This video clip presents two-dimensional transesophageal echocardiography in the operating room. Color Doppler examination. Arrow shows mitral regurgitation. Arrowhead indicates multiple artifacts resulting from the use of cautery during surgery. So far there is no effective method to eliminate these artifacts. #1 and #2 represent a line in the right ventricle and the “Coumadin ridge,” respectively. #3 and #4 point to accumulation of fatty tissue in the base of the atrial septum and tricuspid valve annulus, respectively. Fatty tissue in the tricuspid valve annulus has often been mistaken for a tumor. (LA: Left atrium; LV: Left ventricle; RA: Right atrium; RV: Right ventricle).
