The electrophysiologic basis and management of symptomatic recurrent tachycardia in patients with ebstein's anomaly of the tricuspid valve

Contemporary Management of Arrhythmias During Pregnancy

“…SVT is usually well tolerated but can result in hemodynamic deterioration in patients with structural heart disease and result in impaired fetal blood flow. 29,30 Atrioventricular Nodal Reentrant Tachycardia AVNRT in pregnant patients should initially be managed with the avoidance of precipitating factors and the use of vagal maneuvers to terminate acute episodes of the arrhythmia. In hemodynamically stable patients who do not respond to vagal maneuvers, adenosine is the drug of choice as it is safe and terminates ≈90% of paroxysmal SVT.…”

ACC/AHA 2008 Guidelines for the Management of Adults With Congenital Heart Disease

“…Supraventricular tachycardia related to accessory pathways is a frequent accompaniment of Ebstein's anomaly. 625 Catheter ablation has become the most attractive treatment for this condition, although the procedure can be quite challenging. Overall, success rates are lower and recurrence rates higher than those reported for ablation in a structurally normal heart, 141,143 in part because multiple accessory pathways are present in nearly 50% of these patients.…”
