Cardiac transplantation in severely ill patients requiring intensive support in hospital
Insights
Cardiac transplantation offers excellent outcomes, with a 69% survival rate, especially when performed before end-stage renal failure necessitates dialysis. This procedure justifies the resources required for critically ill patients.
Area of Science:
- Cardiology
- Transplantation Surgery
Background:
- Cardiac transplantation is a critical intervention for end-stage heart failure.
- Patients requiring urgent transplantation often need intensive medical support.
- Outcomes are influenced by the patient's pre-operative condition, including renal function.
Purpose of the Study:
- To evaluate the outcomes of cardiac transplantation in a cohort of patients.
- To assess the impact of pre-transplant critical care on survival.
- To determine the long-term success rates and justify resource allocation for this procedure.
Main Methods:
- Retrospective analysis of 64 patients referred for cardiac transplantation between October 1984 and December 1986.
- Detailed review of pre-transplant interventions for 33 patients requiring urgent care.
- Tracking of post-operative survival and complications.
Main Results:
- Overall post-operative survival rate was 69% at a mean of 19.4 months.
- For patients not requiring renal dialysis pre-operatively, surgical survival was 85.5%.
- Twenty patients experienced a successful transplant outcome, with 18 alive and well between 10 and 33 months post-surgery.
Conclusions:
- Cardiac transplantation yields excellent results when performed before the onset of dialysis-dependent renal failure.
- The procedure is a viable and justifiable treatment for carefully selected, terminally ill cardiac patients.
- Investment in specialized care and staffing is warranted for successful cardiac transplant programs.
Abstract:
Sixty four patients were referred for cardiac transplantation from a single cardiac team at this hospital between October 1984 and December 1986. Of these patients, 33 were referred for urgent transplantation, all of whom required intensive treatment in hospital with intravenous infusions of cardiac drugs, intra-aortic balloon counterpulsation, peritoneal dialysis, ventilation, or any combination of these to sustain life. Of these 33 patients, six died while awaiting transplantation, one was removed from the waiting list for a transplant, and 26 received cardiac transplants. There were five deaths within 24 hours of operation and one death 10 days after the operation. Twenty of those who had surgery had a successful outcome of transplantation, but there was one late death 10 weeks postoperatively and a further death 31 months after surgery. Eighteen patients were alive and well 10 to 33 months (mean 19.4 months) after transplantation, with an overall survival rate after surgery of 69%. Provided that surgery can be performed before renal failure has progressed such that renal dialysis [corrected] is necessary, the results are excellent (surgical survival 85.5%) and, we believe, justify the expenditure and staffing requirements necessary to treat these terminally ill patients.
