The Suitability of Percutaneous Transradial Coronary Intervention for Chronic Total Occlusion (CTO) – An Experience at PIC.
Ann King Edward Med Uni Jan ;17(4):356-61.

Background: Intervention of chronic total coronary artery occlusion is quite challenging. The usual vascular route used in PCI for CTO in most cardiac catheterization laboratories is through femoral artery. In this study we evaluated the feasibility of transradial coronary intervention in CTO. Study Design: Interventional descriptive study. Place and Duration of Study: Department of cardiac catheterization and interventional cardiology of Punjab Background: Intervention of chronic total coronary artery occlusion is quite challenging. The usual vascular route used in PCI for CTO in most cardiac catheterization laboratories is through femoral artery. In this study we evaluated the feasibility of transradial coronary intervention in CTO. Study Design: Interventional descriptive study. Place and Duration of Study: Department of cardiac catheterization and interventional cardiology of Punjab tapered occlusion and occlusion of less than 15mm. The main cause of failure was failure to pass guide wire in 44 (81.48%). In 10 cases, PCI was crossed over to femoral artery due to poor guiding catheter support, subclavian / radial artery tortuousity. Procedure related complications occurred in 6 cases with coronary artery dissection in 4 cases and perforation in 2 cases. Conclusion: The transradial approach is suitable vascular route in coronary interventions for CTO with the use of newer PCI equipments.
