Title:          Transcatheter aortic valve replacement for acute aortic regurgitation due to Staphylococcus aureus infective endocarditis complicated with a perivalvular abscess: a case report
Subject:        DOI: 10.1093/ehjcr/ytad166; European Heart Journal - Case Reports, 7, 4, 2023-4-12.; Abstract:  Background: Infective endocarditis is a life-threatening disease associated with high mortality. Appropriate antimicrobial treatment and cardiac surgery, when indicated, are closely related to prognosis. When cardiac surgery is contraindicated, prognosis worsens dramatically. There is few data concerning the use of transcatheter aortic valve replacement after healed aortic valve endocarditis or during active IE. We present the first case report of a transcatheter aortic valve replacement implanted during antimicrobial therapy for a severely symptomatic acute aortic regurgitation due to an infective endocarditis complicated with a perivalvular abscess. Case summary: A 68-year-old man was admitted due to left hemiparesis and fever. An acute ischaemic stroke with haemorrhagic transformation was diagnosed. Blood cultures were positive for methicillin-susceptible Staphylococcus aureus and a transoesophageal echocardiogram revealed an aortic endocarditis with an acute severe aortic regurgitation and a perivalvular abscess. Urgent cardiac surgery was contraindicated due to intracranial haemorrhage. However, the patient developed refractory pulmonary oedema and haemodynamic instability. Despite the perivalvular abscess, a transcatheter aortic valve replacement was successfully performed 15 days after the diagnosis. Nine months after completing antimicrobial therapy, there were no signs of relapse. Discussion: Transcatheter aortic valve replacement could be considered in selected patients with symptomatic severe aortic regurgitation due to aortic infective endocarditis during antimicrobial therapy when cardiac surgery is contraindicated.
