Submitral left ventricular aneurysm most commonly occurs among the black population. Nevertheless, this lesion has been described among whites. We report 2 cases of submitral left ventricular aneurysm that we treated successfully by surgery. Case 1 is that of a 52-year-old Brazilian black man with a submitral left aneurysm and mitral incompetence. Case 2 is that of a 25-year-old white man with a history of recurrent stroke; his echocardiographic study showed a small submitral left ventricular aneurysm. Due to the growing incidence of submitral left ventricular aneurysm among the white population, we emphasize the importance of a targeted echocardiographic study in all patients with a history of embolic episodes in the absence of apparent risk factors for embolism.

二尖瓣下左心室动脉瘤最常见于黑人人群。然而，这种病变在白人中也有描述。我们报告2例经手术成功治疗的二尖瓣下左心室动脉瘤病例。病例1是一名52岁的巴西黑人男性，患有二尖瓣下左动脉瘤和二尖瓣关闭不全。病例2是一名25岁的白人男性，有复发性中风病史；他的超声心动图检查显示有一个小的二尖瓣下左心室动脉瘤。由于二尖瓣下左心室动脉瘤在白人人群中的发病率不断上升，我们强调对于所有有栓塞发作史且无明显栓塞危险因素的患者进行针对性超声心动图检查的重要性。
