The IVS is a pivotal region of the electrical conduction system of the heart where the atrioventricular conduction axis is located.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>Included were 78 patients with severe aortic stenosis who underwent CT imaging prior to TAVR. The thickness of muscular IVS was measured in the coronal view, in systolic phases, at 1, 2, 5, and 10\u2005mm below the membranous septum (MS). The primary endpoint was a composite of conduction disturbance following TAVR. Conduction disturbances occurred in 24 out of 78 patients (30.8%). Those with conduction disturbances were significantly more likely to have a thinner IVS than those without conduction disturbances at every measured IVS level (2.98 \u00b1 0.52\u2005mm vs. 3.38 \u00b1 0.52\u2005mm, 4.10 \u00b1 1.02\u2005mm vs. 4.65 \u00b1 0.78\u2005mm, 6.11 \u00b1 1.12\u2005mm vs. 6.88 \u00b1 1.03\u2005mm, and 9.72 \u00b1 1.95\u2005mm vs. 10.70 \u00b1 1.55\u2005mm for 1, 2, 5 and 10\u2005mm below MS, respectively, P &amp;lt; 0.05 for all). Multivariable logistic regression analysis showed that pre-procedural IVS thickness (&amp;lt;4\u2005mm at 2\u2005mm below the MS) was a significant independent predictor of post-procedural conduction disturbance (adjOR 7.387, 95% CI: 2.003\u201327.244, P = 0.003).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Pre-procedural CT assessment of basal IVS thickness is a novel predictive marker for the risk of conduction disturbances following TAVR.
