Experimental: Pre-existing bioprosthetic aortic valve
Patients with a history of surgical or transcatheter valve replacement with bioprosthetic valves undergo cardiac contrast CT imaging and transthoracic echocardiography to evaluate structural and functional integrity of the aortic valves. Patients with prosthetic valve abnormalities suggestive of thrombus will be administered anticoagulation therapy with Vitamin K antagonists (Warfarin) for 3 months with goal INR 2-3, followed by repeat contrast CT of the chest and transthoracic imaging. Repeat imaging following 3 months of anticoagulation therapy is performed to evaluate the response to anticoagulation therapy.
