Left ventricular aneurysms associated with intraoperative venting of the cardiac apex in children.
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.
