[Product Collection] 03 Simulation Model – Left Atrial Appendage Occlusion Heart Model | Precise Deployment for Intuitive Evaluation

Atrial fibrillation (AF) is a common cardiac arrhythmia seen in clinical practice, affecting over 40 million patients worldwide. During AF, blood flow within the left atrial appendage becomes sluggish, increasing the risk of clot formation. If these clots dislodge, they can travel to the brain, leading to stroke—a condition with extremely high rates of disability and mortality. Left atrial appendage closure has emerged as a critical strategy for preventing stroke in AF patients. This procedure involves placing a closure device into the left atrial appendage, effectively blocking the pathway that allows clots to enter the bloodstream. The surgery relies on specialized instruments, including delivery sheaths, guidewires, and dedicated occluders such as the Watchman or LAmbre devices. However, in real-world clinical settings, the left atrial appendage exhibits diverse anatomical shapes—ranging from "chicken-wing" to "cauliflower" or "windsock" types—and is closely situated near critical structures like pulmonary veins and coronary arteries. As a result, ensuring the stability of these devices in the complex intracardiac environment and achieving optimal apposition of the occluder during surgery remain challenging tasks that are difficult to predict preoperatively. Additionally, the varying sizes and irregular inner surfaces of the left atrial appendage mean that improper handling during the procedure could easily lead to serious complications, such as pericardial tamponade or device displacement—both of which demand exceptional spatial awareness and precise instrument control from the surgeon. Traditional training methods often fall short in replicating the true anatomical variations and surgical risks involved, making the development of realistic left atrial appendage closure heart models essential for overcoming these technical hurdles.
