Area of Science:

  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) presents unique challenges.
  • The retrograde approach is vital for successful CTO recanalization.

Purpose of the Study:

  • To highlight the importance of the retrograde technique in CTO PCI.
  • To describe the reverse controlled antegrade and retrograde subintimal tracking (CRT) technique.

Main Methods:

  • The CRT technique involves a stepwise approach for CTO recanalization.
  • This method is utilized as a primary strategy or after failed antegrade dissection reentry.

Main Results:

  • The CRT technique is the most common retrograde approach for CTO recanalization.
  • A structured, stepwise application of this technique is essential for procedural success.

Conclusions:

  • The retrograde approach, specifically CRT, is a cornerstone of successful CTO PCI.
  • Mastering a stepwise methodology for CRT is key to achieving optimal patient outcomes.
