Abstract:
We describe an extremely rare case of a 37-year-old female patient who presented with exertional angina and was diagnosed with a unique coronary anomaly with an anomalous right coronary artery with origin in the left anterior descending artery and a fistula between this anomalous coronary artery and the pulmonary artery.
Learning Objectives:
Most patients with coronary anomalies are asymptomatic but some may have angina caused by a coronary steal phenomenon, myocardial infarction, or even sudden death depending on the circuit and characteristics of the anomaly.The combination of multiple coronary anomalies is extremely rare.Despite being a rare diagnosis, coronary anomalies should always be considered as a cause of myocardial ischemia, especially in young patients with low probability for coronary obstructive disease.
