One-Stage Midline Unifocalization and Anatomic Correction of Corrected Transposition With Pulmonary Atresia and Absence of Central Pulmonary Arteries

A concomitant double-switch procedure and unifocalization were performed in a child with congenital corrected transposition of the great arteries, ventricular septal defect, pulmonary atresia, absence of central pulmonary arteries and major aortopulmonary collateral arteries. Predischarge echocardiography showed no residual shunts with laminar flow in baffles and outflow tracts. Follow-up computed tomographic angiography revealed good neo-main pulmonary artery confluence with satisfactory pulmonary blood flow.
