SEVERITY OF AORTIC REGURGITATION ASSESSED BY AREA OF VENA CONTRACTA- A CLINICAL COLOR DOPPLER IMAGING STUDY

Quantitation of aortic regurgitation (AR) using echocardiography including the width of vena contracta (VC-W) is challenging. Three-dimensional (3D) echocardiography can directly measure the size of vena contracta area of AR jet regardless of rheological characteristics. We intended to assess the
