SummaryWe describe the case of a 59-year-old male. His first percutaneous coronary intervention (PCI) using a bare metal stent was performed for a 90% stenosis in the mid portion of the left anterior descending artery (LAD). However, we performed re-PCI because in-stent restenosis developed during a chronic stage. After the first dilatation of the restenotic lesion, using a cutting balloon, the stenosis at the ostium of the septal branch, which takes off from the stent strut, became exacerbated. Therefore, after selective guidewire insertion to the septal branch, we performed balloon inflation. Unfortunately, a coronary dissection and perforation developed in the septal branch and a coronary arteriovenous shunt was also formed. Additional inflation for in-stent restenosis with a perfusion balloon provided successful occlusion of the ostium of the septal branch and the shunt flow disappeared. After careful re-selection of a guide wire into the septal branch, the perforated portion was then dilated using a small-sized conventional balloon. Finally, reperfusion of the septal branch was accomplished without any angiographic sign of coronary dissection, perforation or shunt. We herein report a rare case of coronary arteriovenous shunt formation due to the dissection and perforation of a coronary artery.
