Dr. Ana Maria Rosales: In tuberous sclerosis, one of the clinical features is the presence of masses in the heart. These are called rhabdomyomas. They can appear as early as twenty-six weeks of estimated gestational age in the fetus. These are images taken from an echocardiogram to show the rhabdomyomas. The first picture over here is a cut of the heart from this side and the lower chamber of the heart, which is the ventricle. And right here there is an area that is bright, and corresponds to a rhabdomyoma. This is a picture seen from the front of the heart, and the heart is cut right through the front. This is that same lower chamber of the heart, but it's a frontal view. And once again you see this image here that is relatively bright compared to rest of the tissue, and that's a rhabdomyoma. This mass, although prominent, is not significant. It's not obstructing any blood flow. Is not causing absolutely any symptoms. And I expect that this will regress with time and disappear. Rhabdomyomas rarely may cause problems. It depends of course on the size, the number, the location of the tumors. Now the prognosis is very good. They do not metastasize. They do not become malignant, and the majority of them regress or disappear during infancy.
