Figure 2. Tissue Doppler images showing mitral annular early (e’) and late (a’) diastolic velocities in healthy young and elderly subjects. (A) Septal e’ in young, healthy individual is higher than septal e’ velocity in an elderly healthy individual (B). In comparison, a’ velocity is higher in the older subject. (C) Lateral e’ in young, healthy individual is higher than lateral e’ velocity in an elderly healthy individual (D). In comparison, a’ velocity is higher in the older subject.
