Abstract A 58-year-old woman presented with a 2-week history of acute dyspnea in the setting of subtherapeutic warfarin anticoagulation (international normalized ratio, 1.7 on admission) with a history of previous St. Jude bileaflet aortic valve replacement (AVR) 5 years previously. Transthoracic echocardiography revealed severe elevation of the prosthetic aortic transvalvular gradient (peak velocity, 5 m/s; peak gradient, 125 mm Hg) with severe eccentric aortic regurgitation. The morphology of the prosthetic aortic valve was not clearly visualized secondary to an acoustic shadow from the metallic prosthesis. The patient was referred to cardiac computed tomography (CT) for further evaluation of prosthetic dysfunction and to exclude coronary artery disease in case surgical intervention was required.
