Atrial Blood Cyst: A Rare Finding

Right Ventricular Blood Cyst Causing Outflow Tract Obstruction in an Adult

“…Although clearly the differential diagnosis includes other types of cardiac mass, the multimodality imaging approach used in this case has shown a predominantly cystic collection of blood which was not typical of a primary cardiac tumor 1,5 . Echocardiography and MRI prove to be helpful noninvasive imaging investigations and these have been reported to be the most accurate in determining the diagnosis.…”

“…Blood cysts were first reported by Elsasser in 1844. These masses are benign and predominantly originate from the atrioventricular and pulmonary valves 1 . They rarely originate from the right atrium or the right and left ventricles.…”

“…Blood cysts are benign intracardiac masses that can cause blood flow obstruction and subsequent hemodynamic as well as embolic symptoms. Although they are well described in infants, there is very little in the literature describing their incidence in adults 1‐3 . This report describes a symptomatic adult patient with a right ventricular blood cyst causing outflow tract obstruction, who underwent a successful surgical excision.…”

Endocardial Blood Cyst: A Rare Site and Age of Presentation

“…Cardiac blood cysts are rare benign endocardiac tumors (1.5% of all cardiac tumors), usually involving the cardiac valves 1,2 . They are more frequent in pediatric age, particularly in the first month of life, while are extremely rare in adults and to be found in positions other than the valvular apparatus 2,3 . They were first described by Elsässer in 1844 4…”

Blood Cyst of the Mitral Valve: A Rare Cause of Stroke

“…Resection is the treatment of choice for blood cysts causing outflow obstruction or embolic strokes. Routine removal of these cysts has also been suggested to rule out malignancy 9 …”
