Insights
Cardiac resynchronization therapy with defibrillators (CRT-D) improved heart failure symptoms in most patients. However, significant cardiac events like death and arrhythmias still occurred unpredictably in 38% of patients.

Abstract:
Implantable cardiac defibrillators and resynchronization devices (CRT-D) are frequently used for heart failure patients. This is a retrospective study which included 50 patients with a CRT-D. The objective was to evaluate the prevalence of cardiac events (death, hospitalization for acute heart failure, ventricular arrhythmias). During 30-month follow-up, 4 patients (8%) died, 10 patients were hospitalized for acute decompensated heart failure (20%) and 5 patients (10%) presented an appropriate choc for a ventricular arrhythmia. In total, 19 patients presented at least one cardiac event (38%). An improvement in dyspnea was reported in 84% of patients. An improvement of left ventricular ejection fraction (LVEF) was reported in 74% of patients and 12% of them have normalized LVEF. In this study, the majority of patients implanted with a CRT-D presented an improvement of their symptoms. However, residual cardiac events were reported and remain unpredictable.
