    Sudden cardiac death (SCD) has an estimated global incidence of 30 to 100 per 10,000 individuals annually.

  • 2

    Left ventricular ejection fraction (LVEF) ≤ 35% is a well-established risk factor for SCD, guiding ICD implantation recommendations.

  • 3

    Approximately one-third of SCD cases occur in patients with LVEF ≤ 35%, while nearly half occur in those with preserved LV function.

  • 4

    Right ventricular dysfunction is associated with adverse outcomes and may serve as an important predictor of SCD and ventricular arrhythmias.

  • 5

    The meta-analysis included 7 studies to evaluate the association between right ventricular dysfunction and the risk of SCD or ventricular arrhythmias.
