Abstract

Coronary arteries arising from single coronary sinus is a rare congenital anomaly. We report a 30-year-old male who presented with atypical chest pain and computed tomography coronary angiography revealed a solitary coronary artery originating from a single ostium in the right sinus of Valsalva.

Highlights

Solitary coronary artery is a coronary artery anomaly that describes the origin of both right coronary artery (RCA) and left coronary artery (LCA) from a single aortic sinus
A single coronary artery arising from one aortic sinus is an extremely rare congenital anomaly that is seen in only 0.0024%–0.044% of the population.[2,3]
We report a case of a single coronary artery arising from the right coronary sinus of Valsalva, in a 30-year-old man who presented with atypical chest pain

Summary

Introduction

Solitary coronary artery is a coronary artery anomaly that describes the origin of both right coronary artery (RCA) and left coronary artery (LCA) from a single aortic sinus. We report a case of a single coronary artery arising from the right coronary sinus of Valsalva, in a 30-year-old man who presented with atypical chest pain. Case Report A 30-year-old male presented with recurrent left sided chest pain that was non-radiating He was a smoker with no history of hypertension, diabetes mellitus or family history of coronary heart disease. Exercise treadmill test was negative for inducible myocardial ischemia Since he had several episodes of chest pain, multislice computed tomography (MSCT) coronary angiography was performed to rule out coronary artery disease. Left anterior oblique (Fig. 1b) views we saw a single coronary artery arising from the right sinus of Valsalva trifurcating into RCA, left anterior descending (LAD) artery and left circumflex (LCx) artery. Right anterior oblique (Fig. 1a) and left anterior oblique (Fig. 1b) views show a solitary coronary artery arising from the right sinus of Valsalva trifurcating into right coronary artery (RCA), left anterior descending (LAD) artery and left circumflex (LCx) artery
