20 cze 2016 · The growing availability of 3D echocardiography (3DE) over the last decade has allowed its applications to expand from establishing reference values for chamber size and elucidating ventricular mechanics, to assessing valvular disease severity and playing pivotal roles in interventional procedures.
Three-dimensional (3D) echocardiography allows the real-time acquisition of volumes containing entire cardiac structures. The analysis of 3D volumes does not require any assumptions as to the shape of structures.
Comment: A comprehensive tutorial to guide the echocardiographer to understand the controls and function of 3D echo systems, to learn how to acquire 3D data-sets with the different 3D image acquisition modes and to start acquiring images with a 3D acquisition protocol.
Direct measurement without geometrical assumptions about cavity shape and hypertrophy distribution. More accurate that the linear or the 2D measurements. Higher inter-measurement and test/retest reproducibility. Better discriminates small.
The 3-dimensional (3D) echocardiography–derived virtual reality images of a patient with a bioprosthetic mitral valve (MV) who subsequently underwent transcatheter mitral valve replacement (TMVR).
Three-dimensional echocardiography, through the en face view, allows all three leaflets to be evaluated concurrently, as well as assessment of the RVoutflow tract and main pulmonary ar-tery. This has improved quantitative assessment of pulmonary regur-gitation and stenosis.
