Valvular function parameters were compared at baseline, post procedure, and 30 days. Among 172 CV TAVR patients, 11 required a second device (6%) due to significant residual AR. The main differences between the groups were higher rates of low ejection fraction in patients with 2 CV implanted and higher annular diameter (27 [29\u201325] vs. 25 [26\u201324] mm, <jats:italic>P<\/jats:italic>\u2009=\u20090.03), requiring a larger device. Although two patients in the two CV group had high initial implantation, low implantation was similar between the groups. A second CV achieved adequate reduction in residual AR in six patients (55%), while an additional four patients had moderate residual AR. Only one remained with moderate to severe AR after 30 days follow\u2010up. There were no cases of peri\u2010procedural stroke or mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Second implantation of self\u2010expanding valve can
