On postoperative day 2, the patient complained of a feeling of a bilateral “C”-shaped area with heat waves that were fixed in his left visual fields that lasted for about 40 min and resolved spontaneously. The optical coherence tomography (OCT) performed revealed no abnormalities, and there have since been no more episodes.įigure 2: Optical coherence tomography scan from the patient of case 2, performed 2 days after the end of symptomsĪ 33-year-old man with no previous history of migraines or visual symptoms was submitted to a cryoablation procedure in arrhythmogenic foci originating within the pulmonary veins. Ophthalmological evaluation was as innocent as the one from case 1. ![]() The episodes of headache and visual field disturbances had subsided 2 days before. On postoperative day 10, he went to a follow-up ophthalmology appointment. He was discharged with pain-relieving medications. His neurological examination was unremarkable. He was hemodynamically stable and apyretic. On postoperative day 6, the boy developed a new episode with the same characteristics as mentioned above this motivated a visit to the emergency room. He also mentioned mild paresthesias in his parietal regions. On postoperative day 4, he complained of two biparietal headache episodes that lasted about 15 min each and were associated with blurry vision and a white haze in the temporal visual fields of both eyes. There have been no other episodes.Ī 12-year-old male child with no relevant medical or ophthalmological priors was submitted to a transseptal ablation procedure for cardiac dysrhythmia. Her visual symptoms had subsided the day before, but she still complained of slight headache and bilateral retro-orbital pressure. She had a follow-up ophthalmology appointment 5 days postoperatively. Magnetic resonance imaging (MRI) was not available in the emergency setting, but computerized tomography (CT) scan showed no hemorrhage or other abnormalities.įigure 1: Computerized tomography scan from the patient of case 1 obtained 2 days after the ablation procedureĪfter being evaluated by the neurology department, she was diagnosed with migraine with aura and discharged home with symptomatic medication (ibuprofen and acetaminophen in case of new onset of symptoms). Thorough clinical examination and neurological evaluation were normal. The patient went to the emergency department. On postoperative day 2, the patient developed a right parietal headache and the same bilateral visual symptoms that she kept describing as scintillating dots and lines in her right visual field. On postoperative day 1, she suffered a new episode of the same visual disturbance bilaterally, that lasted for approximately 20 min, and was followed by left hemicranial pain referred to the retro-orbital region and accompanied by nausea and photophobia. The symptoms ended as abruptly as they had started and were not associated with headache. She also complained of nausea and vomiting. Later on that day, she developed bilateral visual teichopsia on the right visual fields accompanied by photophobia that subsided after 30 min. Six hours after the procedure, the patient developed an acute onset of a sharp headache in the frontal region, accompanied by a subjective feeling of ocular pressure in both eyes that lasted for 5 min. #KALEIDOSCOPE VISION STROKE FULL#Full clinical and neurological examination might be necessary to exclude stroke or other life-threatening conditions, and thus, neuroimaging remains crucial in the evaluation of these symptoms.Ī 27-year-old woman with a history of drug-resistant ventricular tachycardia was submitted to a cardiac ablation procedure of a concealed left lateral accessory pathway through a transseptal approach. The patient should be made aware that it is usually a self-limited situation and that it has no long-term consequences on vision. The exact physiopathological mechanism is yet to be discovered. Visual symptoms after catheter ablation are a reported complication of the procedure, mainly after transseptal catheterization. Visual symptoms after a cardiac ablation procedure: A report of three cases. #KALEIDOSCOPE VISION STROKE HOW TO#How to cite this article: Monteiro CM, B. Keywords: Cardiac ablation, transseptal catheterization, visual symptoms The visual disturbances subsided spontaneously, and none of the patients developed any kind of permanent visual damage. Neurological and ophthalmological evaluations were always unremarkable even when performed during the episodes. ![]() The current study reports three cases of both adult and pediatric patients with a history of self-limited episodes of visual symptoms following ablative procedures for cardiac dysrhythmias. ![]()
