Brief 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
Detailed Description: Left atrial appendage closure LAAC is an increasingly used non-pharmacologic strategy to prevent stroke in patients with atrial fibrillation who have absolute or relative contraindications to long-term oral anticoagulant therapy mainly due to previous major bleeding or high bleeding risk As the majority of candidates are elderly patients with multiple morbidities the reduction of procedural burden is of huge significance

The aim of the present prospective randomized single-centre study is to examine the non-inferiority of unimodal MDCT vs multimodal MDCTTOE preprocedural imaging in percutaneous left atrial appendage closure The investigators are going to assess the success rate safety and complications of LAAC procedures and determine the procedural burden total radiation dose procedure time fluoroscopy time contrast amount of the interventions after preprocedural unimodal and multimodal appendage characterization and device sizing Multimodal procedural guidance 2D3D TOE fluoroscopy-angiography and multimodal postprocedural imaging 2D3D TOE MDCT is going to be used to identify complications peri-device leak thrombus The investigators are planning to compare the accuracy and additive value of different postoperative imaging techniques
