Background The assessment of hemodynamics in patients supported with left ventricular
assist devices (LVADs) is often challenging. Physical examination maneuvers correlate
poorly with true hemodynamics. We assessed the value of novel transthoracic
echocardiography (TTE)–derived variables to reliably predict hemodynamics in patients
supported with LVAD. Methods and Results A total of 102 Doppler-TTE images of the LVAD
outflow cannula were obtained during simultaneous invasive right heart catheterization …

Purpose Hemodynamics assessment in patients supported with left ventricular assist
devices (LVAD) is often challenging. This study aimed to developed echocardiographic
(TTE) derived variables that can reliably predict hemodynamics in LVAD patients. Methods
TTE images of the LVAD outflow graft were obtained during simultaneous right heart
catheterization. Properties of the Doppler signals though the outflow graft were measured
including the systolic slope (SS), diastolic slope (DS) and velocity time integral (VTI) …
