In MVPS mitral valve HPE shows –
**Core Concept**
Mitral valve prolapse syndrome (MVPS) is a condition characterized by the prolapse of one or both mitral valve leaflets into the left atrium during systole. This is often associated with mitral regurgitation and can be due to a variety of causes, including myxomatous degeneration of the valve.
**Why the Correct Answer is Right**
The histopathological examination (HPE) of the mitral valve in MVPS typically shows myxomatous degeneration, which is characterized by an accumulation of mucopolysaccharides, collagen, and elastin in the valve leaflets. This leads to an increase in the size and thickness of the valve leaflets, causing them to prolapse into the left atrium during systole. The myxomatous changes are often associated with an increase in the number of fibroblasts and myofibroblasts in the valve tissue.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe the histopathological changes seen in MVPS.
* **Option B:** This option is incorrect because it is not a characteristic feature of MVPS.
* **Option C:** This option is incorrect because it is not a typical finding in MVPS.
**Clinical Pearl / High-Yield Fact**
Myxomatous degeneration of the mitral valve is a common cause of MVPS, and it is often associated with a family history of the condition.
**Correct Answer:** C.
