Insights
Combined heart and kidney transplants show similar survival and rejection rates to heart transplants alone. A staged surgical approach is recommended for these complex procedures.
Area of Science:
- Cardiology
- Nephrology
- Transplantation Medicine
Background:
- Combined heart and kidney transplantation is becoming more common.
- There is a lack of established guidelines for indications, contraindications, and surgical sequencing.
Purpose of the Study:
- To evaluate the outcomes of combined heart and kidney transplantation compared to heart transplantation alone.
- To assess the safety and efficacy of combined heart and kidney transplantation.
Main Methods:
- Single-centre retrospective analysis of 30 consecutive patients undergoing combined heart and kidney transplant.
- Comparison of outcomes with a cohort of patients who underwent heart transplant alone.
Main Results:
- Patients in both groups had similar preoperative characteristics.
- Combined heart and kidney transplant demonstrated comparable long-term survival rates.
- Low rates of cellular rejection and antibody-mediated rejection were observed in the combined transplant group.
- No significant differences in outcomes were noted based on preoperative patient characteristics.
Conclusions:
- Combined heart and kidney transplantation is a viable option with outcomes similar to heart transplantation alone.
- The staged surgical approach is suggested as the preferred method for combined heart and kidney transplantation.
Abstract:
Combined heart and kidney transplantation is increasing in frequency but there are no guidelines to establish the indications, contraindications and sequence for this surgical procedure. We report our single-centre experience on 30 consecutive patients who underwent combined heart and kidney transplant in comparison with heart transplant alone. Patients had similar preoperative characteristics in both groups. Combined heart and kidney transplant is associated with the same long-term survival rate, low cellular rejection and antibody-mediated rejection rates when compared with heart transplant alone. We did not observe any difference in the outcomes related to preoperative patient characteristics. We suggest the staged surgical approach as the preferred method for transplant.
