A transesophageal echocardiogram (TEE) offers better picture quality compared to a transthoracic echocardiogram (TTE), particularly of the heart valves. A TEE is commonly performed to evaluate for a thrombus (blood clot), heart valve infection (endocarditis), heart valve dysfunction and diseases of the aorta. It is also often performed to guide heart surgery.
An implantable cardioverter defibrillator (ICD) is used to treat life threatening fast heart rhythms. On this page, I have included videos as well as links to information about ICDs as well as compared them with pacemakers.
