Transvalvular Regurgitation across a Tilting Disk Prosthetic Mitral Valve: Role of Intraoperative Real-time Three-dimensional Transesophageal Echocardiography

摘要

Prosthetic valve regurgitation in the immediate post-implantation period can be caused by paravalvular or transvalvular leakage. Close examination with two-dimensional (2D) as well as three-dimensional (3D) transesophageal echocardiography (TEE) is necessary for its proper diagnosis. A case of transvalvular regurgitation across a tilting disk prosthetic valve in mitral position is described here, along with the role of 3D TEE in its diagnosis. Image acquisition and optimization for 3D TEE in prosthetic valve evaluation is also briefly reviewed.ggg3D echocardiography, Chitra heart valve prosthesis, Prosthetic valve dysfunction.
