Insights
Heart transplantation relies on effective organ preservation. Cold cardioplegic arrest ensures good primary graft function, but minimizing ischemia time is crucial for optimal outcomes in cardiac disease treatment.
Area of Science:
- Cardiology
- Transplant Surgery
Context:
- Orthotopic heart transplantation is a standard treatment for end-stage cardiac disease.
- Evaluating graft function is critical for transplant success.
Purpose:
- To assess primary graft function after heart transplantation.
- To analyze the impact of ischemia time on graft function.
Summary:
- This study evaluated 108 heart transplantations using cold cardioplegic arrest for organ preservation.
- Mean ischemia times were 41 min (local), 98 min (distant <100 km), and 114 min (distant >100 km).
- Higher ischemia times correlated with increased need for catecholamine treatment and elevated creatinine kinase levels, though all grafts recovered well.
Impact:
- Cold cardioplegic arrest provides good primary graft function in heart transplantation.
- Shorter ischemia times are associated with better post-transplant graft performance.
- This technique supports successful outcomes in cardiac allograft recipients.
Abstract:
The orthotopic heart transplantation is an accepted treatment for terminal cardiac disease. The technique of heart procurement and preservation is explained and the primary graft function in 108 subsequent heart transplantations is assessed. The mean ischemia time is 41 +/- 10 min in local, 98 +/- 19 min in distant (< 100 km) and 114 +/- 16 min in distant (> 100 km) organ procurement. Our method of preservation consists of cold cardioplegic arrest with potassium (30 mEq/L) cardioplegic solution. The incidence of the indication for high dose katecholamine-treatment after surgery and the maximal creatininekinase levels rose with ischemia time. All hearts recovered within a few days and the stay in the intensive care unit was not prolonged. We conclude that the heart preservation with cold cardioplegic arrest results in a good primary graft function. It is important to keep the ischemia time as short as possible.
