Abstract
Observing anomalies in the origin of the coronary arteries is a rare but recognised
scenario during coronarography. All the major coronary arteries originating from
the right sinus of Valsalva is an extremely rare anomaly, its reported incidence
being 0.008% in angiographic studies. Most coronary artery variations are benign
and are therefore found accidentally or postmortem. However, some anomalies
in the origin of the coronary arteries are associated with myocardial ischaemia
and a higher risk of sudden cardiac death.
Herein, we report a sporadic case of anomalous origin of the coronary arteries, in
which the right coronary artery, anterior interventricular artery and left circumflex
artery arise separately from the right sinus of Valsalva, each originating from
a separate ostium.
Regardless of their low incidence rate, coronary artery anomalies can cause serious
technical challenges during coronary angiography and percutaneous interventions
because of the unusual location and course of the artery. Echocardiography,
computed tomography, and magnetic resonance imaging can be useful in such
cases.
