Abstract

Left ventricular outflow tract obstruction in patients with pulmonary atresia with intact ventricular septum has been rarely reported. Data are lacking on the impact and management of systemic ventricular outflow tract obstruction that developed following the Fontan procedure. We report a case of an 8-year-old male who developed left ventricular outflow tract obstruction 6 months after the Fontan procedure.
