A rare coronary artery anomaly: origin of all three coronary arteries from the right sinus of valsalva

Lale Pasaoglu et al. J Clin Imaging Sci. .

Abstract

Left anterior descending (LAD) artery and left circumflex (LCx) coronary artery originating separately from the right sinus of valsalva is exceptionally rare and very few cases have been reported in the literature. Congenital coronary artery anomalies are generally incidental, uncommon, and asymptomatic. Some can cause severe potentially life-threatening symptoms such as myocardial ischemia and sudden cardiac death. The aberrant vessels that pass between the aorta and the pulmonary trunk pose a risk of sudden cardiac death, particularly if the vessel supplies the left coronary artery network. The electrocardiographically gated multi-detector computed tomography (MDCT) allows accurate and non-invasive depiction of coronary artery anomalies including origin, course, and termination. We report here a rare case of all three coronary arteries separately originating from the right coronary sinus, which was detected with MDCT.

Keywords: Anomalies; coronary artery; multidedector computed tomography.

56-year-old male patient admitted with chest pain diagnosed with three coronary arteries originating separately from the right coronary sinus. Axial oblique maximum intensity projection image shows left anterior descending artery (short white arrow), right coronary artery (open arrow), and left circumflex artery (long white arrow) – three coronary arteries originating from the right coronary sinus.

56-year-old male patient admitted with chest pain diagnosed with three coronary arteries originating separately from the right coronary sinus. (a) Volume-rendered three-dimensional image (VR-3D) shows the left anterior descending artery (LAD) originating from the right coronary sinus (short white arrow) and passing between the aorta (Ao) and the pulmonary artery (Pa) (open arrow: right coronary artery). (b) MDCT image shows LAD diagonal branch with myocardial bridging (arrowheads).
