Two Cases of Tuberous Sclerosis With Multiple Rhabdomyoma Succumbing to Sudden Cardiac Death

Abstract

Tuberous sclerosis complex is an autosomal dominant condition with variable penetrance. It is characterized by tuberose deposits in various organ systems. Although clinical features predominate neurocutaneous manifestations, cardiac, kidney, and lung involvement are common. Cardiac involvement is marked by the presence of multiple rhabdomyomas and in some cases arrhythmias. In the absence of symptoms, rhabdomyomas require no specific treatment. However, cardiac arrhythmias are unpredictable and may be the cause of sudden cardiac death in some cases. Although treatment is mainly symptomatic, drugs like rapamycin have shown promise in the regression of astrocytomas and angiofibromas. Here, we are reporting two cases of tuberous sclerosis of which one succumbed to arrhythmias and the other to possible sudden cardiac death.
