WebSep 20, 2024 · INTRODUCTION. Persistent pulmonary hypertension of the newborn (PPHN) occurs when pulmonary vascular resistance (PVR) remains abnormally elevated after birth, resulting in right-to-left shunting of blood through fetal circulatory pathways. This in turn leads to severe hypoxemia that may not respond to conventional respiratory support.
WebKey Points. Persistent pulmonary hypertension of the newborn is the persistence of or reversion to pulmonary arteriolar constriction, causing a severe reduction in pulmonary blood flow and right-to-left shunting at the atrial and/or ductal level. Symptoms and signs include tachypnea, retractions, and severe cyanosis or desaturation unresponsive ... WebAs right ventricular volume overload andenlargement ensues, pulmonary pressures rise and theleft ventricular compliance exceeds the right-sidedcompliance, leading to right-to-left shunting. Theeffects of shunts include arrhythmias, endocarditis,right and left ventricular dysfunction, paradoxicalemboli, and pulmonary hypertension. 2 Closure ofthese defects …
