  Purpose
Most people with heart failure take a number of medications that work in different ways. Patients and their families need to keep track of prescribed medications and follow instructions on how much to take and when to take them. Currently, doctors are guided primarily by symptoms. The device being studied in this trial (called the HeartPOD™ System) monitors heart function from inside your body and alerts the patient and physician of necessary changes to your medication.

Condition Intervention Phase
Heart Failure Device: HeartPOD™ System Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Hemodynamically Guided Home Self-Therapy in Severe Heart Failure Patients: A Prospective, Multi-center, Non-randomized, Open Label Study.

Primary Outcome Measures:
  • Freedom from Major Adverse Cardiac and Neurological Events (MACNE) at 6 weeks. [ Time Frame: 12 months ]

Enrollment: 40
Study Start Date: March 2005
Study Completion Date: June 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: HeartPOD™ System
Implantation of HeartPOD™ System
Device: HeartPOD™ System
HeartPOD™ device automatically measures left heart pressures throughout the day.

Detailed Description:
The Sponsor believes that direct measurements from your heart may provide an accurate, reliable and medically acceptable way of telling you and your doctor that your CHF is worsening hours to days before the above symptoms would develop and you would notice. This may enable you and your doctor to take preventative measures and avoid hospitalization.

  • Female subjects of childbearing potential must have a negative pregnancy test within seven (7) days before the procedure.
  • Central venous vascular access.
  • Capable of Valsalva maneuver with airway pressure > 40 mm Hg for 10 seconds.
  • The subject and the treating physician agree that the subject will comply with all required post-procedure follow-up, and that the patient is capable of correct device use as outlined in the protocol.
  • Written informed consent.

Exclusion Criteria:

  • Resting systolic blood pressure < 90 or > 180 mmHg.
  • Acute MI, unstable ischemic syndrome within the last 6 weeks.
  • Percutaneous coronary intervention (PCI) or cardiac surgery performed or planned within 6 weeks.
  • Coexisting stenotic valve lesions, vegetations, hypertrophic cardiomyopathy, amyloidosis or other infiltrative heart disease, constrictive, restrictive disease, tamponade, or moderate or large pericardial effusion.
  • Subject has a history of deep venous thrombosis or pulmonary embolism.
  • Surgical correction of congenital heart disease involving atrial septum.
  • CVA or TIA within 6 months. History of uncorrected cerebral vascular disease.
  • Atrial or ventricular thrombus, tumor or systemic thromboembolism.
  • Chronic atrial fibrillation.
  • Symptomatic bradyarrhythmia or sustained VT/VF unless successfully treated with cardiac rhythm management device for 6 weeks.
  • Atrial septal defect or patent foramen ovale > 2 mm in diameter.
  • Life expectancy < 1 year from malignancy, primary pulmonary hypertension, renal, hepatic, or neurological condition, etc.
  • Gastrointestinal bleeding during the last 6 months.
  • Coagulopathy or uninterruptible anticoagulation therapy or unable to take antiplatelet medications.
  • Creatinine > 2.5 gm/dl
