The Bentall procedure is a surgical technique for an ascending aortic or aortic aneurysm in combination with valve disease. A well-known uncommon complication of after the Bentall procedure is coronary artery stenosis related to coronary anastomosis of an interposed graft. We report on a 73-year-old woman who presented with heart failure secondary to graft stenosis of the right coronary artery 6 months after undergoing a modified Bentall procedure. Percutaneous coronary intervention (PCI) was performed and type II coronary artery perforation occurred during PCI of the right coronary artery. We used a perfusion balloon and achieved hemostasis successfully. We report a case of coronary artery perforation that was treated with perfusion balloon during PCI in a patient with a prior modified Bentall procedure. In addition, we present a case series of PCI for ostial coronary stenosis after the Bentall procedure.
