Off pump repair of aortic arch anomalies with concomitant intracardiac defects via anterior approach

Abstract

Background: The authors evaluated the surgical treatment of aortic arch anomalies associated with intracardiac pathologies, through median sternotomy on beating heart without using cardiopulmonary bypass (CPB). Methods: A consecutive series of 10 patients with aortic coarctation were operated upon. Median age at repair was 3.5 months (range, 5 days to 72 months), median weight was 4 kg (range, 2.2 to 30 kg). All aortic obstruction repairs were done via midsternotomy without using CPB and it is used only for repair of intracardiac defects. The aortic reconstruction included resection and end-to-side anastomosis in six patients and pulmonary autograft patch aortoplasty in four patients. Results: There was no operative mortality. Mean follow-up value was 17.6 +/- 8.07 months. There was no restenosis. Conclusion: Most of the aortic coarctation and interrupted aorta type A can be well-treated surgically through median sternotomy without using CPB. Thus, the need for profound hypothermia and circulatory arrest and its potential neurological and other side effects are removed and CPB is reserved only for associated intracardiac defects, if present.
