Management of infective endocarditis and long-term outcomes of patients who underwent surgery: The fifteen-year experience of a tertiary care center

Infective endocarditis (IE) is still associated with severe complications and poor prognosis. The surgery of IE has various technical difficulties due to severe infection, inflammation of heart tissue, and systemic effects, so controversies continue about the optimal timing of operation. This study presents the treatment approaches, early and late-term outcomes of IE patients, who underwent surgery.This retrospective descriptive study is conducted with 46 patients (31males) operated between 2002-2018. The demographics and preoperative, intraoperative and postoperative data of patients were analyzed from the clinical database and patient records. Emergency surgery was performed to 15 (32.26%) patients.Numbers of patients with mitral valve, aortic valve, and prosthetic valve endocarditis were 14, 25, 7 respectively. Aortic valve replacement (AVR), mitral valve replacement (MVR), MVR + AVR and mitral valve repair were performed in 24, 12, 8 and 2 patients, respectively. Additionally, peri-cardial patch repair (periannular abscess or damage (n=12), aorta-right atrial fistulae (n=3)), debulking of associated tricuspid valve vegetation (n=2), tricuspid De Vega annuloplasty (n=3), Bentall operation (n=1) and aortic root enlargement (n=5) were performed. The mean follow-up period and mortality rates were 24.86 ± 38.98 months, 13.04% respectively. The mean survival and reoperation-free time were 179.02 ± 13.78 and 203 ± 10.09 months, respectively. Patients can be managed appropriately with early diagnosis, aggressive medical and surgical treatment via a multidisciplinary approach with customized management according to guidelines in terms of individual characteristics. In cases of worsening hemodynamic status, uncontrolled infection, large and mobile vegetations surgery should be performed as soon as possible
