Since microbial gene sequencing was utilized for etiologic diagnosis of culture-negative endocarditis, cases of Bartonella endocarditis have been reported in various countries. Herein we report the first case of Bartonella quintana endocarditis, which was confirmed for the first time in Korea by 16S rRNA gene sequencing from the excised valve. A 75-yr-old woman was hospitalized due to dyspnea. ...

Forty-seven echocardiograms were obtained in 32 patients with bacterial endocarditis. Preexistent abnormalities were found in 14 patients. In five of them thought to have bacterial endocarditis on normal valves, echocardiography showed mitral stenosis (one), bicuspid aortic valve (two), and prolapse of mitral valve (two). Definite vegetations were seen in 22 patients on the aortic valve in seve...

We report the first feline case of Bartonella henselae endocarditis. Despite negative blood cultures, the cat had high Bartonella antibody titers and B. henselae type I DNA was detected in the damaged aortic valve. Microscopic examination of the valve revealed endocarditis with small silver positive coccoid structures in endothelial cells.

Cardiobacterium valvarum was isolated from the blood of a 71-year-old man with fatal aortic valve endocarditis. The API NH system was used for phenotypic characterization of the C. valvarum strain. This is the first case of infective endocarditis caused by C. valvarum in Germany and the first case worldwide affecting a prosthetic valve and lacking an obvious dental focus.

This report describes the echocardiographic features seen in a case of bacterial endocarditis in which the aortic valve leaflets had been partially destroyed. The echocardiogram demonstrated unusual, disorganized echo patterns in the outflow tract of the left ventricle near the anterior leaflet of the mitral valve in diastole. These were shown to be continuous with similar disorganized echo pat...

High mortality associated with pneumococcal endocarditis is due to late diagnosis and the frequency of complications, which usually require early diagnostic and intensive therapeutic measures. We present the first reported case of pneumococcal endocarditis with simultaneous infection of an aortic prosthetic valve, native tricuspid valve, and permanent pacemaker lead.

We present a case of a 46-year-old man with advanced acquired immunodeficiency syndrome and congenitally bicuspid aortic valve endocarditis caused by methicillin- and gentamicin-resistant Staphylococcus aureus. Endocarditis led to root abscess formation, a complete heart block, and fistulous tract formation between the ascending aorta and the right ventricle. Although perivalvular abscess is no...

The echocardiographic abnormalities in five cases of aortic valve endocarditis are described and are correlated with the anatomical appearance of the valve at the time of aortic valve replacement. These echocardiographic findings are compared with those which have been reported previously in this condition. Thickening of the aortic leaflets in systole or multiple linear or coalescent aortic val...

The echocardiographic abnormalities in five cases of aortic valve endocarditis are described and are correlated with the anatomical appearance of the valve at the time of aortic valve replacement. These electrocardiographic findings are compared with those which have been reported previously in this condition.
