Abstract
Catheter ablation is a commonly performed procedure in patients with Wolff-Parkinson-White syndrome. A 56-year-old man developed an acute ischemic stroke immediately after undergoing radiofrequency catheter ablation of the left-sided accessory pathway. Neuroimaging revealed complete occlusion of the proximal middle cerebral artery. Mechanical thrombectomy (MT) was performed with successful retrieval of the thrombo-embolus. Histopathological examination of the thrombo-embolus confirmed organic cardiac tissue. The patient was later discharged from the hospital with no neurologic deficit. There is no report of successful MT in patients with large-vessel occlusion because of the embolization of cardiac tissue after catheter ablation. This report highlights the need to remain vigilant for signs of stroke after any cardiac intervention.
