Preliminary application experience of GuidezillaTM guide extension catheter during complex coronary percutaneous coronary intervention procedure / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate the clinical safety and efficacy of GuidezillaTM guide extension catheter during complex coronary percutaneous coronary intervention(PCI). Methods A total of 13 patients were included in the studywho presented with complex coronary lesions during PCI. Stents or balloons could not be delivered to these complex lesions with conventional approach and GuidezillaTM guide extension catheters were used. Results Among these 13 patients,there were 7 CTO lesions,7 calcified lesions, 6 tortuous lesions,8 diffuse lesions,8 distal lesions and 8 lesions with pre-existing stents. PCI success rate was 100% .In one patient,GuidezillaTM guide extension catheter was obstructed which were relieved after stent implantation. There was no major adverse cardiac event(MACE) during follow-up.Conclusions The GuidezillaTM guide extension catheter was safe and effective for PCI of complex coronary artery lesions.
