Hybrid procedure for obstructive neonatal left ventricular tumors.

We report the use of the hybrid procedure (bilateral pulmonary artery banding, ductal stenting followed by balloon atrial septostomy) in the first week of life for the treatment of two neonates with large left ventricular fibromas resulting in univentricular physiology. At 6 months of age, second-stage palliation was accomplished and the 2 patients are growing well with normal developmental milestones and no atrial or ventricular ectopy at 30 months. Hybrid strategy offers a less invasive, initial intervention and the options of typical second-stage univentricular palliation, conversion to biventricular physiology in cases of tumor regression, planned surgical resection, or transplantation.
