“…Intracardiac blood cysts are usually asymptomatic, small, and have congenital origin [2]. They often disappear with age [1], making the detection of such cysts in the elderly a rare finding.…”

“…Detection of larger cysts in adults is very rare since most of these cysts regress spontaneously. Although acquired blood cysts have been reported, a congenital origin has been described in most cases [2]. Most often, blood cysts are attached to cardiac valves or their supporting structures [3].…”

“…The presence of microbubbles inside the cystic cavity during diastole (confi rming the passage of blood between the ventricular cavity and the cyst lumen) has been described as a pathognomonic sign of the presence of a blood cyst [ 6 ]. The cyst is most commonly present at an atrioventricular valve; it occurs less often in semilunar valves and is also found at papillary muscle [ 7 ] or the atrialized right ventricular portion of Ebstein's anomaly. There is no consensus regarding optimal management of asymptomatic blood cysts.…”

A 59-year-old man presented with acute dysarthria and left hemiparesis, which lasted for 15 min and spontaneously resolved. He had no risk factors for cardiovascular diseases and had a negative family history for stroke or other premature cardiovascular diseases. Cardiac examination revealed a grade 3/6 systolic murmur at the left parasternal border. Learning PointsAlthough cardiac myxoma is the most common benign cardiac tumor, those that originate from the heart valve are rare [ 1 ]. Mitral valve myxoma, conventionally defi ned as a myxoma arising from the mitral leafl et, annulus, commissures, junction area, or subvalvular apparatus (chordae or papillary muscle), is considered rare, with up to 64 myxomas described in 42 articles from 2006 to 2011 [ 2 ]. This case represented a mitral valve myxoma originated from the papillary muscle and chordae, which is considered exceedingly rare. This case also highlights the role of multimodality imaging in diagnosis and treatment planning. Cardiac MRI provided complementary data on tissue characteristics of the tumor and anatomic defi nition for surgical planning (Figs. 13.1 , 13.2 , 13.3 , 13.4 , 13.5 , 13.6 , and 13.7 ). Cardiac myxomas that are located in the left ventricular chamber are associated with higher embolization risk, partly owing to higher mobility and left ventricular pressure [ 3 ], so surgical resection should be performed promptly once the diagnosis is established. Follow-up echocardiography should be performed to detect recurrence [ 4 ]. Video 13.1 Transthoracic echocardiography (TTE) parasternal long-axis view showed a 3.7 × 3.6-cm, highly mobile echodensity with frond-like projections in the left ventricle, attached to the posterior mitral valve leafl et and subvalvular apparatus (AVI 5351 kb) Video 13.2 TTE apical four-chamber view showed the mass ( arrows ) of the mitral valve (AVI 4775 kb) Cardiac Masses and Miscellaneous

“…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.…”
