Feasibility and clinical outcomes of rotational atherectomy for heavily‐calcified side branches of complex coronary bifurcation lesions in the real‐world practice of the drug‐eluting stent era

Abstract

RA for SB preservation in complex and heavily-calcified bifurcation lesions was feasible with high success rate and quite favorable long-term outcomes in the drug-eluting stent (DES) era. Given the higher rates in SB perforation and acute CIN, we recommend that SB RA should be conducted by experienced operators.
