Determinants of Adverse Outcomes After Systemic-To-Pulmonary Shunts in Biventricular Circulation

Abstract

Background Systemic-to-pulmonary shunts are useful palliative procedures, although many teams have been deterred by high mortality and morbidity. We aimed to identify predictors of adverse outcomes after shunts in biventricular lesions. Methods From 2004 to 2014, 173 children had shunt procedures. Morphologies included: tetralogy of Fallot, pulmonary atresia with ventricular septal defect (VSD) with and without major aortopulmonary collaterals (MAPCAs), transposition of great arteries with pulmonary stenosis, and double outlet right ventricle. Median age was 22 days (range, 3 to 3,438 days) and median weight 3.2 kg (range, 1.7 to 20 kg). Shunt sizes ranged from 3 to 5 mm with median shunt si..
