Restrictive cardiomyopathy (RCM) is a rare but serious heart condition characterized by the stiffening of the ventricles, which restricts the heart's ability to fill with blood during the diastolic phase. This leads to impaired ventricular filling, increased diastolic pressure, and subsequently, congestive heart failure. In the context of neonatal disorders, RCM is particularly challenging due to the limited treatment options and the delicate health of newborns.
