Carpentier Classification The volume of the true RV is adequate
A large atrialized component of the RV exists, but the anterior leaflet of the TV moves freely
The anterior leaflet is severely restricted in its movement and may cause significant obstruction of the RVOT
Almost complete atrialization of the RV except for a small infundibular component

Surgical Intervention
Surgeons with training and expertise in CHD should perform tricuspid valve repair or replacement with concomitant closure of an ASD, when present, for patients with Ebstein’s anomaly with the following indications:
Symptoms or deteriorating exercise capacity. (Level of Evidence: B)
Cyanosis (oxygen saturation less than 90%). (Level of Evidence: B)
Paradoxical embolism. (Level of Evidence: B)
Progressive cardiomegaly on chest x-ray. (Level of Evidence: B)
Progressive RV dilation or reduction of RV systolic function. (Level of Evidence: B)

Catheter Intervention
Class I Adults with Ebstein’s anomaly should have catheterization
performed at centers with expertise in catheterization and management of such patients. (Level of Evidence: C)
Class IIa Catheter ablation can be beneficial for treatment of recurrent
supraventricular tachycardia in some patients with Ebstein’s anomaly. (Level of Evidence: B)

Accessory Pathway Mediated SVT
Localization of accessory pathways is often challenging & > 50 % of patients have multiple accessory pathways
The success rate for catheter ablation is lower in Ebstein anomaly (≤81 %) patients compared with patients with structurally normal hearts (≥95 %)
Rarely, right coronary artery stenosis has been seen following catheter ablation
