Left ventricular (LV) apical aneurysms were observed in 16 of 50 (32%) children (average age 8 years) consecutively catheterized after surgical repair of congenital heart disease. The LV apex was vented by a sump during cardiopulmonary bypass in each. The aneurysms varied in size, but were generally small. Average dimensions were 7.5 X 6.8 mm in the anteroposterior projection and 8.9 X 5.7 mm in the left anterior oblique projection. The LV apex wall was thinner in patients with aneurysms than in age- and lesion-matched controls. All of the LV aneurysm patients were asymptomatic during average follow-up of 4 years. Nevertheless, such aneurysms are anticipated to represent a potential source of cardiovascular complications and, when possible, alternate methods for venting the left ventricle are recommended.
在50例先天性心脏病手术修复后连续接受心导管检查的儿童（平均年龄8岁）中，有16例（32%）观察到左心室（LV）心尖部动脉瘤。每例在体外循环期间均通过引流管对左心室心尖进行排气。动脉瘤大小各异，但一般较小。前后位投影的平均尺寸为7.5×6.8毫米，左前斜位投影为8.9×5.7毫米。有动脉瘤的患者左心室心尖壁比年龄和病变匹配的对照组更薄。所有左心室动脉瘤患者在平均4年的随访期间均无症状。然而，此类动脉瘤预计是心血管并发症的一个潜在来源，如有可能，建议采用其他左心室排气方法。
