An Alternative Approach for Mitral Paravalvular Leak with Dacron Patch Curtaining under the Guidance of Real-Time 3-Dimensional Transesophageal Echocardiography

Objectives: The aim of this study was to evaluate real-time 3-dimensional transesophageal echocardiography (RT-3D TEE) in the assessment of mitral paravalvular leakage curtaining surgery with a Dacron patch. Methods: RT-3D TEE was used before and after the operation. Results: Repairing a mitral paravalvular leak with Dacron patch curtaining was a useful, simple and new technique with promising feasibility and durability. Conclusions: In selected patients in whom the mitral paravalvular defect is relatively large, and may thus not be suitable for closing with primary suture, Dacron patch curtaining may be feasible for repair guided with RT-3D TEE; both are described for the first time.
