Which combination best describes MVP leaflets?

Which combination best describes MVP leaflets?

• A. Redundant; greater than 5 mm
• B. Redundant; less than 3 mm
• C. Thickened; greater than 5 mm
• D. Stiff; 3-5 mm

Answer: (A)

MVP leaflets are described as redundant because there is excess leaflet tissue that allows them to billow or prolapse into the left atrium during systole. The key imaging descriptor is how far the leaflet edge moves into the atrium; a larger prolapse height reflects more pronounced displacement. Among the options, describing the leaflets as redundant with a prolapse greater than 5 mm best matches this concept: the tissue is extra (redundant) and the displacement into the atrium is substantial, which aligns with how MVP is characterized on ultrasound. The other choices either emphasize thickness or stiffness, or pair redundancy with a smaller or unrelated measurement, which don’t capture the typical combination seen in MVP leaflets.
