After teaching a class about the hemodynamic characteristics of congenital heart disease, the instructor determines that the teaching has been successful when the class identifies which defect as an example of a disorder involving increased pulmonary blood flow?

Transposition of The Great Arteries

Coarctation of the Aorta

Patent Ductus Arteriosus

Tetralogy of Fallot

Answer and Explanation

The Correct Answer is C

A. Transposition of The Great Arteries involves abnormal positioning of the arteries, leading to systemic and pulmonary circulations being disconnected, rather than increased pulmonary blood flow.

B. Coarctation of the Aorta is a narrowing of the aorta that can cause increased pressure in the upper extremities but does not involve increased pulmonary blood flow.

C. Patent Ductus Arteriosus (PDA) is a condition where the ductus arteriosus fails to close, causing increased blood flow to the lungs, leading to pulmonary overcirculation.

D. Tetralogy of Fallot leads to decreased pulmonary blood flow due to pulmonary stenosis and right ventricular hypertrophy.

Correct Answer is B

Explanation

A. Turner syndrome is a chromosomal disorder affecting females and does not typically coincide with VSD.

B. Trisomy 18 (also called Edwards syndrome) is a chromosomal disorder that often presents with congenital heart defects, including VSD.

C. Spina bifida is a neural tube defect and is not directly related to VSD.

D. Trisomy 21 (Down syndrome) may have congenital heart defects but is not specifically associated with VSD as commonly as trisomy 18.

A. Aortic stenosis (AS) B. Transposition of the Great Vessels (Arteries) C. Coarctation of the Aorta (COA) D. Tetralogy of Fallot (TOF)

Correct Answer is C

Explanation

A. Aortic stenosis (AS) typically causes a difference in blood flow across the aortic valve but does not usually require assessment of upper and lower extremity blood pressures.

B. Transposition of the Great Vessels (Arteries) results in cyanosis and abnormal circulatory flow but does not require upper and lower extremity blood pressure monitoring.

C. Coarctation of the Aorta (COA) is characterized by narrowing of the aorta, often resulting in higher blood pressure in the upper extremities compared to the lower extremities. Measuring both helps identify this condition.

D. Tetralogy of Fallot (TOF) involves right ventricular outflow obstruction, VSD, overriding aorta, and right ventricular hypertrophy, but upper and lower extremity blood pressures are not typically used for diagnosis.
