Abstract

Purpose of review

As the number of people living with heart failure continues to grow, future treatments will focus on efficient donor organ donation and ensuring safe and durable outcomes. This review will focus on organ procurement, graft surveillance and emerging therapies.

Recent findings

Preliminary studies into donation after cardiac death have indicated that this may be an effective means to increase the donor pool. Novel preservation techniques that include ex-vivo perfusion to improve donor metabolic stabilization prior to implantation may also expand the donor pool. Biomarkers, including circulating-free DNA, are emerging that could replace the endomyocardial biopsy for acute graft rejection, but we lack a risk predictive biomarker in heart transplantation. Novel immune suppressants are being investigated. Emerging therapeutics to reduce the development of chronic allograft vasculopathy are yet to be found.

Summary

This review highlights the most recent studies and future possible therapies that will improve outcomes in cardiac transplantation. Larger clinical trials are currently taking place and will be needed in the future to develop and sustain current trends toward better survival rates with cardiac transplantation.
