Intracardiac blood cysts are rare congenital malformations most commonly located in the endocardium of semilunar or atrioventricular valves. They are predominantly seen in infants, especially below 2 months of age, and disappear spontaneously in the first 6 months of life making the detection of blood cysts a rare finding in the adult population. Although most patients are asymptomatic, they may occasionally present with obstruction, valvular dysfunction, or embolism. Herein, we present a 2.5-year-old female patient, who was successfully treated with surgical excision of an intracardiac blood cyst causing mild-to-moderate mitral regurgitation and obstruction.
