Study Description
Brief Summary:

This is a limited safety and feasibility study to evaluate the PVSS Introducer and Paracor Ventricular Support System when used to treat patients with heart failure. The implant, which is loaded onto the delivery system, is placed over the epicardial surface of the right and left ventricles.

No formal hypothesis testing will be performed; descriptive statistics will be used to summarize patient outcomes. The results of the study will be used to guide the design and sample size estimation of future studies.

Arms and Interventions

Intervention Details:
    Device: Placement of the PVSS Implant
    Implant is placed on epicardial surface of the heart surrounding both the right and left ventricles, to provide mechanical support to the ventricular walls.
    Other Names:
    • HeartNet
    • Ventricular support device
    • Ventricular elastic support therapy

Outcome Measures

Primary Outcome Measures :
  1. Death or Additional Surgical Session at 6 Months [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Implant Success (Number of Participants Successfully Implanted) [ Time Frame: 1 day ]
    "Implant success" refers to the ability to successfully deliver a device onto the epicardial surface and leave the device in a satisfactory position.

  2. Change in NYHA Functional Class [ Time Frame: Baseline to 6 months ]
    Change in NYHA functional class between baseline and 6 months. "Maintained" means the participant's functional class remains the same as baseline. "Improved" means the participant's functional class has improved (become lower in number) by at least one class. "Worsened" means the participatn's functional class has deteriorated (become higher in number) by at least one class.

  3. Changes in Left Ventricular Diameters [ Time Frame: Baseline to 6 months ]
    Mean change in left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) from baseline to 6 months (echocardiographic measurements)

  4. Changes in Left Ventricular Volumes [ Time Frame: Baseline to 6 months ]
    Mean change in left ventricular end-diastolic volume (LVEDv) and left ventricular end-systolic volume (LVESV) from baseline to 6 months (echocardiographic measurements)

  5. Change in Left Ventricular Ejection Fraction [ Time Frame: Baseline to 6 months ]
    Mean change in left ventricular ejection fraction from baseline to 6 months (echocardiographic measurements)

  6. Change in Left Ventricular Mass [ Time Frame: Baseline to 6 months ]
    Mean change in left ventricular mass from baseline to 6 months (echocardiogram measurements)

  7. Changes in 6 Minute Walk [ Time Frame: Baseline to 6 months ]
    Mean change in 6 minute walk distance (meters) between baseline and 6 months

  8. Changes in Cardiopulmonary Tests [ Time Frame: Baseline to 6 months ]
    Mean change in Peak VO2 (ml/kg/min) between baseline and 6 months

  9. Mean Changes in Overall Minnesota Living With Heart Failure (MLHF) Quality of Life Questionnaire Score [ Time Frame: Baseline to 6 months ]
    The MLHF Quality of Life (QOL) Questionnaire evaluates the effects of heart failure on a subject's physical, emotional, social and mental dimensions of quality of life. Each of 21 questions is scored as to how much heart failure has impacted the subject, from 0-no impact to 5-very much (overall score can range from 0 to 105). Prior studies have shown a 10-point improvement (10-point decrease in overall score) correlated with a 1 NYHA class improvement, and 10-point worsening (10-point increase in score) was associated with a higher risk of hospitalization or death.

  10. Number of Adverse Events [ Time Frame: Study duration ]
    Total adverse events reported prior to study closure

  11. Number of Participants Who Died [ Time Frame: Study duration ]
    Total number of patient deaths reported prior to study closure
