Postoperative images. (A) Post-operative enhanced chest CT scan shows neo-ostium (black asterisk) from the right sinus of Valsalva in patient 1. (B) Post-operative contrast-enhanced CT scan shows the anomalous RCA shared the same sinus with the left coronary system (white asterisk), with its attenuated proximal portion passing between the aorta and pulmonary trunk in patient 2. This image also shows that RGEA was bypassed to the distal RCA. (C) Post-operative three-dimensional volume rendering of contrast-enhanced CT scan in patient 3. Chest CT scan revealed that the ascending aorta and part of the aortic arch were replaced with a prosthetic graft, and that the innominate artery was bypassed using a side-arm branch. Also the left internal thoracic artery to the proximal right coronary artery bypass was patent. (CT: computed tomography; AO: aorta; LMC: left main coronary artery; PA: pulmonary artery; RCA: right coronary artery; LITA: right internal thoracic artery; RGEA: right gastroepiploic artery).
