Key result
Valve-in-valve TAVI prevents further migration into the LV by jailing the initial prosthetic valve.
Why the study?
Accurate sizing of the aortic annulus prior to TAVI is critical to prevent acute prosthetic valve migration, which can complicate the procedure.
Valve-in-valve implantation can serve as an emergency rescue technique to prevent acute prosthetic valve migration into the left ventricle during TAVI.
Emphasizes precise annular sizing to avert TAVI migration; case report leaves open generalizability of jailing technique.
This case demonstrates the importance of accurate sizing of aortic annulus prior to TAVI. There was migration of first valve after deployment and therefore to prevent further migration to the left ventricle, a new TAVI valve was deployed jailing the first valve.

Showkathali et al. (2015) studied this question. Valve-in-valve implantation during TAVI successfully prevented further migration of an initially deployed prosthetic valve into the left ventricle by jailing the first valve.
