Autopsy findings in cardiac transplant patients. A 10-year experience

Findings from 44 autopsy examinations of cardiac transplant patients during a 10-year period were reviewed. The autopsy rate was 85%. One half of the autopsy patients underwent original transplantation for ischemic heart disease and 34% for cardiomyopathy. Survival after transplantation ranged from 0 (intraoperative) to 91 months. Rejection (including hyperacute rejection) was responsible for 41% of deaths, followed by infection (25%), and intraoperative deaths at first transplantation (9%). Most of the remaining complications were related to surgery or artificial heart support, accelerated allograft atherosclerosis, and lymphoma. Infections were not only responsible for a substantial percentage of deaths but were also a co-morbid finding in a number of patients who died primarily of other causes. Pulmonary infections represented the most common anatomic site. Twenty-five percent of the autopsy patients had gastrointestinal and/or pancreatic abnormalities, principally mucosal inflammation, erosions or hemorrhage, and pancreatitis. Review of premortem rejection history indicated that 64% of patients who died of or with rejection at autopsy had had an episode of rejection 3 weeks after transplantation and/or at least one episode of severe rejection.
