The finding of a cardiac myxoma usually implies immediate consequent surgical excision to prevent embolic events. Reports with documented growth rate are therefore very rare, and the actual growth rate remains a controversial issue. We report the growth of a left atrial myxoma in an asymptomatic 65-year-old patient with several years of follow up for aortic valve disease. A MEDLINE search with the terms "cardiac myxoma and tumor growth" was performed. The calculated growth rate showed an average growth rate of 0.49 cm/month. These reports suggest that the growth rate of myxomas may be faster than is usually thought.

We report a case of a 59-year-old woman with recurrent cerebrovascular insults caused by a papillary fibroelastoma of the aortic valve. Primary cardiac tumors are rare. Papillary fibroelastoma (PFE) is the most common valvular tumor and the second cardiac benign tumor after myxoma. The clinical presentation of PFE varies from asymptomatic to severe embolic complications. The tumor was surgically removed to avoid new embolic events.

We report an atypical echocardiographic presentation of a vegetation in a patient with late infective endocarditis of an atrial septal defect (ASD) occluder device. Transesophageal echocardiography demonstrated a penduculated mass attached to the left atrial side of the occluder device. This mass presented as an oscillating echo free area surrounded by a membrane attached to the device by a thin stalk. At time of surgical excision, the lesion did not present as a spherical cyst. It was assumed that the content of the echo free mass had already emptied into the left atrium. Histopathology diagnosed the mass as a vegetation. The contribution of contrast echocardiography to the evaluation of intracardiac masses is briefly discussed.
