Caval valve implantation (CAVI) for severe tricuspid regurgitation can be complicated by device migration. A valve-in-valve approach successfully treated migrated devices in two high-risk patients, offering a less invasive solution.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Caval valve implantation (CAVI) is a percutaneous treatment for severe tricuspid regurgitation (TR) in high-risk patients.
- A challenge in CAVI is the lack of calcified structures for device anchoring, potentially causing paravalvular leak or migration.
- Device migration is a rare but serious complication of transcatheter interventions.
