A 35-year-old man presented with progressive exertional dyspnea (3 months) and syncopal attacks (1 week). He had tachypnea, tachycardia and hypotension. Examination revealed a mid-diastolic plop at the apex. Clinical suspicion was a left atrial mass with a ball valve-like mechanism (LA thrombus or LA tumors). Echo and cardiac MRIs with gadolinium enhancement (to differentiate between a tumor an...

Primary heart neoplasms are rare occurring with an estimated incidence of 0.0017-0.19%. Myxoma is the most prevalent primary heart tumor. The right atrium is an unusual localization, occurring only in 15-20% of myxoma cases. We report a rare case of a massive right atrial myxoma causing tricuspid valve obstruction and presenting as syncope and exertional dyspnea. This case illustrates the influ...

The patient was a 67-year-old woman with a history of worsening dyspnea over several months. Cardiac echocardiography showed a large, mobile left atrial myxoma. Emergency surgery was performed. Cardiac arrest occurred during repositioning of the heart to cannulate the inferior vena cava and transesophageal echocardiography revealed the large myxoma obstructing the left ventricle. Cardiopulmonar...

A large atrial myxoma, attached in an atypical location, was identified in the left atrium of a 70 year old patient. Although the tumour occupied a large part of the left atrium the patient remained in sinus rhythm and displayed no symptoms.

Left atrial myxoma could be a rare cause of cardiac arrest as this mass could impinge on the mitral orifice causing left ventricular inflow tract obstruction.

Myxoma, a rare type of intracardiac tumor, forms a very small percentage of the cardiac cases. Reports of biatrial myxoma are rarer, with cases of single tumor reaching both atria being more common. Here, we present an unusual case of two independently growing atrial myxoma in a 29-year-old female. We emphasize that early recognition of symptoms, confirmation of diagnosis by transesophageal ech...
