Cardiac Phantom Model for Left Atrial Appendage Occlusion Procedures
May 3, 2024
A cardiac phantom model has been developed as an experimental and demonstrative tool for left atrial appendage (LAA) occlusion procedures. In patients with non-valvular atrial fibrillation, blood flow stagnation in the LAA, a small protrusion extending from the left atrium, can induce clot formation and subsequent stroke. The heart phantom offers a platform to evaluate the efficacy of occlusion devices and features highly-regulated pulsatile flow, the ability to modulate the base diameter and wall thickness of the LAA, and visualization of flow dynamics within the appendage.
