Characteristics, management, and outcome of infective endocarditis in the Czech Republic: prospective data from the ESC EORP EURO-ENDO registry.

INTRODUCTION: Data describing contemporary profile of infective endocarditis (IE) in the Czech Republic are lacking. The aim of this study was to describe the current profile and outcomes of IE patients. METHODS: Prospectively collected data on consecutive patients admitted for IE diagnosis between April 2016 and March 2018 to 11 main tertiary care cardiac centers in the Czech Republic were used for this analysis. RESULTS: Among 208 patients, 88 patients (42.3 %) had native valve IE (NVIE), 56 patients (26.9 %) had prosthetic valve IE (PVIE), and 57 patients (27.4 %) had intracardiac device-related IE (CDRIE). The mean age was 61.66±15.54 years. Staphylococcus aureus was the most common etiological agent of IE (27.4 %), whereas Culture negative IE was present in 26.4 % patients. Surgery was performed during hospitalization in 112 (53.8 %) patients. In-hospital death occurred in 21.2 % patients, while 1-year mortality was 40.3 %. In patients, who had an indication for surgery, but the procedure was not performed, mortality was significantly higher (p=0.002). CONCLUSION: High proportion of culture negative IE and IE related to artificial intra-cardiac materials calls for action. Furthermore, we show that cardiac surgery should be more often contemplated, especially in the presence of risk factors as septic shock and congestive heart failure (Tab. 6, Fig. 1, Ref. 32).

Clinical predictors of complications in patients with left-sided infective endocarditis: A retrospective study of 206 episodes.

PURPOSE: Early identification of specific patient subgroups at high risk of developing life-threatening infective endocarditis (IE) complications is of paramount importance. Better stratification may allow more intensive treatment of these patients and positively influences clinical outcomes. METHODS: We carried out a retrospective survey of consecutive left-sided IE adult patients, admitted over a 15-year period to two main tertiary care centres in the Czech Republic. RESULTS: Among a group of 196 patients (155 males; median age 64 years), a total of 206 left-sided IE episodes were identified. Perivalvular extension of infection was most frequently seen in prosthetic aortic valve endocarditis (OR 6.706, p<0.0001). Valve prolapse/perforation during IE episodes was significantly associated with mitral valve IE (OR 2.136, p=0.026) and vegetation length (OR 1.055, p=0.009). Septic shock was significantly related to two main risk factors: S. aureus infection (OR 8.459, p=<0.0001) and smoking (OR 8.403, p=0.001). Mitral valve IE with a vegetation length ≥13 mm was the strongest risk factor for this complication (OR 3.24, p=0.001), followed by S. aureus infection (OR 3.59, p=0.002). Finally, septic shock (OR 6.000, p=0.001) represented the most important risk factor of in-hospital mortality. CONCLUSIONS: This study provides the most detailed profile of complication predictors related to left-sided IE in Central Europe. Early individual stratification of IE related occurrence of complications might help to decrease extremely high morbidity and mortality of this disease (Tab. 5, Ref. 37).
