NSTEMI in 50-year-old Filipino Male with an Absent Left Main Coronary Artery and Left ACAOS with Intraarterial Course: A Very Rare Encounter

Coronary artery anomalies are extremely uncommon occurrences. Encountering a combination of an absent left main coronary artery (LMCA) and a left anomalous origin of the coronary artery from the opposite sinus of Valsalva (ACAOS) is an exceptionally rare phenomenon. In this report, we present a case of a 50-year-old Filipino male who was diagnosed with a congenital absence of the LMCA and left ACAOS with an interarterial course, and subsequently experienced a non-ST elevation myocardial infarction (NSTEMI).
