Flow versus resistance: hemodynamic phenotyping of pulmonary hypertension in infants with shunts and concurrent lung disease
Neonatal pulmonary hypertension (PH) can be categorized into three distinct physiologies: resistance-driven precapillary pulmonary arterial hypertension (PAH), flow-driven precapillary PH, and postcapillary PH. We present eight patients, divided into three groups: premature infants with BPD, infants with chronic respir...
