About Video

This video clip shows two-dimensional transesophageal echocardiography (intraoperative). Mitral prosthetic valve dysfunction. Leaflet #2 of the mitral prosthesis (MVR) is stuck in the closed position. The other leaflet (#1) moves well. No thrombus is evident on the atrial aspect. The ventricular aspect of the prosthesis cannot be adequately evaluated because of reverberations and shadowing effect from the metallic components of the prosthesis. During surgery, a large thrombus (arrow) was removed from the prosthesis with normal return of motion of the previously stuck leaflet (#2) and no significant mitral regurgitation (MR). This patient also underwent tricuspid valve replacement (TVR). (AV: Aortic valve; LA: Left atrium; LV: Left ventricle; RA: Right atrium; RV: Right ventricle).
