Double outlet right ventricle (DORV) is a congenital heart disease in which the great arteries (aorta and main pulmonary artery) arise from the right ventricle (RV), with concomitant ventricular septal defect (VSD), usually non-restrictive. Double outlet right ventricle can be accompanied by other cardiovascular anomalies, such as ventricular hypoplasia, restrictive septal defects and various pulmonary vascular bed anomalies, including hypoplastic pulmonary arteries (PA).Critical right ventricle outflow tract (RVOT) stenosis and hypoplasia of pulmonary arteries in newborns with DORV necessitates the need to maintain pulmonary blood flow to provide optimal systemic oxygenation in severely cyanotic newborns. Routinely recommended treatment for cyanotic newborns is a surgical procedure with implantation of a Blalock-Taussig systemic-to-pulmonary artery shunt (BT shunt), or interventional patent arterial duct (PDA) stenting. In complex RVOT stenosis with hypoplastic pulmonary arteries alternative percutaneous multilevel RVOT and pulmonary trunk stenting could serve as an alternative treatment [1, 2].We report multistage treatment of a hypotrophic infant suffering from DORV with RVOT stenosis and a hypoplastic pulmonary vascular bed. Initial diagnostics with angiography revealed multilevel obstruction of the RVOT with severe hypoplasia of pulmonary arteries. The baby, who presented severe cyanosis, did not meet anatomic criteria for surgical palliation while the ductal flow remained insufficient. Her initial morphology determined our alternative strategy with initial RVOT stenting, despite the hindrance caused by extremely low body weight.
