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
Medical Therapy
ACC / AHA 2008 Guidelines- Recommendation for Medical Therapy- Ebstein's Anomaly of the Tricuspid Valve(DO NOT EDIT)[1]
| Class I |
| "1.Anticoagulation with warfarin is recommended for patients with Ebstein’s anomaly with a history of paradoxical embolus or atrial fibrillation. (Level of Evidence: B) " |
Ebstein's cardiophysiology typically presents as an (antidromic) AV nodal reentrant tachycardia with associated pre-excitation. In this setting, the preferred pharmacological treatment agent is procainamide. Since AV-blockade may promote conduction over the accessory pathway, drugs like 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.
Warfarin is recommended for patients with Ebstein’s anomaly with a history of paradoxical embolus or atrial fibrillation.
Diuretics aid in flushing excess fluid from the body, thereby easing strain on the heart.
Cardiac glycosides are used to maintain proper heart rhythm while increasing the strength of each contraction.
