Is trans-catheter implantation of an aortic valve within a failed mitral annuloplasty ring feasible?
This case report demonstrates the first-in-man feasibility of trans-catheter valve-in-ring implantation for treating failed mitral annuloplasty.
Transcatheter mitral valve-in-ring appears feasible in select cases; leaves open durability, safety, and generalizability for prospective evaluation.
The trans-catheter valve-in-valve concept has become a feasible therapeutic option for patients with failing degenerated bioprosthesis, who are deemed inoperable. However, little is known about the feasibility of this technique in failed valve annuloplasty. We report the first-in-man implantation of a trans-catheter aortic valve within a mitral annuloplasty ring. Through a trans-apical trans-catheter approach, a 26-mm Sapien-Edwards valve was successfully implanted in a 72-year-old man with ischemic heart failure and failed mitral-valve annuloplasty. The present case report provides a critical appraisal of the procedural technique.
