Question

A two-month-old is showing signs and symptoms of heart failure. An echocardiogram is ordered. The test shows the infant has a ventricular septal defect (VSD). Which statement below best describes the blood flow in the heart due to this congenital heart defect

Answer 1

Answer:

A VSD allows oxygen-rich (red) blood to pass abnormally from the left ventricle through the opening in the septum.

Explanation:

The septal wall prevents the mixing of blood between the two ventricles of the heart. A VSD allows oxygen-rich (red) blood to pass abnormally from the left ventricle through the opening in the septum. Then it mixes with oxygen-poor (blue) blood in the right ventricle.
