Purpose
Rheumatic heart disease is the most common acquired heart disease in children in developing countries. The heart valve lesions produce severe hemodynamic changes due to scarring of the valves over time. Around 15.6 million people are affected by rheumatic heart disease (RHD), and 230,000 die around the globe annually. Valve repair should be the primary goal, although it is technically challenging because of the fact that rheumatic process evolves making repair outcomes variable.
Methods
We reviewed the literature for the various techniques done for mitral valve repair in children with rheumatic heart disease. Early and late results of repair were compared with the results found for mitral valve repair done for such children.
Results
Prosthetic heart valve implantation in children has major negative impact on their immediate- and long-term survival as well as on quality of their life. Valve repair is associated with improved ventricular function because the normal valve tissue and subvalvular apparatus are preserved, reduced complications related to prosthetic valve, and lower in-hospital and late mortality.
Conclusion
In children, the results of mitral valve replacement were found to be inferior to those of mitral valve repair. The reoperation rates are similar in patients undergoing initial repair or replacement, which favors repair as an option. In developing world, rheumatic mitral valve disease is more prevalent where adequate facilities for monitoring of prosthetic valve function and management of anticoagulation therapy are not easily available. Valve repair therefore should be the primary goal.
