Backgrounds
There are limited data on the clinical relevance of transvalvular flow rate (Qmean) at rest (Qrest) and at peak stress (Qstress) during dobutamine stress echocardiography (DSE) in patients with low‐gradient severe aortic stenosis (LG‐SAS).
Methods
We retrospectively analyzed the clinical data of patients with LG‐SAS who underwent DSE. LG‐SAS was defined as an aortic valve (AV) area...
Objective
Dobutamine stress echocardiography (DSE) is not always feasible in patients with low‐gradient severe aortic stenosis (LG‐SAS), and there are limited data available on the resting echocardiographic predictors for true‐severe aortic stenosis (TSAS). This study investigated resting echocardiographic predictors for TSAS.
Methods
Clinical data of 106 LG‐SAS patients who underwent DSE were...
