Atrial myxoma should be considered and excluded by echocardiography in patients presenting with progressive exertional dyspnoea, even in the absence of typical cardiological signs.
Supports echocardiography to exclude myxoma in unexplained progressive dyspnoea; hypothesis-generating, should not yet change practice.
A 40 year old man suffered eight years of vague but disabling symptoms, initially thought to be related to post viral fatigue syndrome, but ameliorated by the removal of a large atrial myxoma. The diagnosis of atrial myxoma is notoriously difficult, but should be excluded by echocardiography if there are predominant symptoms of progressive exertional dyspnoea, even in the absence of cardiological signs.
