Cardiac Rhabdomyoma

Pediatric cardiac rhabdomyoma (CR) is a benign, congenital cardiac tumor that typically forms in utero. The most common presenting symptoms include arrhythmias and blood flow restriction, which can result in a reduction in peripheral pulses, cyanosis, shortness of breath, heart murmurs, and heart failure. CR is associated with tuberous sclerosis in over 90% of patients and presents with multiple benign tumors. It is typically diagnosed with echocardiography and MRI. Most CRs resolve on their own. In more severe cases, cardiac surgery may be necessary.
