The atrioventricular and ventriculoatrial branches of the human coronary arteries in relation to the type of arterial vascularization.
Studies were performed on 130 hearts removed from cadavers of adults of both sexes. The atrioventricular (A-V) and ventriculoatrial (V-A) branches are vessels which supply both the atrial and ventricular walls through the recurrent rami. A-V and A-V branches often form the superficial and deep networks in relation to the right coronary artery and cirumflex branch of the left coronary artery. The described vessels were observed in 7,5% of cases in the right type, in 53,4% of cases in the symmetrical type of arterial vascularization, and in 23% of instances in the left type of arterial supply.
