Key result
Anomalous PDA origin from the first septal perforator exhibits distinct angiographic features.
Why the study?
Recognition and angiographic features of the anomalous origin of the posterior descending artery from the first septal perforator are not well described.
Highlights the angiographic features and clinical recognition of a rare coronary anomaly involving the posterior descending artery and first septal perforator.
We describe a patient with an unusual coronary anatomic variant in which the first septal perforator gives rise to the posterior descending artery. The angiographic features and clinical recognition of this anomaly are reviewed.
