The linear axial area on raphe valves widens slightly near the valve center, and the transapically rectangular to oval central area is bounded by 45 shortened striae. External proximal raphe endings are located in grooves, which gradually widen toward valve center. External distal raphe endings are drop-shaped and do not extend beyond the last stria (
