HVAD(TM) SMART 1.0 Study

July 30, 2021 updated by: Medtronic Cardiac Rhythm and Heart Failure

HVAD(TM) SMART 1.0 Study: A Prospective Study of the HVAD(TM) SysteM WAvefoRm and Logfile CharacTeristics

The purpose of HVAD Smart 1.0 study is to collect HVAD device data (i.e., waveform + logfile + pump parameter) in various clinical conditions (e.g., routine follow-up visits, experiencing adverse events) to support development of predictive and actionable algorithms. The collected data will be used to characterize HVAD flow waveform and logfile pattern changes that precede a qualifying adverse event, as well as characterize "normal" HVAD flow waveform and logfile patterns (subjects free from any qualifying adverse event, any hospital readmissions related to a SAE, or any parenteral medical therapy for heart failure management (e.g., inotropes, diuretics, etc.) or ultrafiltration in last 30 days). In addition, the study will collect data to evaluate the utility of CareLink in HVAD patients. The study will not involve any investigational testing and the market-released devices will used as per the approved labelling.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adult, advanced heart failure patients that meet patient selection criteria for left ventricular assist device (LVAD) implant for any approved indication and implant strategy will be considered for the study.

Description

Inclusion Criteria:

  • Greater than or equal to 18 years of age:
  • Refractory, advanced heart failure patient that is either: Prospectively identified as a candidate to receive the commercial HVAD system as their first durable left Ventricular Assist Device (LVAD) implant for approved indications; or within 10 days of receiving the commercial HVAD system as their first durable LVAD for approved indications
  • Patient provides written authorization and/or consent per institution and geographical requirements

Exclusion Criteria:

  • patient who is, or is expected to be inaccessible for follow up
  • patient with previous durable mechanical circulatory support device
  • patient with planned Bi-VAD procedure
  • patient with exclusion criteria required by local law
  • patient is currently enrolled in or plans to enroll in an 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). Concomitant observational studies allowed if permitted by IRB/EC

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Heart Failure Event Characterization
Time Frame: data collected as events occur throughout study follow-up period; up to the 12 month follow-up visit
HVAD flow waveform and logfile pattern changes
data collected as events occur throughout study follow-up period; up to the 12 month follow-up visit

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Qualifying Adverse Event Characterization
Time Frame: data collected as events occur throughout study follow-up period; up to the 12 month follow-up visit
Measuring HVAD flow waveform and logfile pattern changes for ICVA, HCVA, Pump Thrombosis (PT), GI Bleed, Sepsis, Supraventricular Arrhythmia, Ventricular Arrhythmia, or RHF.
data collected as events occur throughout study follow-up period; up to the 12 month follow-up visit
Non-AE/SAE Characterization Group
Time Frame: data collected throughout study follow-up period; up to the 12 month follow-up visit
Measuring waveform and logfile for subjects in the previous 30 days free from: qualifying AE, hospital readmissions due to SAE, parenteral med therapy for HF management or ultrafiltration.
data collected throughout study follow-up period; up to the 12 month follow-up visit
CareLink Utilization
Time Frame: Up to 12 months post-implant
Characterizing the utility of CareLink and collect patient outcomes for: rate of unscheduled visits, rate or rehospitalization and length of stay, rate of qualifying AE and HF-related AE's, subject quality of life, and Patient & Physician satisfaction survey
Up to 12 months post-implant

Study Major Dates

Study Start (Anticipated)

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.
May 1, 2021

Primary Completion (Anticipated)

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.
