Percutaneous closure of anomalous left coronary artery from pulmonary artery rare procedure in desperate situation: case report.

Background: When anomalous left coronary artery from the pulmonary artery is diagnosed in infancy, it is associated with high mortality, but collaterals permit rare adult survival despite coronary steal. We report normalisation of perfusion abnormality after transcatheter proximal left coronary occlusion in a symptomatic adult with inducible ischaemia.

Methods: A forty-eight-year-old female presented with exertional chest pain; EKG showed sinus rhythm with left axis deviation with intraventricular conduction defect.
