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.
