Why the study?
Does transesophageal three-dimensional echocardiography allow for the quantitative assessment of normal and stenotic aortic valves?
Does transesophageal three-dimensional echocardiography allow for the quantitative assessment of normal and stenotic aortic valves?
Transesophageal three-dimensional echocardiography is a feasible technique for assessing aortic valve morphology and orifice area in normal and stenotic valves.
May aid aortic valve planimetry in select cases; leaves open validation and outcome impact before wider adoption.
The present study demonstrates the feasibility of transesophageal three-dimensional reconstruction of normal, sclerotic, and stenotic aortic valves using a computed tomographic ultrasound system. The study also shows the potential clinical usefulness of this technique in delineating aortic valve morphology (extent and severity of valve thickening and calcification and size and number of cusps) and assessing aortic orifice areas by direct planimetry of the three-dimensional images.
