The Utility of a Wireless Implantable Hemodynamic Monitoring System in Advanced Heart Failure Patients Needing Left Ventricular Mechanical Circulatory Support

Abstract

An increase in intracardiac filling pressures is one of the primary hallmarks of progressive heart failure (HF). Multiple clinical studies have demonstrated that lowering cardiac filling pressures will alter morbidity and mortality in HF patients. Noninvasive wireless hemodynamic monitoring of cardiac output and pulmonary artery pressures in the recently published CHAMPION Trail demonstrated that careful monitoring of Class III HF patients significantly decreased in pulmonary artery mean pressures and resulted in fewer hospitalizations and more days alive outside of the hospital. We reviewed the clinical course of the subset of patients who were enrolled in the CHAMPION Trial that had further progression of their HF and required a ventricular assist device (VAD) or heart transplant.
