BACKGROUND: Surgical treatment for endocarditis patients with a perivalvular abscess is still challenging.Methods and Results: From 2009 to 2016, 470 patients underwent surgery for active endocarditis at 11 hospitals. Of these, 226 patients underwent aortic valve surgery. We compared the clinical results of 162 patients without a perivalvular abscess, 37 patients who required patch reconstruction of the aortic annulus (PR group) and 27 who underwent aortic root replacement (ARR group). Patients with a perivalvular abscess had a greater number ofStaphylococcusspecies and prosthetic valve endocarditis, a greater level of inflammation at diagnosis and symptomatic heart failure before surgery, especially in the ARR group. Nevertheless, the duration between diagnosis and surgery was similar, because of a high prevalence of intracranial hemorrhage in the ARR group. Hospital death occurred in 13 (9%) patients without a perivalvular abscess, in 4 (12%) in the PR and in 7 (32%) in the ARR group. Postoperative inflammation and end-organ function were similar between the groups. Overall survival of patients without a perivalvular abscess and that of the PR group was similar, but was significantly worse in the ARR group (P=0.050, 0.026). Freedom from endocarditis recurrence was similar among all patients. CONCLUSIONS: Patients treated with patch reconstruction showed favorable clinical results. Early surgical intervention is necessary when a refractory invasive infection is suspected.
