Marked Long-Term PVC Reduction During PCI for LCx CTO From the LV Summit Origin

Key Result

PVCs originating from the LV summit were markedly reduced long-term during PCI for left circumflex artery CTO near the left main trunk.

Key Points

The study aims to investigate the effect of PCI on arrhythmias originating from the LV summit during procedures for the left circumflex artery.
Evaluated arrhythmias during PCI procedures
Focused on the left circumflex artery
Monitored patients near the left main trunk (LMT)
Observed significant reduction in premature ventricular contractions (PVC)
Noted lasting effects on arrhythmias post-PCI

Structured PICO

Does PCI for LCx CTO reduce PVCs originating from the LV summit?

Population

Patients with premature ventricular complexes (PVCs) originating from the LV summit and left circumflex artery (LCx) chronic total occlusion (CTO)

Intervention

Percutaneous coronary intervention (PCI) for the left circumflex artery near the left main trunk (LMT)

Outcome

Long-term PVC reduction/suppressionsurrogate

PCI for LCx CTO may result in marked long-term reduction of PVCs originating from the LV summit.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Arrhythmias originating from the LV summit may be suppressed during PCI for the left circumflex artery near the LMT.
