The impact of the bifurcation angle for the Nano-Crush two-stent coronary bifurcation technique on long-term outcomes in a real-world clinical population.

Aim: This study aims to assess the direct impact of bifurcation angle (BA) on immediate procedural outcomes and patient prognosis post-Nano-Crush stenting for coronary bifurcation lesions.

Methods: A retrospective analysis was conducted for all consecutive patients treated with the Nano-Crush technique across two high-volume interventional centers from January 2020 to October 2022.

Primary Endpoint: comparison of target lesion failure rate in two cohorts based on bifurcation angle (<70° vs.
