Abstract Multiplane transesophageal echocardiography allows excellent visualization of all cardiac structures and great vessels. The common clinical indications for transesophageal echocardiography are assessment of complications of myocardial infarction, detection of aortic dissection, diagnosis of infective endocarditis and its complications in native and prosthetic valves, determination of embolic source, visualization of cardiac tumors, evaluation of congenital heart diseases, and assessment of critically ill patients. Transesophageal echocardiography is also a valuable adjunctive imaging method during cardiovascular surgery and percutaneous cardiac interventions.
