Postoperative coronary artery complications after Bentall procedures are well recognised but are rare and potentially fatal. There have been only five cases documenting percutaneous coronary intervention (PCI) for right coronary artery (RCA) involvements after button Bentall procedures. We describe a case of postoperative silent myocardial ischaemia in a 72-year-old man who underwent the button Bentall procedure for a right sinus of Valsalva aneurysm. On postoperative day 15, an RCA complication was incidentally detected by follow-up multidetector CT. Coronary angiography showed proximal RCA kinking, which was not an anastomosis but a native coronary artery. The patient underwent a successful PCI with drug-eluting stent implantation. We reviewed six cases consisting of this case and five previous cases treated with PCI. These cases enhance the recognition of potential RCA complications after the button Bentall procedure.
