title: Spontaneous partial regression of coronary artery fistula following optimal medical therapy in a patient who had combined significant coronary artery spasm.
abstract: Coronary artery fistulas (CAFs) are one of the most rare cardiac anomalies. Some patients with CAF may suffer from ischemic chest pain that originates from combined significant coronary artery spasm (CAS). Spontaneous regression of CAF has been reported in a few cases, almost all of which were infants. We report an adult patient who presented with ischemic chest pain due to multiple coronary arteries to pulmonary artery fistulas and combined significant CAS induced by intracoronary acetylcholine provocation test. Spontaneous regression of one of the fistulas was observed at 2-year angiography follow-up.
