Assessment of Left Ventricular Function After Percutaneous Coronary Intervention for Chronic Total Occlusion.

ABSTRACT:

Background

The impact of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) on left ventricular ejection fraction (LVEF) remains controversial.

Methods

We included patients who underwent CTO PCI (2018-2022) with reported baseline and follow-up LVEF (window 1-18 months). Stratified analyses according to procedural success, baseline LVEF, and target vessel were performed. Logistic regression analysis was performed to assess predictors of LVEF improvement.

Results

We included 142 patients with available LVEF data, of whom 121 had successful CTO PCI (85.2%). Overall, mean age was 65.4 ± 10.3 years, 76.1% were men, and 81.0% were White. The attempted CTO vessel was left anterior descending in 31.7%, left circumflex in 17.6%, and right coronary arter
