A 79-year-old male patient was scheduled forpercutaneous left atrial appendage (LAA) closure.He had history of atrial fibrillation and had been admitted to Neurology 1 month prior for left thalamichemorrhage. After anticoagulation was reversedwith prothrombin complex and K vitamin andacenocumarol was suspended, he presented withnew neurological symptoms, and cerebral magneticresonance showed several ischemic infarctions inthe right hemisphere. This prompted the currentintervention, upon performance of a transoesophageal echocardiogram (TEE).
