Transcatheter Tricuspid Valve-In-Valve Implantation in Patients with Tricuspid Bioprosthetic Valve Degeneration at High Surgical Risk: A Multicenter Case Series

Summary

Background:

Transcatheter tricuspid valve-in-valve implantation (TVIV) is an attractive yet under-explored alternative to redo valve surgery. 

Objectives:

To report the multicenter TVIV experience in Israel.

Methods:

We approached multiple centers and collected data regarding seven TVIV cases. 

Results:

The study group comprised seven participants: five females and two males, with a mean age of 63 ± 12 years and EuroSCORE-II 13.6 ± 3.3%. Follow-up ranged from 3 to 21 months (mean 8 ± 6 months). All presented with advanced heart failure. The indication for valve intervention was a predominant tricuspid stenosis in three patients, significant tricuspid regurgitation in one and a mixture in three. Six procedures were conducted via a transfemoral approach and one by transatrial access. The Edwards SAPIENTM XT valve was used in four cases and the SAPIENTM 3 in three. Without pre-stenting/rapid pacing, all participants underwent successful valve implantation. Mean transvalvular gradient decreased from 11 ± 3 mmHg to 6 ± 3 mmHg (P = 0.003) and regurgitation decreased from moderate/severe (in four cases) to none/trace (in six of the seven cases). One patient remained severely symptomatic and died 3.5 months after the implantation. All others achieved a functional capacity improvement and amelioration of symptoms soon after the implantation, which persisted during follow-up. 

Conclusions:

TVIV may be a safe and effective strategy to treat carefully selected patients with degenerated bioprosthetic tricuspid valve at high operative risk.
