Current Evidence and Future Perspective for Coronary Bifurcation Stenting.

Coronary bifurcation lesions account for 15%-20% of all percutaneous coronary interven tions and are associated with greater procedural complexity and consequently at higher risk for cardiac adverse events. Early clinical trials in the interventional approach to bifurcation lesions supported provisional stenting. However, the most recent randomized studies have indicated potentially superior results using a double-kissing crush technique, particularly for unprotected distal left main bifurcation lesions. Moreover, many operators recently favor double-kissing mini-culotte, nanocrush, and double-kissing nanocrush stenting techniques for bifurcation lesions. In this review, we describe the traditional and novel bifurcation stenting techniques and the current evidence for each and review general principles for bifurcation percutaneous coronary intervention.
