Intraoperative diagnosis of mitral valve endocarditis secondary to Paenibacillus provencensis

Abstract

We report the first case of infective endocarditis caused by Paenibacillus provencensis. A mitral valve vegetation was incidentally discovered by intraoperative transoesophageal echocardiography in a 70-year-old woman undergoing aortic valve replacement. The precise identification of the causative agent was by means of genotypic characterisation with 16S rDNA gene sequencing. The patient was successfully treated with a 6-week course of antibiotics postoperatively, following debridement of the valve vegetation.

Keywords: Bacterial endocarditis; Cardiac surgery; Mitral valve; Paenibacillus provencensis.
