Overview

Retrospective cohort study finds echocardiographic parameters predict ventricular arrhythmias in AICD patients, indicating risk stratification may improve.

Key Points

  • This research aims to evaluate echocardiographic parameters for predicting ventricular arrhythmia risk post-AICD implantation.
  • Retrospective cohort study of AICD patients at Westmead Hospital (January 2014–May 2024)
  • Analyzed pre-implant transthoracic echocardiograms for structural and functional parameters
  • Identified ventricular arrhythmia events from medical records and device checks
  • Performed univariate and multivariate Cox regression analyses over 242 patients.
  • Among 242 patients, 98 had ventricular arrhythmias events.
  • Increased left-ventricular end-diastolic diameter, indexed LV mass, and right-ventricular diameter were associated with arrhythmias (p < 0.05).
  • LVEF and GLS were not associated with arrhythmias.
  • DCD was an independent predictor of VA events (HR 1.003; p = 0.022).
