Complex coronary bifurcation revascularization by means of very minimal crushing and ultrathin biodegradable polymer DES: Feasibility and 1-year outcomes of the "Nano-crush" technique.

Aim: To assess feasibility and 1-year outcomes of ultrathin biodegradable polymer double stenting using a very minimal crushing (nano-crush technique) in a series of patients with large (≥2.5mm) complex coronary bifurcation.

Methods: From January 2015 to June 2016, patients referred for large (≥2.
