"Stick and Swap" Technique Through the ReCross Dual-Lumen Microcatheter

Area of Science:

• Interventional Cardiology
• Cardiovascular Disease Management

Background:

• Antegrade dissection and re-entry (ADR) for coronary chronic total occlusions (CTOs) is limited by extraplaque hematoma formation.
• The ReCross dual-lumen microcatheter has shown potential in facilitating re-entry in complex CTO cases.

Observation:

• A patient presented with angina and cardiac arrest due to a right coronary artery CTO.
• The ReCross microcatheter was utilized, with wires advanced through its dual lumens.
• Successful re-entry into the distal true lumen was achieved.

Findings:

• Utilizing the ReCross microcatheter for CTO wiring resulted in a smaller extraplaque hematoma.
• This approach facilitated the ADR procedure, enhancing ease of crossing.
• The ReCross catheter demonstrated advantages in terms of lower cost and broader availability.

Implications:

• This case underscores the value of the ReCross catheter in managing complex coronary artery disease.
• Multimodality intervention strategies incorporating this device can improve patient outcomes.
• The ReCross microcatheter represents an accessible and cost-effective tool for interventional cardiologists.
