Key result
Mitral annular excursion volume calculated via 4-D TEE accounted for 19 ± 3% of total left ventricular stroke volume and correlated strongly with it (r=0.73; P<0.05).
Why the study?

What is the contribution of mitral annular excursion and shape variation to total left ventricular volume change in healthy subjects?
Effect estimate: r = 0.73
p-value: p=< 0.05
Mitral annular excursion accounts for approximately 19% of total left ventricular stroke volume, demonstrating a significant atriogenic and sphincter-like contribution to ventricular filling and emptying.

Supports atriogenic LV contribution in health; leaves open disease relevance and requires prospective validation.
Carlhäll et al. (2004) conducted an observational in Healthy (n=9). 4-D transesophageal echocardiography (TEE) was evaluated on Contribution of annular excursion volume (AEV) to total LV stroke volume (r = 0.73, p=< 0.05). Mitral annular excursion volume calculated via 4-D TEE accounted for 19 ± 3% of total left ventricular stroke volume and correlated strongly with it (r=0.73; P<0.05).
