Abstract
Heart transplant is the gold standard treatment for patients with heart failure. The limitation to providing heart transplantation to patients suffering from end stage heart disease is the stable organ supply within the United States despite increasing demand. Transplant centers across the United States have begun to expand traditional cardiac donor selection metrics previously utilized. As a result, the use of extended criteria donors, such as older donors, those with longer ischemic times, and donors considered high risk has increased. Current guidelines suggest that coronary angiography be performed when evaluating a donor above the age of 45. Angiographic guidelines for evaluation of the donor heart are based specifically on age, with little evidence based guidance surrounding the use of angiography in a younger donor with comorbidities or increased risk behavior which may lead to premature coronary artery disease. Recently, we have seen an increase in younger heart donors, many of whom have succumbed due to drug overdose with ensuing high risk behaviors. Given the increased risk nature of these donors, consideration of performing coronary angiography is determined by clinical “gestalt” of the transplant center evaluating the heart for use, which may lead to underutilization of donor organs without evidence to support the practice. Here, we review the guidelines, literature, and controversy surrounding the use of coronary angiography in evaluating donor hearts for transplantation.
