Background: Endocarditis associated with ring abscess is a pathology with high morbidity and mortality. Aim of the study: The purpose of this study was to analyze hospital mortality risk factors in patients with ring abscess due to endocarditis. Methods: From January 1982 to December 2000, 104 patients underwent surgical intervention at the Heart Institute of the University of São Paulo Medical School for valve endocarditis with ring abscess. The age ranged from 6 years to 73 years, with an average of 40.3 years and 72.1% were male. According to NYHA functional class (FC), 12 (11.5%) were in FC II, 62 (59.6%) in FC III, and 30 (28.9%) in FC IV. Seventy‐seven (74.0%) patients had endocarditis on a bioprosthesis, 58 (55.8%) in the aortic position and 19 (18.3%) in the mitral position. Twenty‐nine (26.9%) patients had atrioventricular blockage prior to the operation. Univariate analysis was performed comparing variables and hospital mortality with a level of significance of 5%. Multivariate analysis was performed by logistic regression. Results: The hospital mortality was 19.2% (20 patients). Univariate analysis showed that atrioventricular blockage, age, and prosthetic valve endocarditis significantly influenced hospital mortality. Multivariate analysis identified atrioventricular blockage as an independent predictor of hospital mortality. Conclusions: Preoperative atrioventricular blockage is an independent risk factor for hospital mortality in the surgical treatment of endocarditis with ring abscess.
