Mitral valve repair in children using Carpentier's techniques

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Valvular Heart Disease

Background:

• Rheumatic mitral valve disease is a significant cause of mitral valve incompetence in children.
• Surgical treatment options for pediatric mitral valve disease include repair and replacement, with ongoing debate regarding the preferred method.
• Carpentier's techniques offer a standardized approach to mitral valve repair.

Purpose of the Study:

• To evaluate the efficacy and long-term outcomes of mitral valve repair using Carpentier's techniques in pediatric patients.
• To compare mitral valve repair with replacement in children with rheumatic mitral valve disease.

Main Methods:

• Retrospective review of 130 children (aged 3-15 years) who underwent mitral valve surgery between 1992 and 1997.
• Patients were treated using Carpentier's mitral valve repair techniques.
• Valve dysfunction was classified according to Carpentier's classification (Types II, III, and combined II/III).

Main Results:

• A total of 111 cases (85%) involved rheumatic valve disease.
• Early mortality was low (0.7%). Long-term survival was high (99.2%).
• Excellent functional outcomes were observed: 96.8% were free from reoperation, and 89% had no significant residual stenosis or insufficiency on echocardiography. No thromboembolisms occurred.

Conclusions:

• Mitral valve repair utilizing Carpentier's techniques is a safe and effective procedure for pediatric mitral valve incompetence.
• This approach demonstrates superior long-term results, including low reoperation rates and excellent functional recovery, even in cases of rheumatic heart disease.
• Mitral valve repair is recommended as the preferred surgical strategy for children with mitral valve incompetence.
