title: Three-dimensional transthoracic echocardiographic assessment of aortic stenosis and regurgitation.
abstract: Color-guided continuous-wave Doppler has important limitations in the assessment of aortic stenosis (AS) and aortic regurgitation (AR). This article outlines the limitations of conventional echocardiographic methods and describes the three-dimensional echocardiographic assessment of AS and AR.
