Atrial Septal Defect

The heart can dilate, the muscle can become weak, and the pressures in the pulmonary arteries can increase (pulmonary hypertension) due to the increase in blood flow. [heartpoint.com]

If a large atrial septal defect goes untreated, increased blood flow to your lungs increases the blood pressure in the lung arteries (pulmonary hypertension). [mayoclinic.org]

Over time, too much blood flow to the lungs can increase the pressure in the pulmonary arteries (blood vessels leading from the heart to the lungs). [saintlukeskc.org]

Unlike systemic high blood pressure, this condition affects only the arteries in your lungs. [mayoclinic.org]

It begins when the smallest arteries and capillaries are compressed by scar tissue, causing increased resistance to blood flow in your lungs. [mayoclinic.org]

Neonatal Respiratory Distress Syndrome

Increased alveolar oxygen tension further expands the precapillary vascular space through dilatation of arteries and arterioles. [histopathology-india.net]

The ductus arteriosus connects pulmonary arteries to the aorta. If it remains open, it can strain the heart and increase blood pressure in the lung arteries. [nhlbi.nih.gov]
