Trends in Unprotected Left Main Percutaneous Coronary Intervention and Clinical Outcomes
In a nationwide Japanese PCI registry, unprotected LM PCI consistently accounted for 5% of PCI procedures. Although unadjusted in-hospital mortality rose modestly over time, the findings indicate this was largely explained by increasing patient complexity, with risk-adjusted outcomes remaining stable, supporting the continued role of LM PCI as a safe revascularization option in contemporary practice.
