Insights
Cleveland Clinic
Area of Science:
- Cardiology
- Transplantation Medicine
- Mechanical Circulatory Support
Background:
- Cleveland Clinic has performed over 1,600 adult heart transplants.
- The 2006 heart allocation system changes impacted transplant volume and recipient acuity.
- Left ventricular assist devices (LVADs) are increasingly used as a bridge to transplant.
Purpose of the Study:
- To evaluate outcomes in adult heart transplantation at Cleveland Clinic.
- To assess the impact of the 2006 allocation system changes.
- To review the role and advancements of mechanical circulatory support (MCS) in heart failure management.
Main Methods:
- Retrospective analysis of adult orthotopic heart transplant data.
- Review of patient outcomes including survival rates.
- Assessment of trends in MCS utilization and patient selection.
Main Results:
- 1-year survival is 96%, 3-year survival is 82%.
- Increased LVAD use as bridge to transplant has not compromised outcomes.
- LVADs are expanding to patients ineligible for transplant, with improving results.
Conclusions:
- Excellent outcomes are maintained despite changes in allocation and increased MCS utilization.
- LVAD technology is advancing, offering life-saving therapy to more patients.
- Further refinements in patient selection and management are needed for permanent MCS therapy.
Abstract:
The cardiac transplantation program at Cleveland Clinic has performed 1,627 adult orthotopic heart transplants, with a current 1-year survival of 96% and a 3-year survival of 82%. The change in the heart allocation system in 2006 has affected our Center by both reducing the number of transplants we perform annually and increasing the percentage of recipients on MCS at the time of transplant. Despite the increased utilization of left ventricular assist devices (LVADs) as a bridge to transplant, we continue to maintain excellent outcomes. The major clinical advances in LVAD technology have allowed us to expand this therapy to ineligible transplant patients, with outcomes that are continually improving. Nevertheless, the field of MCS as permanent therapy is still in its infancy. The number of patients who can benefit from this technology in the U.S. alone is in the thousands, but refinements in patient selection and management are needed to further advance this lifesaving therapy.
