Brief Summary:

Medtronic is sponsoring the HeartWare™ HVAD™ Destination Therapy (DT) Post Approval Study (PAS) to further confirm safety and effectiveness of the HeartWare Ventricular Assist Device System (HVAD System) when used as intended, in "real-world" clinical practice.

The Destination Therapy Post Approval Study (DT PAS) is conducted within Medtronic's Product Surveillance Platform.


Condition or disease Intervention/treatment
Chronic Heart Failure Device: HeartWare Ventricular Assist Device

Detailed Description:
The HeartWare Destination Therapy (DT) Post Approval Study (PAS) is a prospective, observational, multi-site study. Enrollment into the DT PAS will be comprised of newly enrolled, commercial use DT patients with the HeartWare Ventricular Assist Device System (HVAD System). Patients enrolled in DT PAS will be followed for 5 years post-implant or until study closure, patient death, patient exit from the PAS (i.e., withdrawal of consent), or patient has HVAD device removed without replacement (i.e., transplant, recovery) or device is exchanged for non-HVAD. The total estimated study duration is approximately 7 years.

Group/Cohort Intervention/treatment
Patients implanted with HVAD System
Patients intended to be implanted with a HVAD for use as destination therapy are eligible for enrollment into the DT PAS and must be consented for the study prior to the HVAD implant.
 Device: HeartWare Ventricular Assist Device
The HVAD is an implantable centrifugal rotary blood pump that is implanted in the pericardial space and is designed to provide up to 10 L/min of blood flow from the left ventricular to the aorta. The HVAD System is comprised of three major components: the HVAD (pump) with inflow and outflow conduits, a Controller (microprocessor unit that controls the operation of the HVAD), and power sources (AC and DC power adapters that provide power to the Controller and implanted HVAD).
Other Name: HVAD


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Long-term complication free survival [ Time Frame: Implant to 2 years ]
    Complications include death, disabling stroke, or device malfunction or failure requiring exchange, explantation or urgent transplantation.


Secondary Outcome Measures :
  1. Rate of stroke [ Time Frame: Implant to 2 years ]
    The rate of stroke on device will be analyzed using Kaplan-Meier methods.

  2. Rate of late stroke [ Time Frame: 2 years post-implant to 5 years ]
    The rate of late stroke on device will be analyzed using Kaplan-Meier methods for those surviving stroke-free for 24 months post-implant.

  3. Stroke severity [ Time Frame: Occurrence of stroke to 24 weeks post-stroke ]
    Modified Rankin Scale (mRS) scores will be collected at the time associated with stroke on device and at 12 and 24 weeks post-stroke. The distribution of mRS scores for all strokes occurring in the study will be presented, separating stroke occurring prior to 24 months post-implant and those occurring greater than 24 months post-implant.
