Three-dimensional shape analysis provided additional risk information. This work has been published in JACC: Cardiovascular Imaging (2017, Nov 10. Doi: 10.1016/j.jcmg.2017.08.023).


3D Echocardiographic Quantification of the Left-Heart Chambers Using an Automated Adaptive Analytics Algorithm


Dr. Medvedofsky led this multinational trial to validate a new automated 3D echocardiographic volumetric analysis. The results of this work have been published in European Heart Journal Cardiovascular Imaging (2018;19:47-58).


3D Echocardiographic Quantification of Right Ventricular Volume and Function


Echocardiographic assessment of the right ventricle is challenging because of its complex shape. Dr. Medvedofsky and colleagues have described the acquisition and analysis of a new approach for volumetric assessment in the Journal of the American Society of Echocardiography (2015;28:1222-1231).
