Key result
The deep intubation technique using a 5 French catheter was successfully performed in four complex percutaneous coronary intervention scenarios without incurring complications.
Why the study?
When transradial artery diameter precludes using thick guiding catheters during complex PCI, special techniques like deep intubation may be useful to provide adequate support.
Is the deep intubation technique using a 5 French catheter safe and effective for complex percutaneous coronary interventions?

Is the deep intubation technique using a 5 French catheter safe and effective for complex percutaneous coronary interventions?
The deep intubation technique using a 5 Fr catheter can be a safe, effective, and low-cost strategy to increase backup support during complex PCI when performed carefully.
Supports specialized techniques for small radial arteries in complex PCI; leaves open prospective validation before wider adoption.
Background: A successful percutaneous coronary intervention (PCI) on complex coronary anatomy can be up to 90% of cases and depends on many factors such as successfully guiding catheter support, which entails a perfect entry in the ostium of the treated artery, the guidewires ability to cross the culprit lesion and the stent profile. In some transradial artery cases the vessels diameter does not allow the use of a thick guiding catheter (from 6 to 8 Fr), in these cases special techniques such as "deep intubation" may be useful, if performed correctly.

Allende et al. (2021) conducted a case report in Complex coronary artery disease requiring PCI (n=4). Deep intubation technique using a 5 French catheter was evaluated on Procedural success without complications. The deep intubation technique using a 5 French catheter was successfully performed in four complex percutaneous coronary intervention scenarios without incurring complications.
