Left atrial myxoma and calcified aortic stenosis in a patient with syncope

A 59-year-old man who suffered several episodes of syncope had both calcific aortic stenosis and a left atrial myxoma. As syncope occurred during effort, rather than after postural changes, we believe that the symptom was caused by aortic stenosis. In fact the myxoma was only mildly obstructive both by haemodynamic measurements and at visual inspection at surgery.
