Coronary occlusion

Korean Circulation Journal

The retrograde approach through a collateral artery is now thought to improve the success rate of percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO), and different kinds of strategies for this technique have been developed. However, the basic principles of PCI for CTO, such as firm back-up support with a guiding catheter and fine control of the guide wire, should be adhered to more strictly to succeed with this complex procedure. We present a case in which a CTO of the proximal left anterior descending artery was successfully opened by the retrograde approach through a collateral from the left circumflex artery, during which two guiding catheters were simultaneously used in the same coronary artery for the purpose of strong back up support for the retrograde device and fine control for the antegrade device.
