The International Thoracic Organ Transplant Registry of the International Society for Heart and Lung Transplantation: Thirty-sixth adult lung and heart–lung transplantation Report—2019; Focus theme: Donor and recipient size match

Abstract

This thirty-sixth adult lung and heart–lung transplant report summarizes data from 69,200 adult lung and 4,128 adult heart-lung transplants performed through June 30, 2018 and reported to the International Thoracic Organ Transplant Registry. With each year's report, we now provide more detailed analyses on a particular focus theme important to patient outcomes. Since 2013, these have been donor and recipient age; retransplantation; early graft failure; indication for transplant; allograft ischemic time; and multiorgan transplantation. Although widely accepted as critical to decision making at the time of receipt of an organ donor offer, there is surprisingly little literature outlining current practice and the impact of size (mis-)matching on outcomes. Hence this year's report focuses on an overall theme of donor and recipient size matching. In addition to reporting donor and recipient height and weight difference for all adult lung and heart-lung transplant recipients stratified by transplant type (bilateral or single) and indication, we report historical trends and associations between size match and survival. The Registry's online slide sets include results from additional analyses and complementary information not included in this publication (see https://ishltregistries.org/registries/slides.asp ).
