Integrated RF and B-mode Deformation Analysis for 4D Stress Echocardiography
December 6, 2023 updated by: Yale University
The specific aim of this clinical trial is to translate the investigators new 4DE (three sptial dimensions pluse time) stress echocardiographic method to patients with coronary artery disease referred for clinically indicated dobutamine stress/rest echo to evaluate the reproducibility of the technique in this clinical setting.
