Abstract

: New-generation transcatheter-heart-valves (THV) have significantly improved technical success and procedural safety of transcatheter-aortic-valve-implantation (TAVI) procedures, but incidence of permanent pacemaker implantation (PPI) remains a concern.The study aimed to assess the role of anatomical annulus features in determining peri-procedural conduction disturbances leading to new-PPI following TAVI with the last generation Edwards Sapien balloon-expandable valves (BEV). In the context of a prospective single-center registry, we integrated clinical and procedural predictors of PPI with anatomical data derived from multi-slice-computed-tomography (MSCT). A total of 210 consecutive patients treated with balloon expandable Edwards THV were included in the study from 2015 to 2023. Technical success was achieved in 197 (93.8%) procedures, and 26 patients (12.4%) required new-PPI at 30-day follow-up (median time-to-implantation 3 days). At the univariable logistic-regression analysis, pre-procedural right bundle branch block (RBBB; OR:2.24 [95%CI:1.01-4.97], p=0.047), annulus eccentricity ≥0.25 (OR:5.43 [95%CI:2.21-13.36], p<0.001), calcium volume at annulus of the right coronary cusp (RCC) >48 mm3 (OR:2.60 [95%CI:1.13-5.96], p=0.024) and prosthesis implantation depth greater than membranous septum length (OR:2.17 [95%CI: 1.10-4.28], p=0.026) were associated with new-PPI risk. At multivariable analysis pre-procedural RBBB (OR:2.81 [95%CI:1.01-7.85], p=0.049), annulus eccentricity ≥0.25 (OR:4.14 [95%CI:1.85-9.27], p<0.001), and annulusRCC calcium >48 mm3 (OR:2.89 [95%CI:1.07-7.82], p=0.037) were confirmed as independent predictors of new-PPI. In conclusion, specific anatomical features of the aortic valve annulus might have an additive role in determining the occurrence of conduction disturbances in patients undergoing TAVI with BEV. This suggests the possibility to use the MSCT to improve the prediction of post-TAVI new-PPI risk.
