A novel surgical technique effectively corrects Ebstein's anomaly, restoring tricuspid valve and right ventricle function. This procedure offers excellent early and midterm outcomes for patients with this congenital heart condition.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Congenital Heart Disease

Background:

  • Ebstein's anomaly is a rare congenital heart defect affecting the tricuspid valve and right ventricle.
  • Traditional surgical approaches have limitations in fully restoring normal cardiac function.

Purpose of the Study:

  • To introduce and evaluate a new surgical procedure for Ebstein's anomaly.
  • To assess the restoration of tricuspid valve and right ventricular function after the new procedure.

Main Methods:

  • A cohort of 34 consecutive patients with Ebstein's anomaly underwent the novel repair technique.
  • The procedure involves reattaching displaced leaflets, excising atrialized portions, and plicating the annulus.
  • Autologous pericardium was used to create new leaflets in cases of severe septal leaflet hypoplasia.

Main Results:

  • All 34 patients survived the surgery with uneventful recovery.
  • Postoperative echocardiography confirmed the disappearance of tricuspid incompetence in 29 patients and mild incompetence in 5.
  • Significant reduction in right ventricular size and complete resolution of the atrialized segment were observed.

Conclusions:

  • The described surgical procedure offers anatomical correction of Ebstein's anomaly.
  • Satisfactory early and midterm results demonstrate the efficacy of this new approach.
  • Improved exercise tolerance and normal cardiac function were noted in follow-up.
