Correct answer: D — Spontaneous regression in most cases during infancy

Cardiac rhabdomyomas in TSC typically spontaneously regress during infancy and early childhood. Surgery is only needed if they cause significant outflow tract obstruction, arrhythmias, or haemodynamic compromise. Everolimus (mTOR inhibitor) can accelerate tumour regression if clinically needed.
