Patients with pulmonary atresia with a ventricular septal defect are often palliated with a right ventricle to pulmonary artery conduit. Pulmonary artery interventions can result in the development of stenosis, and less commonly, atresia. We describe a novel case where an 11-month-old infant male with pulmonary atresia, ventricular septal defect, and bilateral branch pulmonary artery stenosis developed discontinuity of the left pulmonary artery, and was successfully recanalized with radiofrequency perforation and stent angioplasty, after a failed attempt at an intraoperative stent implantation.

Pulmonary arteriovenous malformations are a rare entity in children, and can cause significant morbidity. Device embolization has become the intervention of choice over the past 2 decades as more sophisticated devices have become available. We present an adolescent with a single, large arteriovenous malformation diagnosed and treated as part of an international medical mission in Kampala, Uganda, highlighting the atypical diseases encountered in developing countries and treatment modalities that can be employed.
