Summary
Machine perfusion shows promise for preserving donor hearts, potentially extending preservation times and improving post-transplant function. This technique may expand the donor pool by enabling the use of more marginal organs.
Area of Science:
- Cardiology
- Transplantation Medicine
- Organ Preservation
Background:
- Current cardiac preservation for transplantation relies on static cold storage with crystalloid solutions.
- This method limits transport intervals and donor pool expansion.
- Machine perfusion, successful in kidney transplantation, is being explored for heart preservation.
Purpose of the Study:
- To review the current status of machine perfusion technology for cardiac preservation.
- To assess its potential benefits and challenges compared to traditional methods.
Main Methods:
- Review of recent experimental studies in animal models evaluating machine perfusion for cardiac preservation.
- Analysis of outcomes related to ischemic burden, preservation time, and graft function.
Main Results:
- Machine perfusion appears to reduce ischemic burden and may allow longer preservation times.
- Improved early ventricular function post-reperfusion has been observed.
- Better metabolic profiles were noted, but a risk of graft edema exists.
Conclusions:
- Experimental results suggest machine perfusion offers superior cardiac performance post-transplantation.
- This technology could expand the donor pool through use of expanded-criteria donors or resuscitation of injured hearts.
- Potential for procuring hearts after cardiac death donation is also indicated.
