A major concern regarding transcatheter aortic valve replacement (TAVR) is leaflet thrombosis. Four-dimensional computed tomography (4D-CT) is the preferred imaging modality to evaluate patients with suspected valve thrombosis. To date, the abnormal findings visualized by 4D-CT suggestive of leaflet thrombosis have lacked pathologic confirmation from a surgically explanted valve in a surviving patient. Herein, we provide pathologic confirmation of thrombus formation following surgical explantation of a thrombosed TAVR prosthesis that was initially identified by 4D-CT.
经导管主动脉瓣置换术（TAVR）的一个主要问题是瓣叶血栓形成。四维计算机断层扫描（4D-CT）是评估疑似瓣膜血栓形成患者的首选成像方式。迄今为止，4D-CT显示的提示瓣叶血栓形成的异常发现，尚未得到存活患者手术取出瓣膜的病理证实。在此，我们提供了一例经手术取出的血栓形成的TAVR假体的病理证实，该假体最初是通过4D-CT识别的。
