Low gradient ( Click to show full abstract
Low gradient (<40 mm) aortic valve stenosis (AVA < 1.0 cm2) outcomes with TAVR are worse than when gradients are > 40 mm Hg. Concomitant coronary disease, older age, presence of diabetes, and lower ejection fraction in patients with low gradient aortic valve stenosis account for the poorer outcome after TAVR. Historically, similar results have been seen with surgical AVR.
