Three Years’ Experience of the Infective Endocarditis Team in a University Hospital

Objective: Infective endocarditis is a serious disease with high morbidity and mortality due to serious embolic complications. The follow-up of the patients requires multidisciplinary evaluation. We aimed to share the experience of the infective endocarditis team in our hospital and to guide the work of the teams to be formed in the future. Methods: Our study was planned as descriptive, cross-sectional, and observational. The patients were diagnosed by the modified Duke criteria. The National Infective Endocarditis Consensus Report was considered during the diagnosis, follow-up, and treatment process. Results: Fifty (45.4%) of 110 patients followed by the team were diagnosed with endocarditis. Thirty of the patients (51.8%) were male, the median age was 63.5 (18-87) days, and the median duration of symptoms was 35.7 (1-180) days. 76% of the diagnoses were definite endocarditis, 46% of the cases had an acute course, aortic valve involvement was 38%, and native valve involvement was 60%; the most isolated agent was Stapyhylococcus aureus. Community-acquired infection was 46%. The most common predisposing factors were prosthetic heart valve (38%) and hemodialysis (46%). Fever was observed in 64% of the patients and dyspnea in 58%. The rate of detection of vegetation by transesophageal echocardiography was 68%. Brain, pulmonary embolisms, and spondylodiscitis were the most common complications. The median time for blood culture to become negative was 3 (3-15) days, the operation time for 15 patients was 8 (1-30) days, and the 30-day hospital mortality was 28%. A statistically significant correlation was found between mortality and the presence of previous endocarditis, ejection fraction below 50%, complication development, hospitalization in the intensive care unit, presence of thrombocytopenia, Charlson comorbidity index ≥5, and vegetation size ≥1 cm (p<0.05). We determined that the presence of previous endocarditis increased the risk of mortality 14 times (p=0.025). Conclusion: Mortality and morbidity rates can be reduced by detecting underlying diseases, controlling complications, applying early effective antibiotic and anticoagulant treatment, surgical interventions at the right time, and rapid supportive treatments for sepsis by teams formed with a multidisciplinary approach.
