Abstract: Background: The Navitor valve shows excellent valve function and high deliverability. However, valve pop-up during valve implantation remains a concern. Methods and Results: We defined pop-up as an upward valve dislocation ≥3 mm after implantation. Pop-up occurred in 13 (19%) of 67 patients, with 2 (3.0%) patients requiring a second valve. The depth ratio between non- and left-coronary cusp side at the 80% release and aortic valve calcification score were identified as predictors of valve pop-up. Conclusions: Pop-up of the Navitor valve occurred in 19% of patients. Inconsistent valve depth and severe leaflet calcification were predictors of valve pop-up.
