About

Atrial fibrillation is the most common rhythm disorder, affecting 2 to 3 percent of the population. One of the major complications is the occurrence of thromboembolic events, the thromboembolic risk can be predicted by the ChadsVasc score. Anticoagulant treatment is therefore almost always indicated, however, in view of the target population, anticoagulant treatment is sometimes contraindicated, justifying the appearance of alternative treatment such as occlusion of the left auricle by surgical or percutaneous means, with the placement of a prosthesis in the left auricle.

Image fusion is a new imaging technique aimed at improving the spatial view of 2D images (made during a catheterization session) by repositioning in real time a 3D model obtained by reconstruction from scanner images of the structure of interest. Once the model has been redesigned, it follows all the consequences that the hemodynamicist wants to take and thus guides the gesture as well as possible.

The purpose of this project is to evaluate the contribution of image fusion to per cutaneous occlusion procedures of the left atrium. This contribution will be evaluated by comparing the procedure time, the irradiation time, the amount of contrast material used between the procedures performed with the image fusion technique and without this new technique.
