Severity of rheumatic mitral stenosis in children
1Department of Cardiology, All India Institute of Medical Sciences, New Delhi.
Insights
In children with rheumatic mitral stenosis, severe pulmonary hypertension is common. This study analyzed 125 pediatric cases, finding a strong link between hypertension severity and critical mitral stenosis requiring surgery.
Area of Science:
- Cardiology
- Pediatric Rheumatology
Background:
- Rheumatic heart disease remains a significant cause of mitral stenosis globally.
- Pediatric cases of rheumatic mitral stenosis can progress rapidly, necessitating early intervention.
Purpose of the Study:
- To investigate the correlation between the severity of pulmonary venous and arterial hypertension and the degree of rheumatic mitral stenosis in children.
- To analyze clinical, hemodynamic, and operative findings in pediatric patients with rheumatic mitral stenosis.
Main Methods:
- Retrospective analysis of clinical, hemodynamic, and operative data from 125 children (up to 12 years old).
- Assessment of pulmonary venous and arterial hypertension severity.
- Evaluation of mitral stenosis severity during operative procedures.
Main Results:
- Nearly three-quarters of patients exhibited moderately severe to severe pulmonary venous and arterial hypertension.
- Operative findings revealed critical mitral stenosis in 69% of the analyzed cases.
- A subset of patients in India demonstrated rapid progression to severe mitral stenosis requiring surgery by age six.
Conclusions:
- Severe pulmonary hypertension is frequently associated with rheumatic mitral stenosis in children.
- The findings highlight the potential for rapid disease progression in pediatric rheumatic mitral stenosis, emphasizing the need for timely diagnosis and management.
- Early surgical intervention is crucial for managing critical mitral stenosis in affected children.
Abstract:
Clinical, hemodynamic and operative findings of 125 children, up to the age of 12 years, were analysed to determine if the severity of pulmonary venous and arterial hypertension correlated with the severity of rheumatic mitral stenosis. Moderately severe to severe pulmonary venous and arterial hypertension was found in almost three-quarters of the patients. Operative findings indicated critical mitral stenosis in 69% of the cases. In India, following rheumatic fever, some patients follow an unusually rapid course in developing mitral stenosis severe enough to require operative treatment, even at the age of six years.
