A neonate is diagnosed with congenital rubella syndrome. On echocardiography, which cardiac defect is most classically associated with this condition?

• A Patent ductus arteriosus ✓
• B Tetralogy of Fallot
• C Ventricular septal defect
• D Transposition of the great arteries

Explanation

The classic triad of congenital rubella syndrome consists of patent ductus arteriosus, cataracts, and sensorineural hearing loss. While pulmonary stenosis and ventricular septal defects can also occur, PDA is the most classically associated cardiac defect. Tetralogy of Fallot and transposition of the great arteries are not typically linked to congenital rubella infection, making them incorrect choices.
