Key result
3D matrix transesophageal echocardiography demonstrated reciprocal changes in mitral and aortic annulus areas, with the angle between annuli decreasing from 136±13 degrees at end-diastole to 129±11 degrees in systole.

Supports 3D TEE quantification of mitral-aortic coupling in normal valves; leaves open effects on surgical planning or prosthesis design.
Observational (n=24)
Does 3D matrix transesophageal echocardiography allow for quantitative assessment of mitral and aortic valve dynamics and coupling in patients with normal valves?
3D matrix transesophageal echocardiography allows for quantitative assessment of mitral-aortic coupling in the beating human heart, which may impact evaluation for valvular surgery and prosthesis design.
Veronesi et al. (2008) conducted an observational in normal valves (n=24). 3D matrix transesophageal echocardiography was evaluated on changes in mitral and aortic valve morphology. 3D matrix transesophageal echocardiography demonstrated reciprocal changes in mitral and aortic annulus areas, with the angle between annuli decreasing from 136±13 degrees at end-diastole to 129±11 degrees in systole.
