Demonstration of an anomalous connection between the left coronary artery and the pulmonary artery using a multislice CT 64.

In this article, we describe two cases of anomalous connection of the left coronary artery. The first case is an infant of 4 years with an anomalous origin of the left anterior descending (LAD) artery and the diagonal branches and a circumflex artery which originated from the pulmonary artery. The second case is an adult of 50 years with the coronary artery originating from the pulmonary artery. Anomalous origin of the left coronary artery from the pulmonary artery is an uncommon congenital cardiac anomaly with an incidence of 0.25% among all congenital heart defects (Parale and Pawar [2006], J Assoc Physicians India 54:397-399). The originality of this communication consists in the use of a multislice CT scanner as a support for the angiography. The result is an original image with three dimensional details; in the case of the infant, it was determinant in the choice of the surgical approach.
