Among 3127 episodes of suspected infective endocarditis, the 2023 Duke-International Society for Cardiovascular Infectious Diseases clinical criteria showed an accuracy of 90% for infective endocarditis diagnosis. A new heart murmur was present in 690 (22%) episodes. Excluding imaging and surgical findings decreased the accuracy to 73%, while using the physical examination criterion slightly improved the accuracy to 78%.
