June 23, 2022 updated by: Abbott Medical Devices

Study of Reduced Anti-coagulation/Anti-platelet Therapy in Patients With the HeartMate II LVAS (TRACE)

The purpose of this observational study is to obtain multi-center data on HeartMate II (HMII) patients managed with reduced anticoagulation or anti-platelet regimes, and the incidence of thrombotic and bleeding adverse events associated with these regimes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with HeartMate II VAD that are on reduced anticoagulation/antiplatelet regimine

Description

Inclusion Criteria:

  • HeartMate II Left Ventricular Assist Device (LVAD) patient
  • Patient has signed an informed consent for data collection.
  • Patient was discharged, or is being discharged, from the hospital after their initial LVAD implant surgery.

  • Patient:

    • at time of enrolling in study, is currently on, with the intention of being maintained on reduced anti-thrombotic therapy (RT) for chronic long-term management.

OR

-- On or after January 1, 2011 patient was being maintained on, or had been initiated with the intention of being maintained on, reduced anti-thrombotic therapy (RT) for chronic long-term management; but where RT was subsequently discontinued due to an adverse event or transplant, explant, or death.

Exclusion Criteria:

  • Patients under acute management of anti-thrombotic agents before a final decision on long term antithrombotic strategy.
  • Patients requiring a legal representative to sign consent form, rather than themselves.
  • Patient is being managed on other anti-thrombotic agents

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 1, 2011

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
