Modified carpentier's technique for Ebstein's anomaly repair

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Cardiac Valve Repair

Background:

• Ebstein's anomaly is a rare congenital heart defect affecting the tricuspid valve.
• Surgical repair aims to restore right ventricle function and tricuspid valve competence.
• The modified Carpentier's technique offers a specific approach to repair.

Purpose of the Study:

• To evaluate the outcomes of a modified Carpentier's technique for Ebstein's anomaly repair.
• To assess functional and anatomical recovery of the right ventricle and tricuspid valve post-surgery.

Main Methods:

• Retrospective analysis of 52 patients operated between August 2005 and December 2010.
• Utilized a modified Carpentier's technique involving leaflet mobilization, atrialized chamber plication, leaflet relocation, and annuloplasty.
• Detailed surgical steps included detachment and repositioning of tricuspid leaflets to the normal annulus.

Main Results:

• Significant reduction in tricuspid regurgitation from 3.72 to 1.56 (p < 0.01).
• Improvement in NYHA functional class from 2.53 to 1.14 (p < 0.01).
• One hospital death (1.95%); no long-term mortality or reoperations after a mean follow-up of 42.4 months.

Conclusions:

• The modified Carpentier's technique achieves satisfactory outcomes for Ebstein's anomaly repair.
• Complete anatomical and functional recovery of the right ventricle and tricuspid valve is feasible.
• This technique demonstrates safety and efficacy in managing Ebstein's anomaly.
