Long-term mechanical circulatory support offers a safe and reliable option for patients awaiting heart transplantation. Devices demonstrated effectiveness in supporting patients for over 100 days, with many successfully transplanted.

Area of Science:

  • Cardiology
  • Biomedical Engineering

Background:

  • Increasing heart transplant waiting lists necessitate advanced long-term mechanical circulatory support.
  • Mechanical circulatory support devices are crucial for managing end-stage heart failure.

Purpose of the Study:

  • To evaluate the outcomes of patients receiving long-term mechanical circulatory support (MCS) for over 100 days.
  • To assess the safety and reliability of different MCS devices in a patient cohort.

Main Methods:

  • Retrospective analysis of 20 patients (15 male, 5 female, aged 15-66) supported with MCS for >100 days (Sept 1987 - Aug 1996).
  • Devices used included Novacor IVAD, Thoratec system, and HeartMate.
  • Indications included bridging to transplant (17), myocarditis (2), and postcardiotomy cardiogenic shock (1).

Main Results:

  • Mean support duration was 178.1 days.
  • 15 patients (75%) were successfully transplanted, with 14 discharged.
  • The most frequent complication was device-related infection (11 patients).

Conclusions:

  • Mechanical circulatory support devices are safe and reliable for supporting patients long-term (>100 days).
  • MCS provides a viable bridge to heart transplantation for critically ill patients.
