• W2894291281 abstract "We aimed to investigate the value of post/preprocedural aortic regurgitation index (ARI) ratio as a marker for more-than-mild aortic regurgitation (AR) after transcatheter aortic valve replacement (TAVR) and as an indication of the need for corrective measures, provided that the implantation depth was acceptable.Post/preprocedural ARI increases accuracy of residual AR assessment by considering hemodynamic status prior to TAVR.ARI ratio was calculated in 70 patients undergoing TAVR. ARI ratios were defined as post/preprocedural ARI (ARI ratio 1), and as postcorrective measure/preprocedural ARI (ARI ratio 2). Intraprocedurally, corrective measures use was decided based on angiographically assessed AR severity. The relationship of such decisions to ARI ratios based on a recently proposed threshold (ARI ratio < 0.6) was evaluated. ARI ratios in corrected versus noncorrected patients and precorrection versus postcorrection values were assessed.Overall, mean (±SD) ARI ratio 1 (n = 70) was 0.81 (±0.36). Corrective measures were used in 22 patients (31.4%). Mean ARI ratio 1 in such patients was 0.55 (±0.25) versus 0.93 (±0.34) in the 48 noncorrected patients (P < 0.0001). Mean ARI ratio 1 in 21 patients requiring postdilation was 0.56 (±0.25), which was below the previously suggested 0.6 threshold. After postdilation, ARI ratio 2 increased to 0.85 (±0.16) (P < 0.0001), with all patients showing an ARI ratio 2 ≥ 0.6.ARI ratio is closely related to intraprocedural decisions to perform corrective measures based on angiography. Routine use of intraprocedural ARI ratio could be useful as a complementary quantitative marker for residual AR and for the need for corrective measures." @default.
