The initial transthoracic echocardiography revealed a thickened aortic root. An abscess formation was visualized upon subsequent three-dimensional transesophageal echocardiography and positron emission tomography/computerized tomography (PET/CT). The patient underwent an urgent necrotic tissue debridement and a redo Bentall surgery. The real-time polymerase chain reaction of excised tissues was positive for <i>Streptococcus</i>.<h4>Clinical discussion</Annals of medicine and surgery (2012)104238https://www.ebi.ac.uk/biostudies/studies/S-EPMC9422276biostudies-literatureMultimodality imaging in the diagnosis of bioprosthetic aortic valve endocarditis: A case report.PMC9422276Bui STTVu TTPhan NTDuong HDNguyen HTTNguyen AVMai SHfalseMultimodality imaging in the diagnosis of bioprosthetic aortic valve endocarditis: A case report.<h4>Introduction</h4>Prosthetic valve infective endocarditis (PVE) is a diagnostic challenge even in the era of multimodality cardiovascular imaging.<h4>Case presentation</h4>The patient was a 67-year-old male with a three-year history of bioprosthetic aortic valve replacement who presented with persistent fever and negative blood cultures.
