About Video

This video clip depicts two-dimensional transesophageal echocardiography. Color Doppler examination. Upper arrowhead points to a suture from a metallic prosthetic mitral valve (MV). Arrow shows reverberations from both leaflets of the prosthesis, numbered 1 and 2. MR represents severe paravalvular regurgitation. Both leaflets show intermittent “sticking” in the immediate post-bypass period because the hemodynamics had not normalized. Subsequently, with improved cardiac output, both leaflets showed normal motion. Thus, this finding should not lead to a misdiagnosis of prosthetic dysfunction. (LA: Left atrium; LV: Left ventricle; RA: Right atrium).
