Anatomic Risk Factors for Reintervention After Arterial Switch Operation for Taussig-Bing Anomaly

BackgroundThis study aimed to determine the factors related reintervention, especially for pulmonary stenosis (PS), in patients with Taussig-Bing anomaly (TBA) after arterial switch operation.MethodsThis retrospective included 34 TBA who underwent operation between 1993 and 2018. Preoperative anatomic physiologic differences long-term outcomes were determined using a case-matched control transposition of great arteries ventricular septal defect an anterior rightward aorta.ResultsAt operation, median age was 43 days (range, 16 102) body weight 3.6 kg 2.8 3.8 kg). Aortic arch obstruction coronary anomalies present 64% 41% patients, respectively. The hospital mortality rate 11%, including one cardiac death, late 2.9%. Furthermore, 26 reinterventions PS. Patients undergoing PS-related reintervention had significantly larger native artery aortic annulus size ratio than not receiving (1.69 vs 1.41, P = .02). This only predictor reintervention; it higher group arteries/ventricular group. required more group.ConclusionsRegardless complex anatomy associated anomalies, early survival acceptable. Postoperative PS strongly having valve, suggesting that optimal surgical reconstruction achieving appropriate aortopulmonary relationship during operation. aorta. At Regardless
