Key Result

Stent-assisted inferior vena cava downsizing enables successful valve-in-valve caval implantation, yielding durable outcomes when guided by accurate sizing and precise deployment.

Key Points

  • To explore the effectiveness of stent-assisted downsizing and ballooning for IVC tricuspid valve regurgitation treatment.
  • Utilized multimodality imaging for prosthetic dysfunction evaluation.
  • Performed stent-assisted IVC downsizing before valve-in-valve implantation.
  • Employed ballooning technique for valve expansion.
  • Achieved successful valve-in-valve implantation with durable outcomes.
  • Identified correct sizing as critical for procedure success.
  • Demonstrated precise deployment enhances treatment effectiveness.

Structured PICO

Does stent-assisted IVC downsizing enable successful valve-in-valve caval implantation in patients with prosthetic dysfunction after prior caval valve implantation?

P
Population
Patients with prosthetic dysfunction requiring reintervention after prior caval valve implantation
I
Intervention
Stent-assisted inferior vena cava (IVC) downsizing with a nonpremounted stent followed by balloon-expandable valve-in-valve caval implantation
O
Outcome
Successful valve-in-valve caval implantation

Stent-assisted IVC downsizing is a feasible technique to facilitate valve-in-valve implantation for treating prosthetic dysfunction after prior caval valve procedures.

Abstract

Comprehensive multimodality imaging is critical to identify prosthetic dysfunction and guide safe reintervention after prior caval valve implantation. Stent-assisted IVC downsizing can enable successful valve-in-valve caval implantation, with durable outcomes dependent on accurate sizing and precise deployment.
