Case Report: A life-threatening association of coronary anomalies

Anomalous origin of the left coronary artery from the right sinus of Valsalva, even though rare, has been documented well in literature. However the association of this anomaly with coronary fistulae has been rarely reported so far. We report the case of a 76-year-old female who presented to us with exertional dyspnoea. General physical and cardiovascular examination revealed no significant abnormalities. All laboratory investigations were normal. Chest radiograph was normal. Electrocardiogram showed left bundle branch block. Echocardiogram revealed a globally hypokinetic left ventricle with reduced ejection fraction. Coronary angiogram showed anomalous origin of left coronary artery from right coronary sinus along with a small coronary-cameral fistula connecting obtuse marginal artery to left ventricle, there was no significant stenosis of epicardial coronaries. This case report, documents the rare association of an anomalous coronary origin of left coronary artery with coronary fistula.
