Summary

The study evaluates the Double Kissing Crush (DKC) technique for complex coronary bifurcation lesions, focusing on the role of bifurcation angle and rewiring strategy.
Computational simulations were performed across three bifurcation angles (45°, 70°, and 100°) and multiple rewiring configurations. Results show that wide angles (100°) lead to poorer outcomes, including higher stent malapposition and unfavorable hemodynamics. Intermediate (70°) and narrow (45°) angles yield better results, but the optimal rewiring strategy differs by anatomy. Overall, no single approach is universally optimal, highlighting the need for patient-specific procedural planning.
