Proximal buddy in jail technique: A bail out technique to increase guide support

Area of Science:

• Interventional Cardiology
• Medical Devices
• Vascular Interventions

Background:

• Percutaneous coronary intervention (PCI) often requires specialized techniques for complex lesions.
• "Buddy-in-jail" technique is used to aid stent delivery in challenging coronary artery cases.
• Limited data exists on the safety and efficacy of this technique with various jailed wires and lesion types.

Purpose of the Study:

• To evaluate the effectiveness of the "buddy-in-jail" technique in tortuous and rigid coronary arteries.
• To compare the outcomes using common vs. neighboring arteries as "buddy" vessels.
• To assess the performance of hydrophilic-coated versus non-hydrophilic-coated jailed wires.

Main Methods:

• Retrospective study of 15 patients undergoing PCI from June 2014 to December 2016.
• Application of the "buddy-in-jail" technique after failed initial stent or balloon delivery.
• Comparison of success rates based on "buddy" vessel location and jailed wire type.

Main Results:

• Successful stent delivery in 13 out of 15 patients (86.7%) using the "buddy-in-jail" technique.
• Similar success rates observed when using common (87.5%) versus neighboring (85.7%) arteries as "buddy" vessels (p > 0.05).
• High success rate with hydrophilic-coated jailed wires (100%) compared to non-hydrophilic-coated (77.8%), though not statistically significant (p > 0.05). All wires were safely extracted.

Conclusions:

• The "buddy-in-jail" technique is a viable alternative for distal stent delivery in complex coronary lesions.
• It can be safely and effectively employed in both common and neighboring coronary arteries.
• Both hydrophilic and non-hydrophilic-coated wires can be utilized as jailed wires in this technique.
