Key result
Right parasternal view optimizes aortic stenosis severity assessment during dobutamine stress echocardiography in low-flow states.
Why the study?
Accurate hemodynamic evaluation of aortic stenosis severity during dobutamine stress echocardiography in low-flow, low-gradient AS can be challenging.
Does the right parasternal view improve hemodynamic evaluation of AS severity during dobutamine stress echocardiography in a patient with low-flow, low-gradient AS?
Does the right parasternal view improve hemodynamic evaluation of AS severity during dobutamine stress echocardiography in a patient with low-flow, low-gradient AS?
The right parasternal view can provide optimal hemodynamic evaluation of AS severity during dobutamine stress echocardiography in patients with low-flow, low-gradient aortic stenosis.
Right parasternal view may improve AS assessment during DSE in select low-flow cases; hypothesis-generating and requires prospective validation.
We present the case of a 77-years-old man with aortic valve stenosis (AS) and reduced left ventricular ejection fraction, in whom right parasternal view provided the best hemodynamic evaluation of AS severity during dobutamine stress echocardiography.
