Safety and utility of dobutamine and pressure wire use in the hemodynamic assessment of low flow, low gradient aortic stenosis with reduced left ventricular ejection fraction.

Abstract

BACKGROUND The ACC/AHA guidelines recommend low-dose dobutamine challenge for hemodynamic assessment of the severity of AS in patients with low flow, low gradient aortic stenosis with reduced ejection fraction (EF) (LFLG-AS; stage D2). Inherent pitfalls of echocardiography could result in inaccurate aortic valve areas (AVA), which have downstream prognostic… (More)
