Why the study?
Since 2015, the incidence and epidemiology of infective endocarditis have changed, and new diagnostic and treatment options have emerged requiring updated guidance.
This updated AHA scientific statement provides comprehensive, multidisciplinary guidance on the diagnosis and management of infective endocarditis.

“However, in the absence of randomised data specific to IE addressing whether the total duration of antibiotic therapy could be tailored to an individual patient's clinical response rather than fixed at a predetermined number of weeks, both the 2015 AHA scientific statement and the 2023 ESC guidelines continue to recommend up to 6 weeks of therapy for most left-sided IE cases. In fact, the persistence is still visible in the newest released scientific statement by the AHA, where the writing group again recommended a native valve antibiotic duration of 4 weeks, and a prosthetic valve duration of 6 weeks.”
“This latest scientific statement on infective endocarditis (IE) from the American Heart Association (AHA) emphasizes a multidisciplinary approach and incorporates advances in diagnosis and therapy since the last iteration in 2015 — such as non–culture-based pathogen identification, partial oral antibiotic therapy in stabilized patients, and long-acting injectable lipoglycopeptide therapy.”
Recommends multidisciplinary teams, advanced imaging, and partial oral therapy for endocarditis; extends 2015 AHA guidance with post-2015 trial data.
Since the publication of the 2015 American Heart Association scientific statement on infective endocarditis, its incidence has increased, its epidemiology has changed, and novel diagnostic and treatment options have become available. Updated case definitions, non-culture-based pathogen identification methods, and advanced multimodality imaging techniques have emerged. A randomized controlled trial of partial oral therapy published in 2019 may change the treatment landscape for the foreseeable future. Percutaneous mechanical aspiration of right-sided vegetations is being used in select patients with uncontrolled infection despite appropriate antimicrobial therapy. The importance of an endocarditis team has become increasingly recognized in the management of this life-threatening syndrome. Therefore, multidisciplinary experts in cardiovascular infections were commissioned to develop this updated scientific statement on the diagnosis and management of infective endocarditis.
