Anomalous Coronary Arteries: A Case of Rare and Incidental Findings

Mihir Odak, Ndausung Udongwo, Dhaval Desai, Matthew Schoenfeld


Anomalous coronary artery from the opposite sinus (ACAOS) is an uncommon, yet highly variable anatomical abnormality. These coronary anatomy variants are often discovered incidentally during cardiac catheterization. These variants can be challenging intraoperatively and require adjustment by the operator. We present the case of a 93-year-old female who presented for shortness of breath due to severe mitral regurgitation (MR), who was found to have an anomalous left main coronary artery (LMCA) from the right sinus of Valsalva (RSOV). This asymptomatic finding was managed conservatively and patient underwent successful MitraClip treatment.
