Differences in mortality in patients undergoing surgery for infective endocarditis according to age and valvular surgery

Abstract Background Infective endocarditis (IE) is associated with high mortality. Surgery may improve survival and reduce complications, but the balance between benefit and harm is difficult and may be closely related to age and type of surgical intervention. We aimed to examine how age and type of left-sided surgical intervention modified mortality in patients undergoing surgery for IE. Methods By crosslinking nationwide Danish registries we identified patients with first-time IE undergoing surgical treatment 2000–2017. Patients were grouped by age 75 years, respectively. Mortality at 90 days were 7.5, 13.9, and 22.3% (p
