To describe percutaneous left atrial appendage closure (LAAc) in a patient with recurrent gastric ulcer bleeding with the help of the TrueFusion™ fusion-imaging system.

Method and results

In a patient with paroxysmal atrial fibrillation, the need for an effective oral anticoagulation and recurrent gastrointestinal bleeding, left atrial appendage closure (LAAc) was performed under guidance of the TrueFusion™ fusion-imaging technology (Siemens Healthineers, Erlangen, Germany) to enhance procedural precision, save radiation time and contrast dye. Left atrial appendage closure was performed with the use of a 20 mm Amplatzer Amulet™ (Abbott Laboratories, Chicago, IL, USA) using the TrueFusion™ system under mild sedation with minimal use of contrast. Intraprocedural transesophageal echocardiography revealed complete LAA occlusion without residual flow. The patient was uneventfully discharged on the second postoperative day.


LAAc using an integrated approach combining ultrasound and live fluoroscopy, as provided by the TrueFusion™, is safe and feasible. Target-oriented device navigation and synchronized image orientation as provided by fusion imaging may potentially be beneficial regarding radiation time, contrast dye and periprocedural risk of suboptimal device positioning.
