What would be the utility of calcium scoring for the evaluation of low-flow low-gradient aortic stenosis, and what cut-off values typically fall within the severe range?

Echo findings can be equivocal in as many as 40% of patients. Multiple studies have demonstrated a good correlation of calcium score and the severity of AS. A calcium score of 1300 in females and 2000 in men are defined cutoffs. In low flow low gradient AS with diminished EF a dobutamine echo should...
