Echocardiographic Predictors of Ventricular Arrhythmias Post-Automatic Implantable Cardioverter-Defibrillator Implantation.

ABSTRACT: (1) Background: Ventricular arrhythmias (VAs) are a leading cause of morbidity and mortality in ischemic and non-ischemic heart disease. While automated implantable cardioverter-defibrillators (AICDs) are standard treatment for high-risk patients, predicting future VA post-implantation remains limited. This study evaluated echocardiographic and strain parameters for predicting VA risk in AICD recipients. (2) Methods: This retrospective cohort study included patients who underwent AICD implantation at Westmead Hospital, New South Wales, Australia (January 2014-May 2024). Pre-implant transthoracic echocardiograms (TTEs) were analysed for structural and functional parameters, including left-ventricular (LV) ejection fraction (LVEF), LV global longitudinal strain (GLS), mechanical dispersion (
