Comparative Study
Emergent versus elective percutaneous stent implantation in the unprotected left main: long-term outcomes from a single-center registry.
Unprotected left main (ULM) coronary disease is considered by contemporary guidelines a class I indication for surgery. However, percutaneous coronary intervention (PCI) is often carried out in the ULM in either emergent or high-risk elective procedures. The aim of this study was to evaluate ULM-PCI as a feasible and safe procedure in the emergent setting, and to analyze outcomes in both scenarios. ⋯ Emergent PCI of the ULM exhibits worse in-hospital outcomes as compared to elective procedures. However, after discharge, long-term outcomes remain comparably good between groups.
