Popis: OBJECTIVES 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. BACKGROUND Post/preprocedural ARI increases accuracy of residual AR assessment by considering hemodynamic status prior to TAVR. METHODS 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
