Echocardiographic studies were used to diagnose a thrombus adherent to the ventricular surface of a stent-mounted porcine aortic heterograft valve in the mitral position. Multiple, intense, irregularly thickened echoes were present within and behind the anterior and posterior heterograft valvular stent. This suggested the presence of adherent biologic material, such as a thrombus. The abnormal echocardiographic findings are compared to the findings in a normally functioning porcine heterograft aortic valve in the mitral position.
超声心动图研究用于诊断二尖瓣位猪主动脉带支架异种移植瓣膜心室面附着的血栓。在前、后异种移植瓣膜支架内及后方存在多个强烈、不规则增厚的回声。这提示存在附着的生物物质，如血栓。将异常超声心动图表现与二尖瓣位正常功能猪异种移植主动脉瓣膜的表现进行比较。
