Multimodality diagnosis and surgical management of prosthetic valve endocarditis complicated with perivalvular abscess formation

Periannular extension of infection is a rare but potentially fatal complication of infective endocarditis. The accurate detection and delineation of periannular complications are crucial in patient management, which may also provide guidance for surgical interventions. Potential complications from a periannular extension of infective endocarditis include periannular abscess, pseudo-aneurysm formation, and subsequent development of aortocavitary fistula. Here, we present a case of a 46-year-old man with prosthetic aortic valve endocarditis complicated with perivalvular abscess formation that was managed with aortic homograft implantation.
