Abstract:
Objective To evaluate the feasibility and efficacy of Guidezilla TM guide extension catheter in retrograde technique for chronic total occlusion (CTO) recanalization. Methods We retrospectively collected 119 CTO cases from the 2nd Cardiology Department of Guangdong General Hospital who had received retrograde percutaneous coronary intervention( PCI). The Guidezilla TMguide extension catheters were applied in 39 cases from October 2015 to November 2016. 80 CTO cases without using the Guidezilla TMguide extension catheter during PCI admitted between January 2015 and October 2015 were collected as the control. Results The overal success rate of the 2 group was 84.0%. The group using the Guidezilla TMguide extension catheter had a higher success rate(100% vs.76.2%,P<0.05).The baseline clinical characteristics of the two groups showed no statistical diff erence. In terms of CTO crossing diffi culty by J-CTO score, patient in the Guidezilla TMguide extension catheter group had higher percentage of diffi cult lesions(35.9% vs.15.0%,P<0.001)and very difficult lesions(61.5% vs.32.5%,P<0.001).Patients in the Guidezilla TMguide extension catheter group had more longer lesions(89.7% vs.72.5%,P=0.035),blunt proximal occlusion(53.8% vs.32.5%,P=0.030)and tortuosity lesions(84.6% vs.63.8%,P=0.020). More cases in the control group needed a second operation(63.8% vs.25.6%,P<0.001)and more ostial/bifurcation lesions(62.5% vs.30.8%,P=0.002).All cases had no target vessel revascularization or in-hospital death. Conclusions Guidezilla TMguide extension catheter is convenient and safe for complicated CTO retrograde PCI.
