title: Single left coronary artery with origin of the right coronary artery from distal circumflex.
abstract: We report two very unusual cases of agenesis of the right coronary ostium with continuation of the left circumflex artery as the right coronary artery. The recognition of the anomaly in the first case lead to a better understanding of this finding in the second case, which translated into shorter procedure time, less contrast volume, and fewer catheter manipulations.
