The artificial heart: infection-related morbidity and its effect on transplantation

Between October, 1985, and September, 1987, a total of 195 patients received cardiac allografts and 15 candidates required mechanical support with the Jarvik-7 total artificial heart. Seven of the 15 died within 60 days of total artificial heart implant. There have been no late deaths, and survivors are unrestricted. Six of 7 deaths were related to infection (mediastinitis, 5; pneumonia and sepsis, 1), and the remaining 1 was due to failure of the transplanted heart. Respiratory tract infection occurred in each of the recipients who died with infection, and the same organisms appeared to be related to subsequent mediastinitis in 3 patients (Serratia marcescens, 2; Pseudomonas, 1) and caused fatal sepsis in another (Enterobacter aerogenes, Candida albicans). One patient died with pneumonia and sepsis prior to transplantation, and another succumbed with mediastinal infection known to be present before transplantation.
