IVC Tric Valve Regurgitation Treatment With Ballooning Expanding the Valve After Downsizing With a Nonpremounted Stent

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?

Population

Patients with prosthetic dysfunction requiring reintervention after prior caval valve implantation

Intervention

Stent-assisted inferior vena cava (IVC) downsizing with a nonpremounted stent followed by balloon-expandable valve-in-valve caval implantation

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.

Main Result

Absolute Event Rate: 0% vs 0%

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.
