About Video

This video demonstrates two-dimensional transesophageal echocardiography in a patient with bioprosthetic mitral valve replacement (MVR). Arrow points to prominent shadowing produced by the metallic components of the prosthesis which effectively block passage of the ultrasound beam so that none of the structures behind them are imaged. (LA: Left atrium; LAA: Left atrial appendage; LV: Left ventricle).
