However, device-related thrombus (DRT) may occur after LAAO implantation and poses significant diagnostic and treatment challenges.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>We describe a case of a patient who suffered an intracranial pontine haemorrhage while on anticoagulation with rivaroxaban for permanent atrial fibrillation and successfully underwent implantation of the LAAO device. Early follow-up transoesophageal echocardiography (TOE) with 3D multi-plane reconstruction revealed a large echo-dense mass on the left atrial aspect of the device. Cardiac computed tomography angiography confirmed a thrombus adherent to the LAAO device. After deciding on the treatment strategy, complete thrombus resolution was achieved at the 6 months follow-up and the patient was free of any thromboembolic and bleeding events.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Although DRT is a rare complication following LAAO procedure, an accurate diagnosis is crucial for the specific treatment. Multi-modality imaging approach with TOE and cardiac computed tomographic angiography as complementary methods is helpful to detect complications after LAAO procedure in challenging cases.<\/jats:p>\n
