Abstract
Non-obstructive transcatheter heart valve (THV) thrombosis as a potential mechanism after stroke after transapical transcatheter aortic valve replacement (TAVR) is demonstrated by the present case report. By performing cardiac computed tomography (CT) in addition to standard transthoracic echocardiography (TTE) follow up after TAVR, it has been shown recently that non-obstructive THV thrombosis may be more common than previously anticipated. However, the clinical implications of non-obstructive THV thrombosis remain unclear. In the present patient, post-TAVR TTE and transeophageal echocardiography demonstrated normal THV function, and showed no evidence of THV thrombosis. In contrast, cardiac CT revealed findings consistent with THV thrombosis. The patient subsequently developed acute ischemic stroke that was treated with thrombolysis. Follow up cardiac CT and echocardiography demonstrated complete THV thrombus resolution.
