Aims: We sought to capture the daily practice of bifurcation stenting by means of a worldwide registry and to investigate how post-implantation deployment techniques influence clinical outcomes. Methods: Data from the e-ULTIMASTER registry were used to perform an analysis of 4,395 patients undergoing percutaneous coronary intervention for bifurcation lesions. Inverse probability of treatment weights (IPTW) propensity score methodology was used to adjust for any baseline differences. The pri-mary outcome of interest was target lesion failure (TLF) at one year (follow-up rate 96.2%). Results: The global one-year TLF rate was low (5.1%). The proximal optimisation technique (POT) was used in 33.9% of cases and was associated with a reduction in the adjusted TLF rate (4.0% [95% confidence interval: 3.0-5.1%] vs 6.0% [5.1-6.9%], p PB Europa edition SN 1774-024X YR 2021 FD 2021-12-01 LK https://hdl.handle.net/10668/25646 UL https://hdl.handle.net/10668/25646 LA en DS RISalud RD Apr 14, 2025
