- Abstract
The feasibility and durability of mitral valve (MV) repair in active infective endocarditis (IE) has been reported, but proper management of perioperative neurological complications and surgical timing remains uncertain and may crucially affect the outcome.In this single-center retrospective observational study, patients who underwent isolated MV surgery for active native IE in our institution between August 2005 and August 2015 were reviewed and analyzed. Patients who were operated on for healed IE or who required combined procedures were excluded from this study.A total of 71 patients were enrolled in the study with a repair rate of 53.5% (n = 38). Isolated posterior leaflet lesion was found in 15 patients (21%) and was related to higher reparability (86.7%, P = .004). The overall in-hospital mortality was 10 (14.1%): 3 (7.9%) in the repair group and 7 (21.2%) in replacement group (P = .17). Prognosis was not related to age, preoperative renal function, cerebral emboli, or duration of antibiotics. The only significant predictor was postoperative intracranial hemorrhage (ICH) [odds ratio 14.628 (1.649-129.78), P = .04]. At a mean follow-up period of 43.1 months, neither recurrent endocarditis nor late cardiac death was observed in both groups.Surgical timing and procedural options of MV surgery in active native IE did not make any difference, but occurrence of ICH after surgery jeopardized the final outcome. Routine preoperative brain imaging to detect silent ICH or mycotic aneurysm and aggressive treatment of these lesions may prevent catastrophe and optimize the results.
