Detection of Right-Sided Endocarditis in Children with Congenital Heart Disease by Two-Dimensional Echocardiography

Abstract

Right-sided endocarditis is rare in children. Since the clinical picture is nonspecific and the frequency of sterile blood cultures is high, the clinical and laboratory diagnosis is difficult. Recent reports suggest that echocardiography is a useful method to detect the presence of right-sided endocarditis. We studied 8 patients with congenital heart disease and right-sided endocarditis detected by two-dimensional echocardiography. All the patients were shown to have one or more vegetations in the two-dimensional echocardiographic examination. The 4 patients who did not respond to antibiotic therapy underwent elective cardiac surgery. One of these patients additionally had recurrent emboli to the lungs. Another of these 4 patients died during surgery due to myocardial failure. Apart from these 4 cases, urgent surgical intervention had to be carried out in 2 cases because of very large vegetative masses. Surgical confirmation of the diagnosis was available in all 6 cases. According to these results, we can conclude that two-dimensional echocardiography assumes a specific diagnostic role in cases with right-sided endocarditis. © 1990, International Heart Journal Association.
