Left atrial myxoma with aortic regurgitation.
A 59-year-old woman with a left atrial myxoma was shown to have moderate aortic regurgitation. At operation for removal of the myxoma it was found to be attached to the atrial septum close to the aortic root. It is suggested that the aortic regurgitation was caused by distortion of the aortic root caused by traction upon it from the myxoma as it moved downward into the left ventricle in diastole. Observations are made on the echocardiographic findings which helped in the diagnosis of the left atrial myxoma.
