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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
