Anomalous Left Coronary Artery from the Right Pulmonary Artery

Camille-Marie Go-Cacanindin

 

In the most common form of ALCAPA, the abnormal coronary artery arises from the adjacent pulmonary valvar sinus, rather than the pulmonary trunk. In this case, the Anomalous Left Coronary Artery originated the Right Pulmonary Artery. Such case has an incident of 1 in 2,000,000 live births. This is the first reported case in a tertiary cardiovascular referral center.  In fetal life, this has no detrimental effect since pressures and saturations are similar in the aorta and pulmonary artery. After birth, however, the pulmonary artery contains desaturated blood at pressures that rapidly fall below systemic pressures. The left ventricle is perfused with desaturated blood at low pressures leading to infarction with ventricular dysfunction. Coronary translocation and Lecompte maneuver was done which provided relief for the patient’s condition.
