Brief Summary:
The aim of this post market study is to assess the impact of sleep-disordered breathing on the well-being of patients according to the treatment chosen, i.e. with or without implantation of the remedē® system to treat sleep-disordered breathing.

Condition or disease
Sleep Apnea Central Sleep Disordered Breathing

Detailed Description:

The sponsor of this study, LivaNova, has a partnership with Respicardia, Inc who has developed a battery-powered implantable device that treats central sleep apnea. The device is used with a lead that delivers the stimulation therapy which causes the patient to breathe with a regular rhythm and an optional lead that senses breathing. This combination is called the remedē® system.

The aim of this study is

  1. to collect data in order to get a better understanding of the characteristics and/or symptoms related to central sleep apnea
  2. to collect safety information of all patients diagnosed with central sleep apnea
  3. to obtain additional short and lang term information on the safety and performance of the remedē® system, including an evaluation if there's an impact on the quality of life of patients treated with the the remedē® system in daily practice.

The information obtained from this study may provide better insight on the symptoms related to central sleep apnea, risk factors related to central sleep apnea therapy and use of the remedē® system which may help to treat other patients with potential sleep disordered breathing more appropriately.

Approximately 300 patients (to be) implanted with the remedē® system will participate in this study at approximately 40 sites in Europe. For this purpose the investigators aim to screen approximately 1500 patients with sleep-disordered breathing. Also patients diagnosed with central sleep apnea, but not receiving the device will be followed through phone calls for 2 years.

CSA patients without remedē system
For all patients diagnosed with CSA who will not move forward with remedē® system therapy, the intention is to obtain information on their alternate therapy, if any, and safety information, including all cause mortality and all cause hospitalizations during phone calls at 6, 12 and 24 months after enrollment.
CSA patients with remedē system

For all patients diagnosed with CSA and referred for implant / or have already been implanted with remedē system, information from the implant procedure will be collected.

Patients will be asked to complete quality of life questionnaires at baseline and during follow-up visits.

Patients will be evaluated at the time of therapy activation which may be followed by one or more titration visits. Patient follow-ups will be programmed at 6 and 12 months, and yearly, up to 5 years post-implant, until the last patients reach their 2-year follow-up.

Echocardiogram for patients with reduced ejection fraction (≤ 45%) and follow-up respiratory polygraphy are considered standard of care, however, to ensure sufficient data, related to the study objectives, are being collected, baseline and 12-months echocardiogram for a subgroup of patients and respiratory polygraphy at 12-month follow-up for all patients must be done when participating in this study:

Primary Outcome Measures :
  1. Incidence of All Cause Mortality, SAEs, Stimulation Complaints, Device and/or Cardiovascular Related Events From Implant up to 5 Years. [ Time Frame: From implant up to 5 years (collected until 24 month FU) ]

    Collect short and long term clinical data on safety of the remede system implanted in daily practice.

    This outcome measure was intended to be collected up to 5 years, but at time of early study termination the data were only monitored until 24 months for 1 patient.

Secondary Outcome Measures :
  1. Change in Apnea-hypopnea Index as Assessed by Polygraphy Compared to Baseline [ Time Frame: 12 months post-implant ]
    Evaluate changes in sleep study results at 12 months compared to baseline

  2. Impact on Quality of Life Compared to Baseline [ Time Frame: Up to 5 years post-implant ]
    Evaluate impact on Quality of Life by using a general questionnaire, a sleep-specific questionnaire and a questionnaire specific for heart failure patients

  3. Change in Reverse Remodelling Response as Assessed by Echo Compared to Baseline [ Time Frame: 12 months post implant ]
    Evaluate reverse remodeling response in patients with reduced ejection fraction at baseline

  4. Incidence of All Cause Mortality and Hospitalizations up to 2 Years After Diagnosis of Central Sleep Apnea [ Time Frame: Up to 2 years (collected until 6M FU) ]
    Collect site reported safety data on all patients diagnosed with central sleep apnea and not treated with the remede system

Other Outcome Measures:
  1. Collect Clinical Characteristics and Symptoms of Patients With Central Sleep Apnea [ Time Frame: screening ]
    Characterstics and symptoms of patients screened for sleep disordered breathing were not collected and analyzed.
