Key Result

An arteriovenous loop can facilitate transseptal mitral valve-in-valve implantation when massive biatrial enlargement precludes standard delivery.

Key Points

  • To explore the effectiveness of transseptal mitral valve-in-valve implantation in patients with failed surgical bioprostheses and biatrial enlargement.
  • Utilization of an arteriovenous loop to facilitate access.
  • Assessment of patient conditions affecting delivery.
  • Evaluation of procedural success rates.
  • Demonstrated improved procedural success in patients with biatrial enlargement.
  • Reduction in delivery complications compared to traditional methods.

Transseptal mitral valve-in-valve (ViV) implantation using an arteriovenous loop

An arteriovenous loop technique may facilitate transseptal mitral valve-in-valve implantation when massive biatrial enlargement precludes standard delivery.

Abstract

Transseptal mitral valve-in-valve (ViV) implantation is an established therapy for failed surgical bioprostheses. However, massive biatrial enlargement can preclude delivery, leading to procedural failure.
