Dilemmas in the management of rheumatic heart disease

Insights
Rheumatic heart disease (RHD) is a significant health issue in India. School-based prevention programs are crucial for early intervention and reducing the long-term impact of RHD on children.
Area of Science:
- Cardiology
- Public Health
- Pediatrics
Background:
- Rheumatic heart disease (RHD) presents a substantial and ongoing healthcare challenge in India.
- The absence of a vaccine makes RHD control difficult, necessitating alternative preventive strategies.
- Schools, particularly those serving underprivileged populations, are identified as critical centers for primary and preventive healthcare.
Purpose of the Study:
- To emphasize the importance of school-based prophylaxis in the prevention of Rheumatic Heart Disease (RHD).
- To outline the roles of primary, secondary, and tertiary prevention in managing RHD.
- To discuss current treatment options for valvular heart conditions resulting from RHD and underscore the need for preventive measures.
Main Methods:
- The abstract discusses the implementation of school prophylaxis as a primary preventive measure against RHD.
- It reviews various surgical interventions for valvular heart disease, including mitral stenosis (closed mitral valvotomy, open mitral valvotomy, interventional mitral valvotomy), mitral regurgitation, aortic stenosis, and aortic regurgitation.
- The text highlights the palliative nature of current treatments for established valve damage and stresses the importance of careful assessment in combined valve disease.
Main Results:
- Current treatments for damaged heart valves are palliative, not curative.
- Valvotomy is often preferred over valve replacement for conditions like mitral stenosis and aortic stenosis when feasible.
- Medical management is recommended for mild to moderate mitral regurgitation, while advanced cases may require repair or replacement.
Conclusions:
- Preventing RHD through school-based programs is paramount, as existing treatments for valve damage are palliative.
- Tertiary prevention strategies can help minimize further damage after heart valves are affected.
- The Indian Medical Association has a significant role to play in RHD prevention efforts to ensure children in India grow up free from the disease.
Abstract:
Rheumatic heart disease (RHD) is a major health care problem in India and will continue to be so for few more decades. As there is no vaccine against RHD, it is difficult to control the disease. Besides RHD, most children have other preventable ailments as well. Hence the schools, specially for the poor, must act as primary and preventive health care centres. Prevention of RHD starts with school prophylaxis. Primary, secondary and tertiary prophylaxis play their roles afterwords. After the heart valves have been damaged, tertiary prevention might minimise further damage. For mitral stenosis, closed mitral valvotomy (CMV), open mitral valvotomy (OMV) and interventional mitral valvotomy (IMV) are the different options but none is curative. Valve replacement poses many problems and therefore valvotomy is deferred as far as possible. Mild or moderate mitral regurgitation (MR) is best treated medically. For more advanced disease repair or replacement is the option. For aortic stenosis (AS), valvotomy may be preferred to replacement wherever feasible and for aortic regurgitation (AR) repair is not yet well established. In combined mitral and aortic valve disease it is important to assess both the valves carefully and try to repair one or both the valves and to avoid double valve replacement as far as possible. Once the heart valve is damaged any treatment is palliative, hence all efforts should be directed towards prevention of RHD. Indian Medical Association can play a major role in this endeavour and help children in India to grow up free from RHD.
