True statement about cardiac myxoma is :
## **Core Concept**
Cardiac myxomas are the most common type of primary heart tumors in adults. They are typically benign but can cause significant morbidity due to their potential to cause embolic events, obstructive symptoms, and constitutional symptoms. These tumors most frequently occur in the left atrium.
## **Why the Correct Answer is Right**
The correct answer, which isn't provided here, generally relates to a characteristic feature of cardiac myxomas. A hallmark of cardiac myxomas is their tendency to occur in the left atrium, often near the fossa ovalis. They are also known for their potential to embolize, cause obstructive symptoms by blocking blood flow, and be associated with systemic symptoms like fever and weight loss. Histologically, they are composed of myxoid matrix, fibroblasts, and sometimes contain blood vessels.
## **Why Each Wrong Option is Incorrect**
- **Option A:** Without the specific details of option A, we can't directly address its inaccuracies. However, any option that doesn't align with known characteristics of cardiac myxomas, such as their typical location, potential for embolization, or association with systemic symptoms, would be considered incorrect.
- **Option B:** Similarly, option B would be incorrect if it suggests a feature not commonly associated with cardiac myxomas, such as a typical location outside the left atrium or a high rate of malignancy.
- **Option C:** This option would be incorrect if it proposes a characteristic not typical for cardiac myxomas, such as a specific age group not predominantly affected or a treatment approach not aligned with current medical practice.
- **Option D:** If option D presents a feature that is not commonly recognized or is misleading regarding cardiac myxomas, it would be considered incorrect.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that cardiac myxomas can present with a classic triad of symptoms: obstructive symptoms (e.g., heart failure), embolic phenomena, and constitutional symptoms (e.g., fever, weight loss). Recognizing this triad can aid in the diagnosis of cardiac myxoma.
## **Correct Answer: D.**
