Left atrial appendage occlusion and peri-device leaks
A series of illustrations for a research article published in Structural Heart investigating the clinical significance and diagnostic assessment of peri-device leaks (PDL) after interventions targeting the left atrial appendage (LAA), for the reduction of cardioembolic risk in individuals with nonvalvular atrial fibrillation.
These illustrations explore a few of the anatomical considerations and possible pathological mechanisms concerning PDL after LAA occlusion or closure procedures. These types of patient-to-patient variations and challenges in device planning, placement, and outcomes demonstrate an opportunity to develop better modalities to identify and quantitate PDL.
