  • Title: Right-sided infective endocarditis: an echocardiographic study.
    Author: Sheikh MU, Ali N, Covarrubias E, Fox LM, Morjaria M, Dejo J.

    Abstract:
    Echocardiographic observations are described in 10 patients with right-sided bacterial endocarditis. Six of the nine patients with tricuspid regurgitation had shaggy echoes on the tricuspid valve, which were confirmed to be vegetations on autopsy in two patients. In six patients, right ventricular dilatation was present, and paradoxic septal motion was seen in four. In one of the patients with pulmonic valve endocarditis, the pulmonic valve and right ventricular outflow tract revealed the shaggy echoes in diastole, along with systolic fluttering of the pulmonic valve, right ventricular dilatation and paradoxic septal motion. When the findings are supplemented to the clinical picture, echocardiography is found to be a useful noninvasive adjunct in the diagnosis of acute vegetative bacterial endocarditis involving the right side of the heart, especially if other clinical features, e.g., fever, leukocytosis and positive blood cultures are absent.
