Ventricular assist devices (VADs) offer a chance for long-term survival in critically ill cardiac patients. Early VAD use, biventricular support, and experienced operators improve outcomes, despite high initial mortality.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Mechanical Circulatory Support

Background:

  • Ventricular assist devices (VADs) are used when conventional therapies fail.
  • High hospital mortality rates are associated with VAD implantation.

Purpose of the Study:

  • To identify factors associated with improved survival in patients receiving VADs.
  • To evaluate the long-term outcomes of VAD support.

Main Methods:

  • Retrospective review of 43 patients undergoing VAD implantation over 6 years.
  • Analysis of patient demographics, clinical variables, and outcomes.

Main Results:

  • Hospital mortality was 72%, with 28% discharged and surviving 9-62 months.
  • Early VAD institution, biventricular support, VAD as bridge to transplantation, and operator experience improved survival.

  • Younger age (<60 years) and preoperative myocardial infarction with shock were linked to better survival.

    • Conclusions:

    • VADs can provide long-term survival for select patients who would otherwise die.
    • Recommendations include VAD trials for patients failing cardiopulmonary bypass, perioperative deterioration, or as a bridge to transplantation.
    • Long-term survival depends on VAD complications and myocardial function.
