- W2121820908 abstract "Abstract Background: Edge-to-edge mitral valve plasty technique has been widely used to treat bileaflet prolapse. This procedure anchors the correspondence leaflets to create a double-orifice mitral valve. The original mitral valve anatomy is changed, and the opening of mitral valve is restricted. Little is known whether this procedure affects the left ventricular diastolic function. Methods: Thirty patients with mitral regurgitation were included in this study. Fifteen with posterior leaflet prolapse received quadrangular resection (group 1), 15 with anterior or bileaflet prolapse underwent edge-to-edge procedure (group 2). Acute hemodynamics was monitored with a Swan-Ganz catheter (Edwards Lifesciences LLC, Irvine, CA, USA). Left ventricular diastolic function was also evaluated with echocardiography in 28 patients with sinus rhythm. The ratio of peak E velocity and A velocity (E/A), the ratio of early diastolic peak flow velocity to early diastolic mitral annular movement velocity (E/Em), and the ratio of early diastolic mitral annular velocity to late diastolic mitral annular velocity (Em/Am) were measured before operation and one week after operation. Results: Mitral valve area and mitral regurgitate grade decreased significantly after operation. There was no significant change in pulmonary artery wedge pressure between two groups and in each group before and after operation. Echocardiography evaluation showed there was no significant difference in E/A, E/Em, and Em/Am before and after operation between two groups and in each group. Conclusion: Edge-to-edge mitral valve plasty procedure has no significant impairment on left ventricular diastolic function. A double-orifice mitral valve has similar hemodynamic behavior with a physiological valve. (J Card Surg 2010;25:5-8)" @default.
