MR ≥ 2. Favorable cardiac remodeling, initially found in all cases, was
maintained only in MR < 2 at 3Y. Pre‐operative 3DTTE MVP morphology identifies pts undergoing
simple or complex procedures predicting MR recurrence and favorable cardiac remodeling.
