Case Report:
A 68-year-old woman with known EA underwent echocardiography for evaluation of dyspnea. She complained of a 3-mo history of progressive breathlessness, reduced exercise tolerance and increasing leg swelling. She had been diagnosed with EA at the age of 50 years and had been treated successfully with an angiotensin-converting-enzyme inhibitor until 2001, when her symptoms deteriorated. An echocardiogram demonstrated severe tricuspid regurgitation, and she underwent tricuspid valve replacement. Subsequent echocardiography at 6 mo post-procedure demonstrated malfunction of the prosthesis leaflets with fixation throughout the cardiac cycle. On the current admission, a 64-slice cardiac computed tomography (CT) was undertaken to exclude hemodynamically significant coronary disease. It demonstrated no evidence of coronary atherosclerosis, and clearly depicted the characteristic features of EA including an enlarged right atrium and atrialization of the right ventricle. Thrombus was identified lodged between the medial valve flap and the valve ring . Multiphasic cine CT throughout the cardiac cycle demonstrated immobility of the tricuspid valve leaflets. The patient refused redo-valve replacement surgery. Her symptoms remain moderate......
