Umbrella devices for percutaneous left atrial appendage (LAA) occlusion depend on anatomy. This study demonstrates the successful use of a patent foramen ovale (PFO) closure device for LAA occlusion in a unique anatomical case.

Area of Science:

Cardiovascular Interventions
Medical Device Technology
Anatomical Adaptations in Cardiac Procedures

Background:

Percutaneous left atrial appendage (LAA) occlusion is a standard procedure for stroke prevention.
Existing umbrella-shaped devices have limitations influenced by specific LAA anatomies.
Anatomical variations, such as circumferential ridges, can complicate standard occlusion device deployment.

Keywords:

Atrial appendage Atrial fibrillation Cardiac catheterization Therapeutic occlusion Thoracic surgery
