Abstract
Complete atrioventricular block (AVB) is one of the well described but uncommon complications of infective endocarditis (IE). The degree of AVB reflects the extension of infection. The degree of AVB is thought to be associated with increased morbidity and mortality. It is recommended to evaluate newly developed AVBs as predictors of IE, to diagnose and treat IE as soon as possible. We report a case with delayed diagnosis of aortic valve endocarditis that revealed first degree AVB in the earlier phase of disease and followed by complete AVB until accurate treatment was started. Successful surgical intervention and antibiotherapy resulted in a downgrading and diminishing of the high-grade conduction block without any complications
