Why the study?
The origination of the posterior descending artery from the left anterior descending artery is an extremely rare coronary anomaly that dictates which cardiac intervention should be attempted in ischemic cases.
Highlights an extremely rare coronary anomaly (PDA originating from LAD) and emphasizes the importance of defining coronary anatomy for appropriate cardiac intervention in ischemia.
The prevalence of congenital coronary artery anomalies is approximately 1% in the general population. They are a common cause of sudden death in younger persons. The origination of the posterior descending artery (PDA) from left anterior descending (LAD) artery is an extremely rare anomaly. We present a case of a 54-year-old female who presented with diabetic ketoacidosis with co-existing non-ST elevation myocardial infarction, therefore, had an invasive angiogram that identified the anomalous origin of PDA from LAD. It is vital to define coronary anatomy as anomalies dictate which cardiac intervention should be attempted in cases of ischemia.
