title: Percutaneous coronary intervention and subsequent endovascular beta-radiation brachytherapy in a 14-year-old with repaired anomalous left coronary artery from pulmonary artery.
abstract: Anomalous origin of the left coronary artery from pulmonary artery (ALCAPA) is a rare congenital anomaly. Re-establishment of the dual coronary system is the standard treatment, although the long-term outcome after surgical repair is not well defined. We report a case in which coronary stenting was performed to treat left anterior descending artery lesions eight months after surgical repair of ALCAPA. The patient then developed rapid in-stent restenosis within three months, which was successfully treated by rotational atherectomy, balloon angioplasty, and catheter-based beta-radiation brachytherapy. Follow-up angiograms after three and six months showed no recurrent in-stent restenosis. This represents the first report of coronary stenting in the setting of ALCAPA, and the first report of catheter-based intracoronary radiation therapy in a pediatric patient.
