Three-Dimensional Geometry of Aortic Valve: A new Trial of Visualization With Real-Time Three-Dimensional Echocardiography
J Echocardiogr Vol.5, No.2, 2007 55 Aortic regurgitation (AR) may be congenital or acquired, caused by either abnormalities of the aortic root or the valve itself. Surgical management is recommended in patients with significant AR enough to reduce left ventricular function. Aortic valve (AV) replacement is a common surgical strategy for significant AR, but in some patients who have annuloaortic...

متن کامل[Quantification of aortic valve area using three-dimensional echocardiography].
INTRODUCTION AND OBJECTIVES To determine whether the reproducibility of left ventricular outflow tract (LVOT) area measurement is greater with three-dimensional echocardiographic (3D-echo) planimetry than with conventional 2D-echo. To determine the LVOT circularity index by means of 3D-echo. To determine the usefulness of measuring the LVOT area by 3D-echo for quantifying the severity of valvul...
متن کاملReal-time three-dimensional transthoracic echocardiography.
BACKGROUND Complex anatomy of intra-cardiac structures requires spatial orientation of image in three dimensions for better understanding and enhanced image interpretation. We evaluated the feasibility and efficacy of the emerging 'real-time three-dimensional transthoracic echocardiography' technique for comprehensive assessment of cardiac anatomy, physiology, pathomorphology and pathophysiolog...
متن کاملAnnular sizing using real-time three-dimensional intracardiac echocardiography-guided trans-catheter aortic valve replacement
OBJECTIVE Transcatheter aortic valve replacement (TAVR) has been established as an alternative therapy for patients with severe aortic stenosis who are unfit for the surgical aortic valve replacements. Pre and periprocedural imaging for the TAVR procedure is the key to procedural success. Currently transesophageal echocardiography (TOE), including real-time three-dimensional (RT-3D) imaging TOE...
