lnfants of diabetic mothers are likely to have the following cardiac anomaly
**Core Concept**
The question is testing the knowledge of congenital cardiac anomalies associated with infants of diabetic mothers, specifically focusing on the teratogenic effects of maternal diabetes on fetal heart development. Maternal diabetes is a known risk factor for various congenital anomalies due to the **hyperglycemic environment** it creates during embryogenesis.
**Why the Correct Answer is Right**
Although the specific correct answer is not provided, one of the most common cardiac anomalies associated with infants of diabetic mothers is **hypoplastic left heart syndrome**. However, another significant and commonly referenced anomaly in this context is **transposition of the great arteries**. The exact mechanism involves the teratogenic effects of hyperglycemia on the developing fetus, particularly during the critical periods of organogenesis.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, it's challenging to provide a precise reason for its incorrectness.
**Option B:** Similarly, without knowing what option B entails, it's difficult to explain why it's incorrect.
**Option C:** And option C, lacking specific information, cannot be directly addressed as to why it is not the correct answer.
**Option D:** The same applies to option D, as the content of this option is not provided.
**Clinical Pearl / High-Yield Fact**
Infants of diabetic mothers are at an increased risk for various congenital anomalies, with cardiac anomalies being among the most common. It's crucial for early prenatal screening in diabetic mothers to identify potential issues early on.
**Correct Answer:** Correct Answer: D. Transposition of the great arteries.
