Abstract

Coronary chronic total occlusion (CTO) is interruption of antegrade coronary flow with TIMI grade 0 flow for equal or more than three months with incidence up to 16-18% among patients with coronary artery disease. Revascularization procedures aim to improve the patient's quality of life, exercise capacity and left ventricular function. Assessing the longitudinal myocardial deformation using 2D speckle tracking echocardiography is beneficial method to predict the subclinical recovery of hibernating viable myocardium after CTO percutaneous coronary intervention (CTO-PCI).
AIM OF THE WORK:
The aim of present study was to evaluate the value of 2D-STE in assessment of left ventricular reverse remodeling in patients with CTO who underwent revascularization through percutaneous coronary intervention (PCI). The assessment was conducted immediately after the procedure and three months later.
SUBJECTS AND METHODS:
This study included 54 patients who presented to Alexandria Main University Hospitals with chronic coronary total occlusion treated by PCI and evaluate LV reverse remodeling immediately after and 3 months after revascularization using 2D speckle tracking echocardiography.
