Project My Heart Your Heart: Pacemaker Reuse (MHYH)

July 1, 2025 updated by: Thomas Crawford, MD, University of Michigan

Project My Heart Your Heart: Prospective Evaluation of the Safety and Efficacy of Cardiac Pacemaker Reuse in Low to Middle Income Countries

Lack of access to pacemakers is a major challenge to the provision of cardiovascular health care in Low and Middle Income Countries (LMIC). Post-mortem pacemaker utilization could be safe, efficacious, and ethically responsible means of delivering the needed care. Reconditioned pacemakers can provide therapy for patients with symptomatic bradycardia and no means of receiving a new device. The objective of the clinical trial is to determine if pacemaker reutilization can be shown to be a safe means of delivering pacemakers to patients in LMIC without resources. Consented patients in this multi-center trial will be randomized to undergo implantation of either a reconditioned device or a new device.

Study Overview

Status

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

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.

Enrollment (Estimated)

Enrollment

370

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Description

Inclusion Criteria:

  • Life expectancy ≥ 2 years.
  • Indications for device implantation must be fulfilled per standard of care. Consistent with 2008 American College of Cardiology / American Heart Association guidelines for device therapy, one of the following class I indications must be met.
  • Sinus Node Dysfunction
  • Acquired Atrioventricular (AV) Block
  • Chronic Bifascicular Block
  • Hypersensitive Carotid Syndrome
  • Lack of financial ability to pay for a new device must be assessed and documented.
  • All other methods of new device acquisition must be exhausted.
  • Patient must be agreeable and able to follow-up with the implanting center within 2 weeks for wound check, at 2 months, 6 months, and every 6 months thereafter for routine pacemaker checks.

Exclusion Criteria:

  • Severe valvular disease
  • Severe pulmonary disease
  • End-stage renal disease (creatinine clearance < 30 mL/min) whether or not on dialysis
  • Evidence of ongoing systemic infection
  • Prior pacemaker or implantable cardioverter-defibrillator implantation
  • Significant contraindication to pacemaker implantation per evaluation of the implanting physician (very high risk of complications).
  • Presence of any other condition that the local investigator feels would be problematic or would restrict or limit the participation of the patient for the entire study period
  • Pregnant women

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
Freedom from Procedure-Related Infection at 12 months
Time Frame: 12 months post device implantation
Clinical evidence of pacemaker infection includes local signs of inflammation at the generator site such as erythema, warmth, fluctuance, tenderness, purulent drainage, wound dehiscence, or erosion. Device related endocarditis will be reported if the Duke criteria for infective endocarditis are met. Procedure-related infections will be classified as follows: pocket infection, endocarditis, recurrent bacteremia, extrusion of wires or generator
12 months post device implantation

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
Freedom from Pacemaker Software or Hardware Malfunction at 12 months
Time Frame: 12 months post device implantation
Pacemaker software or hardware malfunction include unexpected premature battery depletion, device or electrode malfunction, or unexplained patient death.
12 months post device implantation
