The Role of Multimodality Imaging in Left Atrial Appendage Closure

Summary

The aim of the present prospective, randomized single-centre study is to examine the success rate, safety, overall preoperative and operative burden and long-time outcome of percutaneous left atrial appendage closure procedures after unimodal and multimodal preprocedural imaging. According to the investigators' primary hypothesis, simple, unimodal preprocedural imaging does not increase procedural burden of LAAC (total radiation dose, procedure time, fluoroscopy time, contrast amount). The investigators assume, that the success rate and safety of LAAC procedures is not reduced using unimodal preoperative imaging. Regarding to postoperative imaging, the investigators aim to compare the sensitivity of different imaging techniques in detecting postoperative complications. We assume, that multimodal imaging technique increases the accuracy and sensitivity of the detection of postoperative complications (PDL, device thrombi).
