Destination Therapy Post Approval Study

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patient or legally authorized representative provides written authorization and/or consent per institution and geographical requirements
  • Patient is intended to receive or be treated with a HeartWare HVAD System for use as destination therapy
  • Patient is consented prior to the HVAD implant procedure

Exclusion criteria

  • Patient who is, or is expected to be inaccessible for follow-up
  • Patient with exclusion criteria required by local law
  • Patient is currently enrolled in or plans to enroll in any concurrent drug and/or device study that may confound results (i.e., no required intervention that could affect interpretation of all-around product safety and or effectiveness)
  • Patient less than 18 years of age.
  • Patient with previous support by long-term mechanical circulatory support (MCS), not including temporary mechanical circulatory support.

Treatment and study plan

HeartWare Ventricular Assist Device

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 names: HVAD

Primary outcomes

  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 outcomes

  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.
