Atypical origin of the left coronary artery originating from the right coronary sinus with interarterial course: A case report

A left coronary artery with atypical origin originating from the right coronary sinus with interarterial course was found in a 68-year-old man, who had been referred to the hemodynamics unit for ventricular extrasystoles, observed on ECG, which raised suspicions of suspect coronary heart disease.

Description
Summary:	A left coronary artery with atypical origin originating from the right coronary sinus with interarterial course was found in a 68-year-old man, who had been referred to the hemodynamics unit for ventricular extrasystoles, observed on ECG, which raised suspicions of suspect coronary heart disease. Atypical origin was observed on a coronary angiography, and interarterial course was confirmed with a coronary CT. The left coronary artery is observed arising from the right aortic sinus, in an ostium separated by 5 mm to the left of the right ostium. The left coronary trunk was 28 mm long, with eccentric calcium plaque in the distal third of the coronary trunk, and 50% stenosis. The right coronary artery was of normal caliber. Atypical origin of the left coronary artery is a rare condition, normally associated with sudden death. •A left coronary artery with abnormal origin originating from the right coronary sinus with interarterial course was found in a 68-year-old man.•The left coronary artery is observed arising from the sinus of Valsalva right, in an ostium separated by 5 mm to the left of the right ostium. Left coronary trunk 28 mm long.•The left coronary artery with interarterial course is considered a rare anomaly and is associated with sudden death.•Studies indicate that coronary artery embryology depends on vasculogenesis and possibly has genetic determinants.
