Official title

Assessment of the Safety and Efficacy of a Combined Cardiac Contractility Modulation and Implantable Cardioverter Defibrillator Device for Subjects With Heart Failure and Reduced Ejection Fraction

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this clinical trial is to demonstrate that the OPTIMIZER® Integra CCM-D System (the "CCM-D System") can safely and effective convert induced ventricular fibrillation (VF) and spontaneous ventricular tachycardia and/or ventricular fibrillation (VT/VF) episodes in subjects with Stage C or D heart failure who remain symptomatic despite being on guideline-directed medical therapy (GDMT), are not indicated for cardiac resynchronization therapy (CRT), and have heart failure with reduced left ventricular ejection fraction (LVEF ≤40%). Eligible subjects will be implanted with the CCM-D System. A subset of subjects will be induced into ventricular fibrillation "on the table" in the implant procedure room. During the follow-up period, inappropriate shock rate and device-related complications will be evaluated. The follow-up period is expected to last at least two years.
