Xransradial Coronary Intervention for Chronic Total Occlusion

摘要

Percutaneous coronary intervention (PCI) for chronic total occlusion (CIO) lesions is one of the major challenges in interventional cardiology. Recently, the development of a tool like tapered-tip guidewires or wide-lumen guiding catheters improves the success rate of transradial coronary- intervention (TRI) for CTO lesions (1). We analyzed 196 consecutive patients of CTO, who underwent TRI from 2000 to 2002 in our hospital. Overall lesion success was achieved in 145 patients (74.0%). 121 lesions treated by any kind of coronary artery stents. Follow-up angiography was performed in 102 patients (70.3%) and mean follow-up period was 11.2 month. Among the case of procedure success. 40 patients underwent TLR.
