What is the most characteristic cardiovascular defect seen in congenital rubella syndrome?
Show Hint
Rubella heart lesions are PDA and pulmonary artery stenosis.
Updated On: Jun 23, 2026
- Pulmonary artery stenosis
- Coarctation of aorta
- Ankylosing spondylitis
- Rheumatic fever
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Recall the congenital rubella triad: deafness, eye lesions and heart disease. The question targets the heart component.
Step 2: Rubella classically damages the developing great vessels and ductus, producing patent ductus arteriosus and pulmonary artery (pulmonary branch) stenosis. Of the listed choices, only pulmonary artery stenosis matches.
Step 3: Eliminate the rest. Coarctation of the aorta is linked with conditions like Turner syndrome, not rubella. Ankylosing spondylitis is a joint and spine disease and does not belong on a list of congenital cardiac defects. Rheumatic fever is acquired after group A streptococcal throat infection.
Step 4: The single congenital cardiac lesion tied to rubella is clear.
\[\boxed{\text{Pulmonary artery stenosis}}\]
