Key result
Real-time three-dimensional echocardiography revealed that mitral valve annular area correlated strongly with body surface area (r=0.78), while age correlated negatively with inter-papillary angle (r=-0.52).
Cross-Sectional (n=120)
Effect estimate: r=0.78
Real-time 3D echocardiography demonstrates that normal mitral valve and papillary apparatus parameters vary widely and are dependent on body surface area and age, highlighting the need for indexed reference values.

Establishes RT3DE mitral reference values across ages and BSA; leaves open standardization before routine clinical use.
Sonne et al. (2008) conducted a cross-sectional in Normal left ventricular function (n=120). Age and body surface area was evaluated on Correlation of mitral valve annular, tenting, and papillary muscle parameters with age and body surface area (r=0.78). Real-time three-dimensional echocardiography revealed that mitral valve annular area correlated strongly with body surface area (r=0.78), while age correlated negatively with inter-papillary angle (r=-0.52).
