Key result
Echocardiographic intervals of the mitral valve, specifically the second heart sound to E-wave peak and E-F intervals, were significantly longer in older age groups compared to younger subjects.
Why the study?
Do echocardiographic wave intervals of the mitral valve differ across age groups in normal subjects?

Clinicians should account for age in mitral valve interval interpretation to avoid misdiagnosis; leaves open need for prospective normative validation.

Do echocardiographic wave intervals of the mitral valve differ across age groups in normal subjects?
Echocardiographic intervals of the mitral valve naturally lengthen with age in normal subjects, highlighting the need to account for age to avoid misdiagnosing normal variations as disease.
Luisada et al. (1975) conducted a cross-sectional in Normal subjects without evidence of heart disease (n=71). Echocardiogram of the mitral valve (A mode) vs. Comparison across age groups was evaluated on Intervals between various echocardiographic waves (second heart sound to peak of E-wave, E-F intervals). Echocardiographic intervals of the mitral valve, specifically the second heart sound to E-wave peak and E-F intervals, were significantly longer in older age groups compared to younger subjects.
