The assessment and selection of patients for heterotopic heart transplantation
Insights
Heterotopic heart transplantation offered a chance for end-stage heart disease patients, but donor availability and rejection posed significant challenges. Many patients died awaiting transplants, and successful outcomes were limited by irreversible rejection.
Area of Science:
- Cardiology
- Transplantation Surgery
Background:
- End-stage heart disease necessitates advanced treatment options.
- Heterotopic heart transplantation is a viable, albeit complex, surgical intervention.
Purpose of the Study:
- To evaluate the outcomes of heterotopic heart transplantation.
- To identify challenges and success rates in a specific patient cohort.
Main Methods:
- Retrospective analysis of 34 patients assessed for heterotopic heart transplantation between 1979-1980.
- Categorization of underlying myocardial diseases and patient management decisions.
Main Results:
- Ischemic heart disease was the most common indication (19/34 patients).
- Fifteen patients underwent transplantation, with 11 surviving the study period.
- Eight patients had functioning grafts; three experienced irreversible rejection.
Conclusions:
- Heterotopic heart transplantation can be life-saving but faces challenges.
- Donor organ scarcity and graft rejection significantly impact long-term success rates.
Abstract:
In the 2-year period 1979-1980, 34 patients were assessed at Groote Schuur Hospital as candidates for heterotopic heart transplantation. Ischaemic heart disease was the most common underlying cause (19 patients), with cardiomyopathy (9), rheumatic heart disease (2), failed transplants (3), and endomyocardial fibrosis (1) as the other causes of myocardial disease. Five patients were not accepted into the transplant programme, 2 declined after being accepted, and in 3 the initial decision of acceptance was later reversed. Nine patients died while awaiting suitable donors, the mean survival time from the date of acceptance being only 26 days. Fifteen patients underwent heterotopic heart transplantation, 11 remaining alive at the end of the period of study; 8 had normally functioning donor hearts but 3 had suffered irreversible rejection and awaited a second transplant.
