OBJECTIVE: To describe our experience with repair of coarctation of the aorta in adults using left heart bypass.
METHODS: From November 2007 to October 2009, eight adult patients with coarctation of the aorta underwent surgical repair under circulatory support using a left atrium to femoral artery bypass circuit, with graft interposition tube through left posterolateral thoracotomy. Five patients were female, with mean age of 31.5 ± 13.1 years. All patients had hypertension and others associated cardiovascular diseases.
RESULTS: There were no deaths or neurological complications. The mean surgical time was 308 minutes with mean left heart bypass and distal aortic clamping time of 73 and 65 minutes respectively. Postoperative bleeding was 696 ml in average. Six patients developed severe hypertension postoperatively requiring intravenous vasodilators. The mean length of stay was 9 days. A significant reduction of gradient blood pressure occurred. Echocardiographic follow-up up to two months postoperatively showed mean aortic / graft gradient of 20.3 mmHg.
CONCLUSION: In this series the use of left heart bypass showed to be a safe option in the surgical correction of coarctation of the aorta in adults, especially in patients with abnormal aortic wall. There was no spinal cord ischemia in the cases studied.
