Abstract
An 84-year-old man presented to our hospital with congestive heart failure. Coronary angiography was performed that indicated single coronary artery and the complicated triple vessel disease. The angiography showed that the coronary artery originated from a single ostium in the right sinus of Valsalva, and divided into 3 branches: the right coronary artery, left anterior descending (LAD) artery, and left circumflex artery (LCA). The coronary artery did not branch out into the left main. The LAD was anterior to the great vessels, whereas the LCA passed alongside the great vessels. We performed an on-pump beating-heart coronary artery bypass grafting, and his postoperative course was uneventful.
