Abstract

Abstract: Background: Congenital Heart Disease (CHD) predisposes to Infective Endocarditis (IE) Purpose: To characterize and to determine the prognosis of IE in this specific population. Methods: The ESC EORP EURO-ENDO study is a prospective international study in patients (n=3111) diagnosed with IE. In this pre-specified ancillary analysis, we aimed to describe adult patients with CHD (n=365, 11·7%) and compare them with patients without CHD (non-CHD, n=2746) in terms of baseline characteristics and 1-year outcome. Results: CHD patients (73% men, age 44·8±16·6 years) were younger and had less comorbidities. Of the CHD patients, 14% had a dental procedure in the 6 months before hospitalization versus 7% in non-CHD patients (p<0·001) and more often positive blood cultures for Streptococcus viridans (16·4% vs 8·8%, p<0·001). As in non-CHD patients, IE affected most often the left-sided valves. For CHD patients, in-hospital mortality was 9·0% vs 18·1% in non-CHD patients (p<0·001), and also 1-year outcome was more favourable (log-rank for all-cause mortality p<0·0001), even after adjustment for age (Hazard Ratio (HR) 0·61; 95% CI 0·45–0·81). Within the CHD population, multivariable Cox regression revealed the following predictors for mortality: fistula (HR 6·97), cerebral embolus (HR 4·64), renal insufficiency (HR 3·44), Staphylococcus aureus as causative agent (HR 2·06) and failure to undertake surgery when indicated (HR 5·93). Conclusion: CHD patients with IE have better outcome in terms of all-cause mortality. The observed high incidence of dental procedures prior to IE fuels the discussion about the need for antibiotic prophylaxis. FUNDunding Acknowledgement: Type of funding sources: Other.
