Proximal Anomalous connections of the coronary arteries (ANOCOR) are rare and their association with Acute Coronary Syndrome (ACS) is even rarer.

We report the case of a patient who had an acute coronary syndrome with a ST Segment Elevation Myocardial Infarction (STEMI) of atherosclerotic origin with a proximal anomalous connection of the left anterior descending artery and of the circumflex artery, both arising from the antero-right sinus. We opted for angioplasty first of the right coronary artery which was responsible for the myocardial infarction, and secondarily of the circumflex artery after eliminating a high-risk path for sudden death.
