Tevar Acutely Increases Left Ventricular Work In An Animal Model

Thoracic aortic stent-grafts are thought to decrease aortic compliance and may contribute to hypertension and heart failure post-TEVAR. Left ventricular (LV) biomechanics post-TEVAR have not been quantified. The aim of this study is to use LV pressure-volume (PV) loops to characterize the end systolic pressure (ESP)-volume relationship (ESPVR) and end diastolic pressure (EDP)-volume relationship (EDPVR) in a large animal model.
