First-stage angioplasty for a single ventricle with pulmonary artery coarctation

We report first-stage palliation consisting of pulmonary artery angioplasty and a systemic-to-pulmonary shunt using a minimized cardiopulmonary bypass technique performed with modified ultrafiltration for two patients with a single ventricle, pulmonary atresia, patent ductus arteriosus, and pulmonary coarctation during early infancy. Postoperative early extubation (15 and 18 h) and bilateral pulmonary artery growth before the second stage (Nakata indexes, in mm²/m²: right 94, left 53; and right 209, left 70) were experienced. Less-invasive pulmonary artery continuity reconstruction at an early stage is advantageous for low-weight patients with a single ventricle and pulmonary coarctation.
