Tapered coronary artery lesions (TCALs) are
often seen clinically, optimal stenting of TCALs remains challengeable. This
study sought to compare clinical outcomes between the modified single stenting
(MSS) and conventional overlapped stenting (COS) in treatment of TCALs. 150
patients were treated with MSS (MSS group), another 150 patients were matched
with propensity score matching from 5055 patients treated with COS (COS group).
Quantitative coronary angiography was performed to measure minimal lumen diameter
(MLD), late lumen loss (LLL). The primary endpoint was immediate angiographic
success, one-year cumulative major cardiac adverse events (MACEs) composing
cardiac death, target vessel myocardial infarction (TVMI), target lesion/vessel
revascularization (TLR/TVR) or stent thrombosis (ST). Post-procedural in-stent
