Multiple Choice

The A1/P1 scallop corresponds to which region of the mitral valve leaflet?

Explanation:
The mitral valve leaflets are divided into three scallops from lateral to medial, so the A1/P1 scallop sits at the outer, lateral portion of each leaflet. In other words, this corresponds to the lateral third of the leaflets (near the anterolateral commissure). The central third is the A2/P2 region, and the medial third is the A3/P3 region. This mapping helps precisely localize where a lesion or prolapse involves the valve.
