Deep Dive Rendezvous as a Novel Alternative Technique for Conventional Externalization in Retrograde Chronic Total...

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Interventions

Background:

• The retrograde approach is crucial for Chronic Total Occlusion Percutaneous Coronary Intervention (CTO-PCI) when antegrade techniques fail.
• Conventional externalization methods in retrograde CTO-PCI present challenges like complexity, high equipment needs, and collateral vessel rupture risk.

Purpose of the Study:

• To introduce and detail the Deep Dive Rendezvous (DDR) technique as a novel solution for retrograde CTO-PCI externalization.
• To present DDR as an improvement over conventional externalization, aiming to simplify procedures and enhance safety.

Main Methods:

• The study details the Deep Dive Rendezvous (DDR) technique, an advancement of existing rendezvous approaches.
• DDR involves deep intubation into the retrograde system for enhanced guidewire support during CTO-PCI.

Main Results:

• The DDR technique provides enhanced guidewire support within the retrograde system.
• It aims to streamline the externalization process, potentially reducing procedural complexity and equipment requirements.
• The technique is designed to minimize risks associated with collateral vessel rupture.

Conclusions:

• Deep Dive Rendezvous (DDR) offers a streamlined and effective alternative to conventional externalization in retrograde CTO-PCI.
• This technique can reduce procedural complications and preserve collateral vessel integrity.
• DDR is versatile, serving as both a primary strategy and a bailout option for challenging CTO-PCI cases.
