The left appendage occlusion device is used in procedures such as percutaneous transluminal left atrial appendage occlusion and thoracoscopic left atrial appendage closure. Left appendage occlusion device controls the electrical impulses during atrial fibrillation. During atrial fibrillation, blood clots are pumped out of the heart. This blood can form clots in the atria and LAA. This medical condition can cause a stroke. Left appendage occlusion device is an interventional device used to prevent stroke in atrial fibrillation. Left appendage occlusion device helps in reducing the risk of secondary stroke and emboli because of atrial fibrillation.
The global left appendage occlusion device market is expected to grow rapidly during the forecast period. Clinical evidence of the efficiency of left appendage occlusion devices compared to the standard therapeutic treatment such as warfarin and dabigatran increased awareness levels, and new product launches in new countries are key factors boosting the market growth. However, the complicated implantation procedures and need of experienced surgeons are restraining factors for the market. The stringent regulation procedures for the approval of devices are hindering the new product launches. The vendors focus on clinical trials for new product launches in the high potential market such as the US and the Asia Pacific.
