Percutaneous transcatheter closure of the left atrial appendage with implant, including fluoroscopy, transseptal puncture, catheter placement(s), left atrial angiography, left atrial appendage angiography, radiological supervision and interpretation

Percutaneous transcatheter closure of the left atrial appendage with an implant is a minimally invasive procedure designed to reduce the risk of stroke in patients suffering from atrial fibrillation, a condition characterized by irregular heartbeats. This procedure is particularly important for individuals who are at an elevated risk for cardiac emboli, which are blood clots that can form in the heart and travel to the brain, leading to ischemic strokes. The left atrial appendage (LAA) is a small pouch located in the left atrium of the heart, and it is known to be a common source of these emboli in patients with atrial fibrillation. By closing off the LAA, the procedure aims to prevent blood clots from escaping into the bloodstream. The process involves several technical steps, including the use of fluoroscopy for imaging, transseptal puncture to access the left atrium, and the placement of a catheter to deliver the closure device. This procedure may also be referred to as percutaneous left atrial appendage transcatheter occlusion, highlighting its role in occluding the LAA to mitigate stroke risk. The access for this procedure is typically through the right femoral vein, where a small incision is made to facilitate catheter insertion. Overall, this intervention is a critical option for managing stroke risk in patients with atrial fibrillation, providing a less invasive alternative to surgical approaches.
