چکیده
BACKGROUND Myxomas arising from the eustachian valve are exceedingly rare. CASE REPORT A 72-year-old Jamaican-Chinese woman was evaluated for worsening dyspnea. The 2-dimensional and real time 3-dimensional transesophageal echocardiogram showed a 75 mm length × 44 mm width, multilobulated, mobile mass arising from the eustachian valve occupying the entire right atrial and right ventricular cavities extending into the coronary sinus, right ventricular outflow tract, and proximal inferior vena cava. The patient underwent successful resection of the mass and replacement of the tricuspid valve. Histopathologic examination confirmed the diagnosis of atrial myxoma. CONCLUSIONS This is the largest myxoma found on a Eustachian valve.

Giant myxoma causing right ventricular outflow tract obstruction.
Atrial cardiac myxoma is the most common benign cardiac tumour. Atrial myxoma most commonly arises from the left atrium and, less frequently, from the right atrium or both ventricles. Cardiac myxoma arising from the tricuspid valve is rare. These tumours can present with right heart failure as a result of right ventricular outflow tract obstruction. A high index of suspicion and appropriate inv...

We describe a 56-year old male patient who presented with congestive heart failure and had undergone echocardiography that showed a mobile, giant left atrial mass which caused obstruction in the left ventricular outflow tract. The patient underwent a coronary angiography before operation that showed severe stenosis in the left anterior descending and circumflex artery. The patient underwent res...

the heart that occurs primarily in the left atrium. The clinical signs and symptoms may be nonspecific. The size of the lesion differs widely among patients but generally ranges from 2 to 6 cm. Depending on the size and location, it may cause mitral valve obstruction and pulmonary hypertension. We report a case of an unusually large left atrial myxoma in an 84-year-old woman that caused pulmona...
متن کاملTricuspid valve obstruction and right heart failure due to a giant right atrial myxoma arising from the superior vena cava
Myxomas are the most common primary cardiac tumors. The cardiac myxomas are mostly diagnosed within the atria, and only a few such tumors are reported to have arisen from atrioventricular valves or pulmonary vessels. The authors here present a case of 59-year-old Chinese woman who was hospitalized for exacerbating symptoms of tricuspid stenosis and right heart failure. Echocardiography revealed...
متن کاملGiant Left Atrial Myxoma: Cause for Position-Dependent Nocturnal Dyspnea and Cardiac Murmur
Primary tumors of the heart are rare. The majority of them are benign, the left atrial myxoma being the most frequent one. Clinical appearance varies from unapparent to life-threatening complications such as stroke, acute heart failure, or even sudden death. Diagnosis and consecutive surgical treatment strongly depend on the clinical symptoms, but their extent does not correlate with the risk f...
