Which view is commonly used to assess MVP?

• A. PSAX
• B. AP4-chamber
• C. PLAX
• D. Subcostal

Answer: (C)

The main idea is that MVP is best assessed in a view that shows the mitral leaflets in their long-axis relationship to the left atrium, so prolapse can be seen as the leaflets billowing or moving into the LA during systole. The parasternal long-axis view does this clearly: it displays both leaflets and their motion through the annulus toward the left atrium, allowing you to recognize prolapse and gauge its extent, along with associated regurgitation using color Doppler. Other views can provide useful information about overall valve function, but they’re not as reliable for visualizing the prolapsing leaflet motion. Subcostal windows are more limited for detailed leaflet visualization, and the apical four-chamber view can show MR and chamber size but may not depict the prolapse as clearly. Parasternal short-axis can show the mitral apparatus in cross-section but is more susceptible to foreshortening and isn’t the standard view for identifying MVP.
