Impact of ultra-long second-generation drug-eluting stent implantation

Objectives This study investigated the safety and prognosis of ultra-long second DES (UL-2nd DES) implantation in real-world practice. Background Long stenting is a widely known predictor of stent thrombosis (ST) or target lesion revascularization (TLR) in first-generation drug-eluting stents (DES). Methods Participants were 1,669 patients (2,763 lesions) who had undergone successful second DES implantation; they were assigned to one of three groups: ultra-long 2nd DES (UL-DES; >50 mm, 166 patients, 259 lesions), long second DES (L-DES; 20–50 mm, 758 patients, 1,212 lesions), or short second DES (S-DES
