Prenatal Detection and Neonatal Management of Tuberous Sclerosis Complex Compounded by Symptomatic Cardiac Arrhythmia.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant syndrome affecting multiple organ systems through the development of benign hamartomas. We present a newborn female patient suspected antenatally of having TSC based on fetal echocardiography, which suggested cardiac rhabdomyomas; these findings were confirmed postnatally. The patient was managed with regular multidisciplinary follow-up and treated according to her presenting manifestations, including neonatal cardiac arrhythmias. This case highlights the importance of early genetic confirmation and proactive management of neonatal complications.
