Persistent pulmonary hypertension of the newborn, also known as persistent fetal circulation, is a condition caused by a failure of the systemic and pulmonary circulation to convert from the antenatal circulation pattern to the normal postnatal pattern. Affected infants experience a high mean arterial pulmonary artery pressure and a high afterload at the right ventricle, meaning the heart works against higher pressures, which makes it more difficult for the heart to pump blood.

Persistent fetal circulation is a condition caused by a failure in the systemic circulation and pulmonary circulation to convert from the antenatal circulation pattern to the "normal" pattern.
Lead section, body-system statement (cardiovascular)
Infants experience a high mean arterial pulmonary artery pressure and a high afterload at the right ventricle.
Lead section, body-system statement (reproductive)
In a fetus, there is high pulmonary vascular resistance (PVR) and low pulmonary blood flow as the fetus does not use the lungs for oxygen transfer, but instead relies on the placenta for oxygen.
