Congenital mitral valve surgery: techniques and results

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Congenital mitral valve lesions are infrequent cardiac abnormalities.
• Conservative surgical approaches are generally preferred.
• Complex anatomical variations may necessitate valve replacement for optimal outcomes.

Purpose of the Study:

• To review the long-term efficacy of established conservative and replacement surgical treatments for congenital mitral valve lesions.
• To explore emerging technical advancements in managing these rare conditions.

Main Methods:

• Literature review of classical and novel surgical techniques.
• Analysis of long-term follow-up data for conservative and replacement surgeries.
• Evaluation of echocardiographic advancements in diagnosis and treatment planning.

Main Results:

• Conservative surgery demonstrates favorable long-term results with low reoperation rates, except in cases of mitral valve stenosis.
• The Ross II operation, utilizing a pulmonary autograft, presents a viable, albeit complex, option for pediatric patients unsuitable for prosthetic devices.
• Echocardiography has significantly improved the understanding of mitral valve anatomy and function, guiding surgical decisions.

Conclusions:

• Current trends in congenital mitral valve surgery emphasize avoiding multistage procedures.
• Valve replacement using biologic material, such as in the Ross II procedure, requires ongoing clinical assessment.
• Improved diagnostic imaging facilitates more precise surgical interventions and better patient selection.
