About this study

The MCS Korea PMS is an observational study conducted at two sites. This MCS Korea PMS is required by the Ministry of Food and Drug Safety (MFDS) as a condition of product approval according to Regulation on Medical Device Re-examination. The designated re-examination period is seven years after the approval date (06 Dec 2013 ~ 05 Dec 2020). All patients who require treatment of a commercially available HVAD System for approved indications between the designated re-examination period at a participating PSR site are eligible for enrollment. All enrolled patients will be followed until patient death, transplant, explant (where applicable), or the end of the study, on 05 Dec 2020.

Who can participate

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 has or is intended to receive or be treated with an eligible product
  • Patient is consented within the enrollment window or waiver of consent is approved

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)

Treatment and study plan

HeartWare Ventricular Assist Device

Device

The Medtronic HVAD® System is comprised of three major components: the HVAD Pump with inflow and outflow conduits, a Controller and power sources. In addition to these components, the system includes a Monitor, Battery Charger, AC and DC power adapters, and a Carrying Case. The HVAD® System is indicated for hemodynamic support in patients with advanced, refractory left ventricular heart failure; either as a bridge to cardiac transplantation (BTT), myocardial recovery, or as destination therapy (DT) in patients for whom subsequent transplantation is not planned.

Other names: HVAD

Primary outcomes

  1. Survival rate up to 6 months and 24 months post-implant

    Time frame: Implant to 6 months, 24 months

    Success (or survival) will be defined as survival, heart transplantation, or explantation for recovery at 6 months post-implant for BTT patients, survival at 24 months post-implant for DT patients.

Secondary outcomes

  1. Quality of life, as measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ), up to 24 months post-implant

    Time frame: Implant up through 24 months

    Characterize changes in quality of life over time

  2. Functional status, as measured by the New York Heart Association (NYHA) classification, up to 24 months post-implant

    Time frame: Implant up through 24 months

    Characterize changes in NYHA class over time

  3. Functional status, as measured by the 6-minute walk test, up to 24 months post-implant

    Time frame: Implant up through 24 months

    Characterize changes in 6-min walk test results (walked distance in meters) over time

Other outcomes

  1. INTERMACS-defined Adverse Events up to 24 months post-implant

    Time frame: Implant to 24 months

    Summarize adverse events
