Huge cardiac rhabdomyoma in a neonate: A surgical challenge.

Cardiac rhabdomyomas are the most common primary cardiac tumors observed in neonates and children, which have been frequently associated with the tuberous sclerosis complex. These benign tumors usually have a natural history of regression but can sometimes cause significant clinical issues by obstructing blood flow and arrhythmias. We present an unusual case of a neonate who presented with a large cardiac rhabdomyoma with obstruction to the right ventricular inflow and outflow. The tumor necessitated an urgent surgery, which proved to be technically challenging.
