Stahli BE, Abouelnour A, Nguyen TD et al (2014) Impact of three-dimensional imaging and pressure recovery on echocardiographic evaluation of severe aortic stenosis: a pilot study. Echocardiography 31:1006-1016While the previous studies assessed quantification of aortic valve calcification, prognostic value of aortic regurgitation after TAVI, impact of three-dimensional imaging and pressure recovery on echocardiographic evaluation of severe aortic stenosis and value of previously reported CT signs and measurements as a predictor of pulmonary hypertension and mortality in severe aortic stenosis, this work focused on whether IVC measurements are correlated with central venous pressure and the predictive value of IVC measurements on one-year mortality after TAVI. Thus, this work is substantially different from the previous reports. Additionally, in contrast to the aforementioned studies the present study is the only one including all patients undergoing TAVI between 01/2011 and 12/2014 at our institution.
