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