ADAS 3D LA

Revealing fibrotic substrate in the atria

ADAS 3D LA enables better visualize the fibrotic substrate in the LA for pre and peri-procedural clinical decision making. It is intended for the electrophysiologist to visualize the distribution and quantify the amount of enhanced fibrosis in the LA to differentiate the fibrotic substrate and the healthy tissue including identifying gaps in previously created lesions.

What it does

ADAS 3D LA provides tools for defining the shape of the LA from 3D LGE MRI DICOM data. It then automatically computes the IIR value of the atrial wall and quantifies the fibrosis, the atrial volume. It also allows exporting the segmented LA 3D shape and associated fibrosis into formats compatible with EP navigation systems.
