The severity of Aortic stenosis is underestimated when evaluated by doppler mean gradients in patients with Atrial Fibrillation compared to Sinus Rhythm, as a result of low forward flow. A flow independent computed tomographic aortic valve calcium scores at the time of transcatheter aortic valve replacement in 663 patients between the years 2016-2020 were used to evaluate the degree of aortic valve stenosis. Significantly higher than expected calcium scores in the atrial fibrillation group were suggestive of more severe stenosis at the time of referral for valve replacement.
