The SphygmoCor XCEL device estimates central blood pressure (BP) measurement with its easy\u2010to\u2010use, operator\u2010independent procedure. However, this device has not been properly validated against invasive measurement in patients with severe AS. We evaluated the relationship between cuff\u2010brachial BP, transfer function\u2010estimated and invasively measured central aortic pressure in patients with severe AS before and after transcatheter aortic valve replacement (TAVR). Agreement between techniques was analyzed and, according to the ARTERY Society recommendations, the minimum acceptable error was a mean difference\u00a0\u00b1\u00a0SD \u22645\u00a0\u00b1\u00a0\u22648\u00a0mm Hg. A total of 94 patients with AS undergoing TAVR had simultaneous non\u2010invasive and invasive measurements of central BP before and after the procedure. Before TAVR central systolic BP was in average slightly underestimated, though with wide variability, when using the default calibration of brachial\u2010cuff SBP (mean difference\u00a0\u00b1\u00a0SD, \u22123\u00a0\u00b1\u00a015\u00a0mm Hg), and after TAVR the degree of underestimation increased (mean difference\u00a0\u00b1\u00a0SD, \u22129\u00a0\u00b1\u00a013\u00a0mm Hg). The agreement tended to improve for those patients with low aortic gradient stenosis compared to those with high gradient at baseline (mean difference\u00a0\u00b1\u00a0SD, \u22122\u00a0\u00b1\u00a011\u00a0mm Hg vs. \u22124\u00a0\u00b1\u00a017, respectively, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.3). The cuff\u2010brachial systolic BP yielded numerically lower degree of agreement and weaker correlation with invasive measurements than SphygmoCor XCEL. In patients with severe AS the SphygmoCor XCEL cuff device, despite showing strong correlation, does not meet the ARTERY Society accuracy criteria for non\u2010invasive measurement of central SBP.<\/jats:p>","DOI":"10.1111\/jch.14245","type":"journal-article","created":{"date-parts":[[2021,5,4]],"date-time":"2021-05-04T07:18:09Z","timestamp":1620112689000},"page":"1165-1175","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Validation
