Overview
Medical management of patients with Ebstein’s anomaly consists of supportive care such as:
- Control of the heart rhythm with antiarrhythmic drugs
- Inotropic agents and diuretics for heart failure
- Anticoagulation in patients with atrial fibrillation and paradoxical embolization
Antiarrhythmics
Some Ebstein's anomaly patients present with an (antidromic) AV nodal reentrant tachycardia with associated pre-excitation. Among these patients, the preferred pharmacological treatment agent is procainamide. Since AV-blockade may promote conduction over the accessory pathway, drugs such as beta blockers, calcium channel blockers and digoxin are contraindicated.
If there is atrial fibrillation with pre-excitation, treatment options include procainamide, flecainide, propafenone, dofetilide and ibutilide since these medications slow conduction in the accessory pathway causing the tachycardia and should be administered before considering electrical cardioversion. Intravenous amiodarone may also convert atrial fibrillation and/or slow the ventricular response.
Anticoagulation
Warfarin is recommended for patients with Ebstein’s anomaly with a history of paradoxical embolus or atrial fibrillation.
Heart Failure Management
Diuretics may aid in reducing volume overload. Cardiac glycosides like digoxin can be used to maintain proper heart rhythm and increase contractility.
