The health care provider suggests surgery be performed for ventricular septal defect to prevent what complication?
a. Pulmonary hypertension
b. Right-to-left shunt of blood
c. Pulmonary embolism
d. Left ventricular hypertrophy
ANS: A
Congenital heart defects with a large left-to-right shunt (e.g., in ventricular septal defect, patent ductus arteriosus, or complete AV canal), which cause increased pulmonary blood flow, may result in pulmonary hypertension. If these defects are not repaired early, the high pulmonary flow will cause changes in the pulmonary artery vessels, and the vessels will lose their elasticity. The blood does not shunt right to left, a pulmonary embolism is not a complication of ventricular septal defect, and the left ventricle does not hypertrophy.
