Descrizione dettagliata
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 behind the SDS therapy concept. SDS induces a temporal modulation of intrathoracic pressure.. When synchronized with the cardiac cycle, SDS may improve cardiac filling, cardiovascular pressure conditions, and cardiac performance
RECOVER HF is a prospective, randomized, doubled-blinded study of Synchronized Diaphragmatic Stimulation (SDS) delivered in an imperceptible manner in subjects with heart failure defined as New York Heart Association (NYHA) functional class II/III, left-ventricular ejection fraction (LVEF) <=40%, and QRS duration <=130ms despite receiving the appropriate heart failure guideline directed medical therapy (GDMT). All subjects will receive an implanted VisONE System. Two-weeks post implant subjects will be randomized in a 1:1 ratio into a SDS therapy active or control (SDS therapy inactive) arm with both arms receiving GDMT. At 6 months the control arm will have SDS therapy activated with all patients receiving therapy and GDMT throughout the remainder of the study period. The study will be conducted at up to 30 investigational sites in the United States and several outside the U.S. These centers will enroll subjects with the goal of randomizing approximately 270 subjects who meet the entry criteria.
