117
Q

What is patent ductus arteriosis?

A

The duct that runs from the pulmonary artery to the aorta doesn’t close after birth
-after birth, some of the blood gets shunted back into the pulmonary trunk, causing enlargement of the pulmonary arteries, lungs, left atrium, and left ventricle

118
Q

What is an atrial septal defect?

A

The foramen ovale doesn’t close off within the first year of life as it should

  • blood from the high pressure left atrium is shunted to the lower pressure right atrium after birth which increases the workload of the right ventricle and leads to increased flow to the lungs
  • increased lung marking and enlarged pulmonary outflow tract
119
Q

What is a ventricular septal defect?

A

Abnormal opening between the right and left ventricles

  • increased flood flow to and from the lungs, increased workload for the left atrium and ventricle
  • enlargement of the pulmonary trunk, left atrium and ventricle, as well as increased pulmonary markings
120
