1. The anatomy of hypoplastic left heart syndrome with underdeveloped left ventricle (LV).
The anatomy of hypoplastic left heart syndrome with underdeveloped left ventricle (LV). The arrow indicates the atrial septum defect. B. Stage 1 palliation using a modified Blalock-Taussig shunt (MBTS). C. Stage 1 palliation using a right ventricle (RV)–to–pulmonary artery (PA) conduit (Sano modification). D. Stage 2 palliation using the bidirectional Glenn shunt. It is a direct anastomosis of the superior vena cava (SVC) to the right PA (RPA). E. Stage 3 palliation. The extracardiac Fontan uses a tube graft to connect the inferior vena cava to the central PA. Ao=aorta, LA=left atrium, LPA=left pulmonary artery, MPA=main pulmonary artery, PDA=patent ductus arteriosus, RA=right atrium.
