This study reports the first successful closure of paravalvular leak (PVL) using only three-dimensional transesophageal echocardiography (3D-TEE) guidance. This fluoroscopy-free approach offers a viable alternative for select patients needing PVL treatment.
Area of Science:
- Cardiology
- Medical Imaging
- Interventional Cardiology
Background:
- Transcatheter paravalvular leak (PVL) closure traditionally relies on fluoroscopy.
- Fluoroscopic imaging limitations exist for certain patient groups and in settings with limited availability.
- Alternative imaging modalities are needed for PVL closure.
