Intraoperative Supra-Ventricular Tachycardia Revealing Intermittent Wolff-Parkinson-White Syndrome

Wolff-Parkinson-White Syndrome (WPW) is a congenital cardiac anomaly characterized by the presence of an accessory atrioventricular cardiac bundle called the Kent Bundle. Discovered by Wolf, Parkinson, and White, this condition can result in recurrent, sometimes fatal tachyarrhythmias. WPW is relatively rare, affecting approximately 0.1% to 0.3% of the general population. Its diagnosis relies on electrocardiography. Its management depends on the clinical presentation of each patient, varying in accordance with the severity of symptoms. It can range from vagal maneuvers and first-line anti-arrhythmic drugs to radiofrequency ablation in refractory cases. In this report, we present the case of a 40-year-old man undergoing surgery to remove a urachal cyst. During the intraoperative period, supra-ventricular tachycardia emerged, revealing a previously undiagnosed intermittent WPW syndrome.
