Left atrial appendage occlusion
Left atrial appendage occlusion (pronunciation: left ey-tree-uhl uh-pen-dij uh-kloo-zhuhn) is a medical procedure that aims to reduce the risk of stroke in patients with atrial fibrillation. The procedure involves sealing off the left atrial appendage to prevent the formation and release of blood clots.
Etymology
The term "left atrial appendage occlusion" is derived from the following components: "left" and "atrial" refer to the left atrium of the heart, "appendage" refers to the small, ear-shaped sac in the muscle wall of the left atrium, and "occlusion" refers to the blockage or closing of a blood vessel or hollow organ.
Procedure
The left atrial appendage occlusion procedure is performed by a cardiologist who uses a small device to seal off the left atrial appendage. The device is inserted through a small incision in the groin and guided to the heart through a vein. Once the device is in place, it helps prevent blood clots from forming in the left atrial appendage and being released into the bloodstream.
