Hybrid Right Ventricular Outflow Stent Insertion in a Small Neonate with Muscular Pulmonary Atresia with Intact Ventricular Septum: A Case Report.

Pulmonary atresia with intact ventricular septum (PAIVS) is a rare congenital heart disease that often needs a critical decision on whether to open the right ventricular outflow tract (RVOT). Significant morbidity and considerable mortality might preclude the safe use of percutaneous or surgical right ventricular decompression in patients with muscular PAIVS. We report the case of a 21-day-old neonate weighing less than 3 kg who underwent hybrid RVOT stent insertion as initial palliation for muscular PAIVS and subsequent anatomical correction at 5 months of age, with 6 years of follow-up.
