摘要

左心室假性瘤對於主動脈瓣置換術而言，是一種罕見的併發症。而因為左必室假性瘤壓迫冠狀動脈而產生狹心症的情形更是少見。在此，報告一個病例是一位六十歲的男性，他因為主動脈瓣窄縮而曾經接受過人工主動脈金屬瓣膜置換術。然因為主動脈瓣心內膜炎併發膿瘍形成，而施行再一次的主動脈瓣置換及膿瘍清除併薄膜修補。一，這位病患產生狹心症及心衰竭的症狀。檢查發現在左心室外流出口處有一假性瘤，而且會在心臟收縮及早期舒張期壓迫左冠狀動脈而造成狹心症。這位病患接受再一次的瓣膜置換及薄膜修補後，狹心症的症狀就完全消失。

Left ventricular pseudoaneurysm is an unusual complication of aortic valve replacement. Angina pectoris due to coronary compression by the pseudoaneurysm is extremely rare. We report a case in which the patient received a second aortic valve replacement because of infective endocarditis complicated by abscess formation. This 60-year-old man developed angina pectoris and heart failure one year after the operation. A left ventricle outlow tract pseudoaneurysm with compression of the left coronary arteries in the systolic and early diastolic phases was found. A third aortic valve replacement and a patch repair of the aneurysm were performed and the symptoms of angina and heart failure subsided after surgery.
