文摘

Transcatheter aortic valve replacements lower mortality in patients not suitable for surgical valve replacement compared to conservative treatment. Transcatheter valve-in-valve implants have been shown to be feasible in failed bioprostheses in aortic, mitral, pulmonary and tricuspid positions. We report the first Australasian experience of a transapical mitral valve-in-valve placement with an Edwards Sapien^? transcatheter valve for a failed mitral bioprosthesis, focussing on the technical aspects of this novel procedure. Whilst the evidence for this niche indication is limited currently to case reports and case series, further evaluation of its long term outcomes may justify its use in this particularly high risk group of re-do sternotomy patients.
