Summary

The study objectives are to demonstrate the ease and safety of bilateral cervically implanted phrenic nerve stimulators for Central Sleep Apnea in patients with Heart Failure. To demonstrate the efficacy, both in the short and long term, of implanted phrenic nerve stimulators in patients with Central Sleep Apnea and Heart Failure. Central Sleep Apnea is a form of hypoventilation syndrome, for which this device is FDA approved. We will also determine if the patient's quality and duration of life is improved by using the PNS to treat CSA in heart failure patients.

Detailed description

This is a multi-center prospective cohort study to monitor the effect of bilateral phrenic nerve stimulation for treatment of central sleep apnea (CSA) in patients with heart failure. There will be 2 groups of study patients, both with CSA and heart failure. One group will receive the phrenic nerve pacer, and one will not. Both groups will have the same medical oversight, management, and assessment of heart health whether they receive the pacer or not. Subjects will have a physical exam, review of medications, New York Heart Association (NYHA) functional classification assessment for heart failure, Minnesota Living With Heart Failure (MLWHF) Questionnaire for quality of live assessment and blood test for Pro-BNP. In-lab sleep study will be required if subject haven't had one within 3 months, and Echocardiogram, if subjects haven't had one within 30 days. If subjects are willing to have stimulator placement procedure, they'll have an ENT consult. Subjects in the procedure arm will have Phrenic Nerve Stimulator placement procedure, and 3 weeks after procedure follow up visit with ENT doctor to activate the device and have sleep study to confirm proper settings.
