Abstract:
Objective To assess the efficacy and safety of using a novel channel dilator (the Corsair microcatheter) accompanied with special occlusion guide wires for coronary chronic total occlusion (CTO) recanalization. Methods From 2011 December to 2013 August,we performed 89 cases (the study group) using channel dilator and the new special occlusion guide wires for CTO recanalization. Another 89 CTO lesions treated before using the corsair microcatheter were compared as the control group.We recorded clinical characteristic, outcome of PCI,radiation exposure time, contrast utilization and the procedure time. The MACE rate was monitored during follow up. Results The intracoronary channel dilator accompanied with special occlusion guide wires were inserted into 33 left anterior descending arteries, 17 left circumlfex arteries and 38 right coronary arteries. The success rates of procedure were signiifcantly higher in the study group than in the control group (91% vs. 67.7%, P < 0.05). Procedure and lfuoroscopy time tended to be lower in the study group than in the control group. There were no serious complications related to the catheter and no death case recorded. Conclusions The channel dilator accompanied with special occlusion guide wires may facilitate the conventional approach with a higher success rate in PCI.
