On multivariable analysis, the independent predictors of AR\u22652+ were: larger annulus diameter (OR 1.78, 95%CI 1.25\u20132.55; <jats:italic>P<\/jats:italic> = 0.002), low implantation (OR 3.67, 95%CI 1.01\u201313.35, <jats:italic>P<\/jats:italic> = 0.05), and peripheral vascular disease (OR 3.54, 95%CI 1.19\u201310.56, <jats:italic>P<\/jats:italic> = 0.02). Post\u2010CoreValve implantation, AR \u2265 2 was seen in 40.5% (32\/79). Twenty\u2010one patients underwent postdilatation with improvement in AR grade in the majority (17\/21). Of the four patients who did not respond to postdilatation, two underwent valve\u2010in\u2010valve implantation. In one patient, the valve was pulled more proximally by the snare technique. The remaining 10 patients were treated conservatively. <jats:bold><jats:styled-content>Conclusion<\/jats:styled-content>:<\/jats:bold> The appropriate strategy for treating patients with AR\u22652+ depends on the causes and severity of AR post\u2010TAVI. This study suggests that we should carefully select the size of CoreValve prosthesis to prevent prosthesis mismatch, especially when implanted in larger annulus sizes. For valves implanted in the appropriate position, postdilatation appears effective in reducing the degree of AR. \u00a9 2011 Wiley\u2010Liss,
