Bileaflet Blood Cysts on the Mitral Valve in an Adult

Echocardiographic findings of tricuspid blood cyst mimicking bacterial endocarditis in a dairy cow

“…Large blood cysts can be found without any detrimental impact on cardiac function 15 or with small impairement of valvular closure. 12,13 Due to the absence of secondary cardiac pathology in the present case, it seems that these blood cysts, as previously reported in cattle, 5 were an incidental finding not related to the cause of the illness. This case suggests that valvular cysts could be smaller than their echocardiographic appearance suggests.…”

“…In the present case report, the ultrasonographic aspect of the affected leaflet was hyperechoic, which contrasts with the typical echocardiographic aspect of human blood cysts, despite similar histopathological structure that consists of an endothelial internal layer surrounding blood cells. 10,12,13,15 In humans, blood cysts typically have a cystic appearance with an anechoic content surrounded by a thin echoic wall. 12,13,15 The lesions can be better imaged using contrast echocardiography with intravenous agitated saline injection.…”

Small cystic structures could have been easily missed when performing echocardiography with a low-frequency phased array probe due to the side-lobe artefacts that commonly occur with these probes.…”

Rheumatic heart disease with a mitral blood cyst: three-dimensional echocardiographic imaging

“…Based on the above findings, a diagnosis of rheumatic heart disease (RHD) with severe aortic regurgitation and moderate mitral regurgitation with a blood cyst of the mitral valve was made. Blood cysts are congenital benign lesions that generally regress with age1 and hence are rarely seen in adults 2. Their coexistence with RHD has seldom been reported.…”
