Role of Primary Bacterial Contamination of a Pulmonary Homograft for Ross Operation: Report of a Case and Review of the Literature

Abstract

In a 43-year-old female, Ross operation was performed with annular reinforcement of the autograft and a cryo-fixed homograft that proved to be contaminated with enterobacter cloacae and klebsiella pneumoniae at the time of operation. Clinical course was unremarkable, perhaps due to effective antibiotic prophylaxis and treatment. In the literature, little is known about intraoperative bacterial contamination and early endocarditis. The authors report what they believe is the second reported case. Particular resistibilities of homograft and autograft might make early endocarditis unlikely.
