“…2 In adults, cardiac blood cysts have been reported on the mitral valve, [2][3][4] papillary muscles, 5 right atrium, 6 right ventricle, 7 LV, 8 and the aortic, 9 pulmonic, 10 and tricuspid 11 valves. Reported complications include LV outflow obstruction, 5 occlusion of the coronary arteries, 6 valvular stenosis or regurgitation, [9][10][11] and embolic stroke. 12 The embolic risk of rapid pacing and TAVR in a patient with an intracardiac blood cyst is unknown.…”

B lood cysts of the heart are primary cardiac tumors that usually disappear by the age of 6 months and are rarely reported in adults. A blood cyst within the left atrium has to our knowledge never been reported. Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement in patients with severe aortic stenosis who are deemed to be inoperable or at high risk for surgery. The outcome of performing TAVR in the presence of an intracardiac blood cyst has not been reported in the medical literature.We present the case of a woman with symptomatic severe aortic stenosis who underwent TAVR, despite having a left atrial blood cyst that was found incidentally on transesophageal echocardiography (TEE). Case ReportIn January 2013, a 78-year-old woman with a history of hypertension, nonobstructive coronary artery disease, hypothyroidism, and tobacco abuse presented to her primary care physician with reports of excessive fatigue, chest pain, and dyspnea on exertion for the preceding 6 months, progressively worsening during the last 8 weeks. The patient denied any shortness of breath at rest, lower-extremity edema, orthopnea, paroxysmal nocturnal dyspnea, syncope, or palpitations. She had no recent history of hospitalizations for acute coronary syndrome, congestive heart failure, or arrhythmias; and no recent long-distance travel or infectious illness. She was not taking an anticoagulative medication. An outpatient echocardiogram revealed concentric left ventricular (LV) hypertrophy, preserved LV ejection fraction, mild aortic regurgitation, and severe aortic stenosis (a valve area of 0.9 cm 2 by continuity equation, a peak aortic valve gradient of 94 mmHg, and a mean transvalvular gradient of 51 mmHg). A computed tomogram of the chest with intravenous contrast showed no evidence of pulmonary embolus, but did show ground-glass opacities in both lungs and severe calcification of the aortic valve, coronary arteries, aortic arch, and ascending and descending segments of the aorta. A filling defect was noted within the left atrium and

“…However, the pathogenesis of a Eustachian valve cyst is presumed to be similar to that of a cardiac blood cyst (4). Cardiac blood cysts are benign cardiovascular tumors that are frequently found in the atrioventricular valves of newborn infants (6). There are two suggested mechanisms underlying cardiac blood cysts.…”

Intracardiac Eustachian Valve Cyst in an Adult Detected with Other Cardiac Anomalies: Usefulness of Multidetector CT in Diagnosis

We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cyst. Recently, we observed a Eustachian valve cyst diagnosed on MDCT showing a hypodense cyst at the characteristic location of the Eustachian valve (the junction of the right atrium and inferior vena cava). MDCT also demonstrated additional cardiovascular anomalies including atresia of the coronary sinus ostium and a persistent LSVC and bicuspid aortic valve.

“…Blood cysts are congenital echolucent blood-filled nodules located on the endocardium, particularly along the lines of closure of heart valves [13]. Mobile oval blood cyst can be attached to the right atrial wall causing right coronary occlusion or as a round cyst attached to the inter-atrial septum with a thin, demarcated wall and echolucent core [14,15]. …”

A 71-year-old woman presented with a right adnexal solid mass invading the right gonadal vein and inferior vena cava up to the hepatic veins revealed by CT and confirmed by MRI. A thin-walled cyst and a solid mass were unexpectedly found in the right atrium by transesophageal echocardiography (TEE) in the operating room. Using color Doppler and air bubbles as contrast material a circumscribed cyst was confirmed and localized close to the IVC. The cyst was connected to the mass in the inferior vena cava. The tumor, including the cyst, was removed without using cardiopulmonary bypass and described as a low-grade endometrial stromal sarcoma, a rare slowly growing tumor. This is the first TEE description of endometrial stromal sarcoma manifesting as a right atrial cyst.
