Right-side infective endocarditis: discrepancy between clinical and echocardiographic evolution: case report

Infective endocarditis is a relatively rare disease in clinical practice, with significant morbidity and mortality despite the improvements on its diagnosis and treatment. It is often difficult to identify its complications and define strategies for them. Dissociation between the clinical evolution and the findings from complementary tests (especially echocardiographic tests) is common. Clinical decisions become even more difficult when there are atypical manifestations of the disease, such as right-side endocarditis. This report is about a rare case of right-side endocarditis in a patient with chronic renal disease, in which there was a contradiction between worsening of the echocardiographic findings and clinical improvement. This situation may lead to difficulties regarding the criteria for indicating surgery and the safety of conservative clinical treatment.
