The Origin of The Posterior Descending Artery from the 1st Septal Perforator: A Rare Anomaly

Abstract

The origin of the posterior descending artery [PDA] from the left anterior descending artery [LAD] or its branches is a rare coronary anomaly. The critical coronary lesions before the origin of the PDA in this circumstance can lead to large ischemia or infarction, which can be fatal. Coronary angiography is the investigation of choice. These patients should undergo early revasculazation.
