Transseptal Mitral Valve-in-Valve Implantation Using an Arteriovenous Loop

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.
