The GL catheter is an adjunctive interventional device which enhances and amplifies CTO-PCI. The overall success rate was 88.9 ± 0.32% there were no relevant complications. All procedures were performed femorally the retrograde approach was used in 27.8 ± 0.46% of cases. The Japanese CTO score reflecting lesion complexity was 3.56 ± 0.78.

The GL is a coaxial, monorail guiding catheter extension delivered through a standard guiding catheter and is available in different sizes.Īlmost all lesions were classified as severely calcified (94.4 ± 0.24%). We examined 18 patients and used the GL catheter to overcome poor support and excessive friction in standardized antegrade and retrograde CTO procedures. The purpose of this study was to assess the feasibility of the GuideLiner (GL) catheter use. Failure of delivering a stent or a balloon across the target lesion during percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), especially in arteries with calcified tortuous anatomy, is often due to insufficient backup support from the guiding catheter.
