Abstract Background Bilateral stroke following radiofrequency catheter ablation is an unusual complication click here and may result in bilateral altitudinal visual field defects.Bilateral altitudinal visual field defects usually result from prechiasmal pathology causing damage to both retinas or optic nerves and rarely from bilateral symmetric damage to the post chiasmal visual pathways.Case presentation A 48-year-old man complained of visual disturbance on wakening following radiofrequency catheter ablation.The read more patient had a CHADS score of 1 pre-operatively and no complications were noted intra-operatively.

Examination revealed a bilateral superior altitudinal defect and MRI of the brain showed multifocal areas of infarction predominantly involving the occipital lobes which correlated to with the visual deficits.Conclusion While the risk of thromboembolism and perioperative stroke during radiofrequency catheter ablation is small, it is not insignificant.
