A left atrial diverticulum (LAD) refers to a pouch-like structure with a saclike shape with a broad-based ostium and a smooth contour to its body. They are considered an anatomical variant.
Complications
- some suggest that there may be a possible latent relationship between LA diverticulum and systemic embolic events during AF ablation 2.
