Warrants vigilant post-procedural imaging after Sapien XT mitral ViV; leaves open optimal device selection and anchoring strategies.
We report two cases of delayed migration of the Sapien XT device after a successful mitral valve-in-valve (VIV) implantation. The procedure was performed through a transapical approach. Echocardiography was used to choose the size of the Sapien XT device. Although the immediate results were satisfactory both the cases presented with severe regurgitation (1 week and 3 months). Investigations revealed atrial migration of the Sapien device in both the cases, which was confirmed at the time of reoperation. We discuss possible mechanisms, which could have resulted in the delayed migration and highlight the difference between VIV procedures in mitral position versus other positions.

Bapat et al. (2013) conducted a case report in Mitral valve-in-valve implantation (n=2). Sapien XT device was evaluated on Delayed migration of the device. Transcatheter mitral valve-in-valve implantation using the Sapien XT device resulted in delayed atrial migration and severe regurgitation at 1 week and 3 months in two cases.
