A composite three‐dimensional (3D) echographic left ventricular (LV) reconstruction to measure LV volumes was evaluated in 26 children. Four apical views, to minimize assumptions about LV shape, were used to obtain a “wire‐cage” model of the LV in 3D. Numerical integration was used to make estimates of both end‐diastolic and end‐systolic volumes. Volume estimates obtained with echographic techniques and those obtained with the angiographic biplane method were compared. The echographic volume estimates were systematically smaller ( p < 0.005), and a consistent trend, though not significant, was observed indicating that this systematic error is less for the 3D method. One‐way analysis of variance confirmed significant global geometric fluctuations. Hence, 3D reconstruction can be performed in a clinical setting, and the enhanced graphic representation of global LV geometry may contribute to improved patient management.
