Routine intracoronary imaging-guided left main coronary intervention.

ABSTRACT: Left main (LM) percutaneous coronary intervention (PCI) with routine intracoronary imaging guidance is recommended; however, its real-world effectiveness remains unclear. A total of 743 consecutive patients undergoing drug-eluting stent implantation for de novo unprotected LM lesions across 19 Japanese National Hospital Organization hospitals where routine imaging guidance was adopted were analyzed. The primary endpoint was 1-year major adverse cardiovascular and cerebrovascular events (MACCE), comprising all-cause death, cerebrovascular disorder, clinical-driven revascularization, and myocardial infarction. In this cohort, acute coronary syndrome was present in 31.2%, with 39.3% classified as Canadian Cardiovascular Society functional angina (CCS) class ≥ III. LM bifurcation lesions were
