Pulmonary Hypertension (PH) in neonates is a serious condition characterized by elevated blood pressure in the pulmonary arteries. This disorder can lead to significant morbidity and mortality if not promptly diagnosed and managed. PH in neonates is often associated with conditions such as Persistent Pulmonary Hypertension of the Newborn (PPHN), congenital diaphragmatic hernia, and congenital heart disease.
