Four patients received a drug-coated balloon.
The mean operation time was 58 min, and the overall success rate was 94.1%. The most common indication for GGEC I use was heavy calcification (67%), followed by extreme tortuosity (12.2%), extreme tortuosity and heavy calcification (10.9%), distally located lesion (4.5%), picking up the retrograde wire (3.2%), anomalous vessel origin (1.8%), and releasing the burr incarceration (0.4%). A total of 237 target lesions were treated, most being type C lesions (95.8%). Coronary angiography results indicated that most patients (77.8%) had triple-vessel lesions, including 47.5% with chronic total occlusion (CTO).
#Guideliner balloon anchor technique series
This case series study included patients with CAD who underwent TRI using the GGEC I between August 2016 and January 2019 at the First Affiliated Hospital of Xi’an Jiaotong University.Ī total of 221 patients aged 65.1 ± 9.26 years were included. This study aimed to evaluate the effectiveness and complications of the Guidezilla™ guide extension catheter I (GGEC I) in transradial coronary intervention (TRI). Percutaneous coronary intervention (PCI) is the preferred treatment method for coronary artery diseases (CAD). Further clinical evaluation will be required to assess the role of this new device in PCI.
The CrossLiner is a next generation guide extension system that may offer advantages over first generation devices. The average depth of guide extension delivery/ “intubation” was 12.9☓.6 cm for the CrossLiner and 5.6☑.1 cm for the first-generation guide extension (p < 0.001). The CrossLiner crossed distally and through a distal stented segment in 8/8 vessels, while the first-generation devices were stuck proximal to the stent (n=2/8) or at the stent edge (n=4/8), or passed partially into the deployed stent with difficulty (2/8) vessels (p < 0.0002 for deliverability). Data were collected from 8 coronary vessels from four animals, to evaluate the ability to deeply intubate the vessel with the guide extension. The CrossLiner was tested in a head-to-head study with the GuideLiner™ and GuideZilla™ in a porcine coronary model, with stenting. The CrossLiner™ is a next generation guide extension “system” intended to allow safe, deep, coronary intubation. First generation guide catheter extension devices are monorail, blunt ended tubular structures with limitations. Guide catheter extension is an integral part of percutaneous coronary intervention (PCI).
