摘要: Aortic valve stenosis (AS) severity can be estimated by various modalities. Due to some of the limitations currently available methods, usefulness live three-dimensional transthoracic echocardiography (3D TTE) in assessment AS was explored. Live 3D TTE able visualize aortic orifice all 11 patients studied. correctly 10 whom could evaluated at surgery. These included eight with severe and two moderate AS. Two these had associated hypertrophic cardiomyopathy underwent myectomy time replacement. area measurements correlated well intraoperative transesophageal echocardiographic reconstruction (r=0.85) but not as two-dimensional (r=0.64). also did correlate (r=0.46) number studied smaller (only seven) four undergo authors' institution. Altogether, TTE, subsequently confirmed surgery, were misdiagnosed having echocardiography. Because it is completely noninvasive views three dimensions, a useful complement existing modalities evaluation severity.
