Area of Science:

  • Interventional Cardiology
  • Cardiovascular Surgery

Background:

  • Complex coronary bifurcation lesions pose significant challenges in percutaneous coronary intervention.
  • Existing stenting techniques may yield suboptimal results for these complex anatomies.

Purpose of the Study:

  • To highlight the advantages of the double kissing (DK) crush technique for complex coronary bifurcation lesions.
  • To outline the critical technical steps required for successful DK crush stenting.

Main Methods:

  • The DK crush technique involves sequential stenting of the side branch (SB) and main vessel (MV), with specific kissing balloon inflations.
  • Key procedural elements include precise wire re-entry into the SB stent's true lumen, balloon anchoring, high-pressure non-compliant balloon inflations, and proximal optimization technique (POT).

Main Results:

  • The DK crush technique has demonstrated clinical advantages over other stenting methods for complex bifurcation lesions.
  • Meticulous attention to procedural details, such as wire position and inflation techniques, is essential for achieving optimal angiographic results.

Conclusions:

  • The DK crush technique is a valuable approach for complex coronary bifurcation lesions.
  • Lesion stratification prior to intervention and adherence to specific technical maneuvers are recommended for improved outcomes.
