Summary
Carpentier's procedure for Ebstein's anomaly requires precise preoperative evaluation of the tricuspid valve. Conservative plication of the atrialized ventricle is favorable, avoiding annulus constriction and conduction system injury.
Area of Science:
- Cardiology
- Cardiac Surgery
- Congenital Heart Disease
Background:
- Ebstein's anomaly is a rare congenital heart condition affecting the tricuspid valve.
- Carpentier's procedure is a surgical technique used to repair the tricuspid valve in cases of Ebstein's anomaly.
Observation:
- Two adult patients with Ebstein's anomaly underwent Carpentier's procedure.
- The first case involved longitudinal plication of the atrialized ventricle with an uneventful recovery.
- The second case presented with restricted anterior leaflet motion, necessitating tricuspid valve replacement due to residual regurgitation and right heart failure.
Findings:
- Preoperative echocardiography is crucial for assessing tricuspid valve leaflet mobility and subvalvular anatomy.
- Longitudinal plication of the atrialized ventricle, if excessive, can lead to annular constriction.
- Conservative plication limited to the free wall may be preferable to avoid complications.
Implications:
- Accurate preoperative assessment, particularly of the anterior leaflet and subvalvular structures, is essential for successful Carpentier's procedure.
- Careful surgical technique, including conservative plication, can prevent complications like annular stenosis and conduction system damage.
- This study highlights the importance of individualized surgical approaches in managing Ebstein's anomaly.
