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\u2009&lt;\u20090.6) was evaluated. ARI ratios in corrected versus noncorrected patients and precorrection versus postcorrection values were assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, mean (\u00b1SD) ARI ratio 1 (<jats:italic>n<\/jats:italic> =\u200970) was 0.81 (\u00b10.36). Corrective measures were used in 22 patients (31.4%). Mean ARI ratio 1 in such patients was 0.55 (\u00b10.25) versus 0.93 (\u00b10.34) in the 48 noncorrected patients (<jats:italic>P<\/jats:italic> &lt;\u20090.0001). Mean ARI ratio 1 in 21 patients requiring postdilation was 0.56 (\u00b10.25), which was below the previously suggested 0.6 threshold. After postdilation, ARI ratio 2 increased to 0.85 (\u00b10.16) (<jats:italic>P<\/jats:italic> &lt;\u20090.0001), with all patients showing an ARI ratio 2 \u2265\u20090.6.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>ARI ratio is closely related to intraprocedural decisions to perform corrective measures based on angiography.
