Cardiac rhabdomyoma is a noncancerous tumor of the heart, a type of rhabdomyoma. It typically occurs within the ventricular muscle, and less frequently in the atria. It may present on routine ultrasound screening of the baby in a pregnant mother. There may be no symptoms or mild symptoms with a heart murmur. Tuberous sclerosis may be present in up to 70% to 90% of cases.
There typically several rather than just one tumor. Complications include abnormally beating heart and obstruction of blood flow from the heart. Diagnosis is by echocardiography. There is a possibility that the tumor disappears as the child gets older, without treatment. However, if symptoms or arrhythmia then cutting some of the tumor out, but preserving important heart structures, may be required. mTOR inhibitors may be considered.
More than 60% of heart tumors in children are of the cardiac rhabdomyoma type.
