IMAGE INTERPRETATION
Image 1: Subcostal view.
There is a whopping great big mass sitting in the left atrium. With each atrial contraction it moves forward and obstructs forward flow. This is causing pulmonary oedema – see the B-lines around the heart? She also had small pleural effusions.
Oh yes, and the other basic echo questions we should always ask – the RV looks OK, the LV if anything looks underfilled. Funny that. And there is no significant pericardial effusion.
She was admitted by cardiothoracics and taken to theatre.
Typically, myxoma manifest as a solitary, pedunculated, mobile mass in the left atrium (LA) with a stalk that is attached to the inter-atrial septum. Alternate diagnostic possibilities for left atrial masses include thrombus, lipoma, sarcoma and metastasis.

CLINICAL CORRELATION
Left atrial tumour – atrial myxoma
Popping the probe on to every patient you see with shortness of breath or chest pain sometimes reveals unanticipated findings.
