Overview

Retrospective cohort study shows echocardiographic parameters predict ventricular arrhythmia risk in AICD patients, indicating need for better risk stratification.

Key Points

  • The study aims to evaluate echocardiographic and strain parameters as predictors of ventricular arrhythmia risk post-AICD implantation.
  • Conducted a retrospective cohort study at Westmead Hospital, Australia.
  • Evaluated pre-implant transthoracic echocardiograms for various structural and functional parameters.
  • Analyzed VA events from electronic medical records and device checks using multivariate Cox regression.
  • 98 out of 242 patients experienced ventricular arrhythmia events.
  • Increased left-ventricular end-diastolic diameter and indexed LV mass correlated with VA events.
  • Delta contraction duration was identified as an independent predictor of VA events.
