Imaging the mitral valve segments - a modified approach adapted from reference 47. A basal short axis slice through the mitral commissure is used (top left) to orientate the subsequent image slices for each of the segments. The left atrial appendage is identified by the asterisk (*). Cine sequences are then acquired perpendicular to the mitral commissure for each of the 3 scallops (parallel dashed lines). Systolic frames from the resulting images are shown here (top right and bottom images). In this patient, there is isolated prolapse of the posterior leaflet P2 segment (bottom right, black arrow), but other segments have normal coaption (top right and bottom left).
