| Abstract: | We report two successful cases with a new percutaneous coronary intervention (PCI) technique to treat chronic total occlusion (CTO) by using contra‐lateral coronary angiography with a single guiding catheter (GC) safely. Firstly, a GC was inserted into the coronary artery supplying collaterals and a microcatheter was inserted into the distal side of the coronary artery. Then, the GC was retroflexed and engaged in the targeted coronary artery with CTO. While the contra‐lateral coronary artery was visualized by injection through a microcatheter, a guide wire was controlled and passed through the CTO lesion. Two sheaths insertion were necessary to perform contra‐lateral angiography in CTO PCI. This new technique makes it possible to perform safe contra‐lateral angiography with a single sheath and a single GC. It could reduce vascular access complication rates. © 2015 Wiley Periodicals, Inc. |
