Bland White Garland syndrome or  (ALCAPA) is a congenital anomaly of the heart’s arterial supply in which the left coronary artery arises from the pulmonary artery. Worldwide its incidence is believed to be 1/3,00,000 live births. The part of the left ventricle which is supplied by this artery is thin, scarred and dilated and is a cause of myocardial ischemia in children. It is usually an isolated congenital anomaly. Sometimes it might be associated with patent ductusarteriosus, ventricular septal atrial septal defect murmur defect, tetralogy of fallout or coarctation of the aorta. The cause of myocardial ischemia in this condition is not due to the perfusion by deoxygenated blood or due to a single normally functioning coronary artery i. e. the right coronary artery, but is due to the direction of blood flow through the coronary bed. Owing to the increased pulmonary arterial pressures, in the fetal and early neonatal life, there is antegrade flow into the anomalous coronary artery from the pulmonary artery.
