Abstract: Introduction: the management of small infants with tetralogy of Fallot with pulmonary atresia and hypoplastic pulmonary arteries can be very challenging. Methods: In 3 small infants (weight range 2200-3600 g, pulmonary trunk 2.0-3.2 mm), initial palliation consisted of sternotomy, transventricular puncture of the right ventricular outflow tract and atretic pulmonary valve, followed by balloon dilation (n=1) or stent deployment (n=2) from the right ventricle into the pulmonary trunk (stent diameter 5-6 mm, length 16 mm). Results: The procedure resulted in adequate palliation with good anterograde flow to the pulmonary arteries and near normal saturations in all 3 patients (> 92%); there was no associated morbidity. Additional transvenous stenting was required in all patients because of progressive muscular infundibular stenosis after a median of 3 months. Two patients evolved to full repair at the age of 5 months and one patient with multiple hilar stenoses requires additional percutaneous procedures through the stented RV outflow tract. Conclusion: Transventricular balloon dilation and stenting of the RVOT through medial sternotomy as initial palliation strategy appears a safe and well tolerated alternative treatment in small infants with tetralogy of Fallot with pulmonary atresia and a hypoplastic pulmonary trunk. © 2012 Wiley Periodicals, Inc.
