Early clinical experience with Guidezilla for transradial interventions in China

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Medical Devices

Background:

• Transradial intervention (TRI) complexity is increased by anatomic variations, calcified, tortuous, and angulated lesions.
• The Guidezilla mother-and-child catheter offers enhanced support for complex interventions.
• Limited published data exists on the use of the Guidezilla in TRI, particularly in Chinese populations.

Purpose of the Study:

• To investigate the efficacy and safety of the Guidezilla guide extension catheter in complex coronary interventions.
• To evaluate the performance of Guidezilla in facilitating transradial interventions in Chinese patients.

Main Methods:

• Retrospective collection of clinical characteristics, angiographic details, and in-hospital outcomes for 32 Chinese patients undergoing TRI between June 2015 and August 2017.
• Analysis of patient demographics, lesion complexity (Type B/C, tortuous, angulated), target vessels (RCA, LAD), and procedural outcomes with Guidezilla use.

Main Results:

• The study included 32 patients (81% male, mean age 59.44 years) with complex coronary lesions (53% Type C, 41% tortuous, 22% angulated).
• Technique success was 100%, and procedural success was 94% using the Guidezilla catheter.
• Mean stent diameter was 2.97 mm, length 27.19 mm, with a mean Guidezilla intubation depth of 7.66 cm into the target vessel.

Conclusions:

• The Guidezilla catheter extension safely and successfully facilitated transradial interventions in complex coronary artery lesions.
• This device proves beneficial for interventionalists performing challenging procedures, enhancing support and success rates.
