A 26 yr old asymptomatic woman is found to have arhymias and a systolic murmur associated with Mid-systollic clicks ; which investigation would you use
**Core Concept**
Mitral valve prolapse (MVP) is a condition characterized by the abnormal prolapse of the mitral valve leaflets into the left atrium during systole, often associated with a mid-systolic click and a systolic murmur. This condition is typically diagnosed using a combination of clinical evaluation and imaging studies.
**Why the Correct Answer is Right**
The correct investigation for MVP is echocardiography, specifically a transthoracic echocardiogram (TTE). Echocardiography allows for the visualization of the mitral valve leaflets and the assessment of their motion, helping to confirm the diagnosis of MVP. The TTE also provides information on the left ventricular function, left atrial size, and the presence of any other cardiac abnormalities.
**Why Each Wrong Option is Incorrect**
* **Option A:** Chest X-ray is not a primary investigation for MVP, although it may be used to assess cardiac size and shape.
* **Option B:** Electrocardiogram (ECG) may show nonspecific changes in patients with MVP, but it is not a diagnostic test for the condition.
* **Option C:** Cardiac computed tomography (CT) scan is not typically used for the diagnosis of MVP, although it may be used to assess cardiac structure and function in some cases.
**Clinical Pearl / High-Yield Fact**
MVP is a common condition, affecting approximately 2-3% of the adult population. It is often asymptomatic, but may be associated with mitral regurgitation, atrial fibrillation, and other cardiac complications.
**Correct Answer:** C. Cardiac CT scan
