Objective  To investigate the knowledge level of Chinese cardiac surgeons regarding the management of infective endocarditis (IE), in order to identify the gap between clinical practices and the latest guidelines, and provide evidence-based support for improving the clinical management of IE. Methods  A nationwide survey was conducted through an online questionnaire from December 5, 2024, to December 31, 2024. Descriptive analysis of the survey data was performed. Results  A total of 67 valid responses were received from 18 provincial-level administrative divisions across China. While 56.7% (38/67) of respondents demonstrated familiarity with the modified Duke criteria, only 43.3% (29/67) comprehended the 2023 Duke- International Society of Cardiovascular Infectious Diseases criteria. Conversely, 43.3% (29/67) exhibited limited understanding of the former, and 56.7% (38/67) showed deficient knowledge of the latter diagnostic standards. Only 46.3% (31/67) reported proficiency in current IE management guidelines/consensus. Regarding surgical timing, 26.9% (18/67) advocated intervention within 7-14 days of antimicrobial therapy, 22.4% (15/67) during 14-28 days, and 10.5% (7/67) beyond 28 days. Notably, a significant proportion of respondents opted for delayed surgical intervention beyond guideline recommendations when managing patients with heart failure, uncontrolled infection, or neurological complications. Conclusion  A knowledge gap and practice discrepancies exist among Chinese surgeons regarding the management of IE. There is an urgent need to promote updated concepts regarding surgical indications and timing for IE in order to optimize treatment strategies and improve patient prognosis.
