Abstract

Transient global amnesia (TGA) is characterised by the sudden onset of isolated anterograde amnesia, which resolves within 24 hours. Here, we discuss the case of a 63-year-old woman who underwent a transoesophageal echocardiogram (TOE) as part of her workup for pulmonary hypertension. She was well on the morning of the procedure, and following consent, underwent transoesophageal echocardiography without sedation. The procedure was uncomplicated with normal observations throughout, confirming a suspected secundum atrial septal defect. Immediately following oesophageal extubation, it was noted that the patient was disoriented. The physical neurological examination was unremarkable. Urgent MRI of the brain showed normal anatomy; a diagnosis of TGA was made. Within 10 hours of onset, the patient was back to her baseline. Isolated anterograde amnesia following transoesophageal echocardiography should raise the clinical suspicion of TGA. Prompt clinical examination and support from other specialties are paramount in making the right diagnosis.
