Subvalvar left ventricular aneurysm is a rare disease of unknown etiology, that has been described most often in black Africans. A case of Brazilian indian with heart failure and a murmur of mitral regurgitation is reported. The chest x-ray showed a mild bulge in the left cardiac border and two-dimensional echocardiography demonstrated submitral left ventricular aneurysm, confirmed by left ventricular angiography. Surgical treatment consisted of resection of the aneurysm and mitral valvuloplasty. A perforation of the aneurysm, undetected neither by two-dimensional echocardiography nor by angiography was found at surgery.
瓣下左心室动脉瘤是一种病因不明的罕见疾病，最常出现在非洲黑人中。本文报道了一例患有心力衰竭和二尖瓣反流杂音的巴西印第安人病例。胸部X光显示左心缘有轻度膨出，二维超声心动图显示二尖瓣下左心室动脉瘤，经左心室血管造影证实。手术治疗包括动脉瘤切除和二尖瓣成形术。手术中发现动脉瘤有一处穿孔，二维超声心动图和血管造影均未检测到。
