We unpack the FDA 510(k) clearance for Anumana's WatchMate Software, a deep-learning tool that reconstructs 3D models of the left atrial appendage from standard 2D ultrasound. Discover how it stacks up against human physicians and CT scans, its clinical trial results, and the practical IT realities of deploying AI in the cath lab.
Key points
WatchMate Software is cleared for pre-procedural planning and device sizing for left atrial appendage closure (LAAC) procedures.
It uses a multi-stage AI pipeline to reconstruct a 3D model and estimate a landing zone from 2D transesophageal echocardiography (TEE) images.
In a 100-subject prospective study, WatchMate achieved a mean absolute deviation of 3.1 ± 3.4 mm compared to a CT reference standard, outperforming the human 2D TEE average of 5.2 ± 3.4 mm.
The software operates locally on a Linux workstation with an NVIDIA GPU and an iPad mobile interface, completely bypassing cloud connectivity.
Clearance is based on substantial equivalence to the TruPlan CT Imaging Software, highlighting a shift from CT-based planning to TEE-based AI planning.
Real-world limitations apply: 100 subjects were enrolled, but only 72 were included in the per-protocol population due to unanalyzable data or 2D-3D inconsistency flags.
