Abstract:
Objective The aim of this study was to evaluate the safety and efficacy of 135 cm Corsair microcatheter inpercutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) with antegrade approach via radial artery. Methods From June 2010 to February 2014, a total of 81 patients with CTO lesions treated with 135cm Corsair microcatheter (Asahi Intec Co, Japan) and transradial antegrade approach was enrolled in this study. The success rate of CTO-PCI, the rate of Corsair microcatheter crossing the CTO lesions and the number of balloon catheters utilization were retrospectively analyzed. Unique complications related to the Corsair microcatheter were also documented. Results Success recanalization of CTO were achieved in 73 (90.1%) patients. Crossing the CTO body with Corsair microcatheter was found in 56(84.8%) patients. The number of balloon utilized after Corsair microcatheter crossing the CTO was much lower than that of patients who Corsair microcatheter failed to cross (1.3±0.6 per patient versus 2.8±1.2per patient, P < 0.05). The success recanalization rate of combined using Fielder XT guidewire with Corsair microcatheter was 51.5%. There was no complications related to Corsair microcatheter during the index procedure, no major adverse cardiac events during in-hospital clinical follow-up. Conclusions Corsair microcatheter was safe and effective in the recanalization for CTO with transradialantegrade approach. It can simplify the CTO-PCI procedure and reduce the number of balloon catheters.
