Anomalous origin of the left main coronary artery in a 62‑year‑old woman: a case report and review of the literature.

Abstract

Introduction: Abnormalities of the coronary arteries, including abnormal origins, are often detected in heart patients who undergo coronary angiography. Although only a small percentage of these abnormalities lead to serious complications, the consequences can be extremely fatal.

Case presentation: We report the case of a 62-year-old woman who presented with chest pain. The patient has a history of hypertension and complains of chest pain that worsens with walking and improves with rest. A basic electrocardiogram (ECG) showed sinus rhythm with no signs of arrhythmia or ischemic changes. Coronary angiography revealed an anomalous left coronary artery originating from the right sinus of Valsalva (RSoV).

Conclusions: We report a rare case of an anomalous left coronary artery originating from the RSoV without specific clinical symptoms. The patient presented with unstable angina, and after further investigation, this anomaly was diagnosed. Investigating these abnormalities, especially in young individuals with cardiac symptoms, should be prioritized. Cardiologists should also be aware of this rare condition that can have fatal consequences.
