Abstract :
The left and right coronary arteries play a crucial role in the perfusion of heart. These arteries are situated between the epicardium and myocardium. Typically, the left coronary artery bifurcates into anterior descending artery and circumflex artery. However, during a routine dissection of one of the cadavers, we observed the trifurcation of the left coronary artery, which was traced as median aka intermediate artery which arises as one of its main branches. We also noticed variation in right coronary artery which had very prominent conus branch originating after the right coronary artery arising from right aortic sinus. Materials and methods: Routine dissection was conducted on a 72 year old male cadaver. Conclusion and results: Variant branches of coronary artery noted. Many a times these variations are asymptomatic and cause no distress but knowledge about variation has vital role in treatment and diagnosis of various cardiac illness.
