The heart lesion not found in Congenital Rubella infection is –
**Core Concept**
Congenital Rubella infection is a well-known cause of congenital heart disease, resulting from the rubella virus infecting a fetus during pregnancy. This infection can lead to various heart lesions due to its teratogenic effects on the developing fetus. The most common heart lesions associated with Congenital Rubella infection include patent ductus arteriosus (PDA), pulmonary artery stenosis, and tetralogy of Fallot.
**Why the Correct Answer is Right**
The correct answer is not found in Congenital Rubella infection because it is a rare congenital heart defect that is not typically associated with this viral infection. The pathophysiology of Congenital Rubella infection involves the virus affecting the developing fetus, leading to various heart and other systemic abnormalities. However, Ebstein's anomaly is a rare congenital heart defect characterized by an abnormal formation of the tricuspid valve and right ventricle, which is not commonly seen in Congenital Rubella infection.
**Why Each Wrong Option is Incorrect**
* **Option A:** is incorrect because patent ductus arteriosus (PDA) is one of the most common heart lesions associated with Congenital Rubella infection.
* **Option B:** is incorrect because pulmonary artery stenosis is also commonly seen in Congenital Rubella infection.
* **Option D:** is incorrect because tetralogy of Fallot is another well-known heart lesion associated with Congenital Rubella infection.
**Clinical Pearl / High-Yield Fact**
It is essential to remember that Congenital Rubella infection can lead to a wide range of congenital abnormalities, including heart lesions, cataracts, hearing loss, and intellectual disability. A thorough history and physical examination, including a review of prenatal exposure to rubella, are crucial in identifying affected individuals.
**Correct Answer:** C.
