Acinetobacter endocarditis: a rare nosocomial infection of native heart valves


Acinetobacter baumannii is an opportunistic bacterial pathogen predominantly associated with hospital-acquired infections. Here we present a case of infective endocarditis of native Mitral and Aorta valves caused by A. baumannii in a 73-year-old man. He underwent surgical excision and Pathologic specimen showed A. baumannii growth after 48 hours that was extensively drug-resistant (XDR). He was treated with colistin and tigecycline. Finally, he discharged with no important complication. To our best knowledge, it is the first case of Acinetobacter endocarditis has ever been reported in Iran. Although XDR A. baumannii is a life-threatening pathogen, proper and timely treatment can be life-saving.
