RECOVER-HF - RandomizEd, Multi-Center, Double-Blinded Study of SynchrOnized Diaphragmatic Stimulation (SDS) for ImproVEment of Symptomatic Reduced Ejection Fraction Heart Failure

Symptomatic Diaphragmatic Stimulation (SDS) is a novel extra-cardiac device for patients who have symptomatic heart failure. Elevated intracardiac pressures are the hallmark of heart failure (HF) and a key pathological driver of disease progression and limited exertional capacity. The degree of cardiac pressure elevation is determined by preload, afterload, and pericardial restraint. The pericardium restrains the heart, and the degree of restraint is determined by the pericardial structure itself and the intrathoracic pressure. This aspect of HF pathophysiology is among the fundamental drivers…
