Objective To study the relationship between the timing of surgery and one-year outcome in patients with infective endocarditis. Methods We retrospectively analyzed the clinical data of 97 patients suffered from leftside native valve infective endocarditis with neoplasm, admitted in Shanghai First People's Hospital between January 2000 and December 2011. There were 65 males and 32 females with mean age of 55.2±16.3 years (ranged 29 to 75 years). They were divided into two groups according to whether the surgery was performed within a week after diagnosis. The in-hospital mortality and one-year mortality, embolism and re-infection were calculated and compared between the two groups. Results There was no significant difference in the in-hospital mortality between the early surgery group and the conventional surgery group (1.9% versus 6.7%, P=0.241). While there was a significant difference in the rate of inhospital embolism related complications (1.9% versus 13.3%, P=0.030) between the two groups. There was no significant difference in one-year mortality between the two groups (1.9% versus 8.9%, P=0.122). The incidence rate of embolism related complication was 5.8% in the early surgery group and 20.0% in the conventional surgery group with a statistical difference (P=0.034). There was one patient with recurrent cerebral infarction among the 11 patients of cerebral infarction in the early surgery group,while 6 recurrent patients in the 9 patients with cerebral infarction in the conventional surgery group (9.1% versus 66.7%, P<0.005). Conclusions Early surgery in patients with left-side native valve infective endocarditis can't reduce the in-hospital mortality and one-year mortality but does decrease embolic events significantly. Early surgery is feasible in the patients with cerebral infarction.
