May support CCM consideration in narrow-QRS HFrEF; leaves open confirmation in randomized trials.
Cardiac contractility modulation represents a promising device-based therapeutic option for patients with symptomatic HFrEF and narrow QRS complexes who are ineligible for cardiac resynchronization therapy.
Abi‐Samra et al. (2016) conducted a review in Heart failure with reduced ejection fraction. Cardiac contractility modulation vs. Optimal medical therapy was evaluated. Cardiac contractility modulation improves quality of life, exercise tolerance, and heart failure symptoms in patients with reduced ejection fraction and normal or slightly prolonged QRS duration.
