Abstract

Background: Optimal surgical approach for repair of coarctation of the aorta (CoA) remains controversial. This study aimed to evaluate reintervention rates and its predictors by using a strategy of resection with extended end-to-end anastomosis (REEEA) through left thoracotomy. Methods: A retrospective analysis was performed for all patients who underwent isolated CoA repair or simultaneous repair of CoA and ventricular septal defect repair by REEEA between January 2000 and December 2015 at Ann & Robert H. Lurie Children's Hospital of Chicago, Chicago, Illinois. Patients with complex congenital heart disease were excluded. Transverse arch hypoplasia was defined as echocardiographic z-score lower than −2 or by documentation in medical or operative reports. Reintervention was defined as the need for balloon angioplasty or reoperation. Hypertension was defined as antihypertensive medication use or blood pressure greater than or equal to the 95th percentile. Results: A total of 251 patients with median age at repair of 14.6 days met inclusion criteria. Repair was by left thoracotomy in 226 (90%). Follow-up data were available for 186 of 251 patients, with median follow-up time of 5.4 years (range, 0.2 to 15.3 years); 169 (91%) of these patients underwent thoracotomy. There were no early deaths or early reoperations. A proximal transverse arch z-score lower than −4.1 or a distal transverse arch z-score of less than −2.8 was predictive of repair through sternotomy. Only 4 (2%) patients required reintervention (2 patients had balloon angioplasties, 2 had reoperations). Transverse arch hypoplasia was a risk factor for reintervention (p = 0.048), but surgical approach was not (p = 0.35). Late hypertension was identified in only 33 of 186 (18%) patients. Conclusions: Repair of CoA, even with associated transverse arch hypoplasia, by REEEA through left thoracotomy has a low mortality, low reintervention rate, and low incidence of late hypertension.
