Neonatal multiple blood cysts of heart valves

Incidental Finding of a Tricuspid Valve Cyst in a Patient with a Ventricular Septal Defect

“…Intracardiac cysts of the heart valves are uncommon but have been reported, usually as blood cysts or rarely as bronchogenic/entodermal inclusion cysts [1,4,5]. Although clear/serous cysts of the heart valves have been reported in large mammalian species, an exhaustive literature search revealed no reported case of a clear/serous valvar cyst in a human subject [3].…”

“…Although clear/serous cysts of the heart valves have been reported in large mammalian species, an exhaustive literature search revealed no reported case of a clear/serous valvar cyst in a human subject [3]. In the literature, it has been frequently stated that blood cysts on heart valves are common, especially in fetuses and infants; however, an investigation of 13,978 autopsy records was reviewed during a 10-year period (2387 fetal/perinatal/neonatal, 1505 adult, and 10086 forensic cases which were mainly adults) wherein no blood cysts were found [1]. Another smaller autopsy study showed congenital blood cysts of the heart valves were a common finding in neonates, found in 47% of neonates ranging in age from 26 weeks gestation to 11 months [2].…”

“…Tricuspid valve cysts are a rare entity, with most reports in the literature involving what is commonly known as "blood cysts" [1]. Blood cysts of the heart are benign primary cardiac tumors derived from enlargement of valvular blood and lymphatic vessels which usually disappear by 6 months of age [2].…”

An Unusual Cardiac Mass Associated with Severe Tricuspid Valve Regurgitation: Bloodcyst

“… 1 Blood cysts (BCs) have been considered as rare benign cardiac tumors mostly associated with the enlargement of blood and lymphatic vessels in the valvular structures. 2 Histopathologically, they are characterized by blood-filled spaces covered by thin layers of flattened endothelium and fibrous tissue. 3 Even though these valvular masses are mostly asymptomatic, they occasionally reach considerable sizes in adults and induce a variety of symptoms mostly attributable to the dysfunction of the involved valve, transvalvular obstruction, as well as systemic or pulmonary embolism.…”
