Malignant Rheumatic Heart Disease Presenting as Quadrivalvular Stenosis

Area of Science:

• Cardiology
• Rheumatology
• Pediatric Cardiology

Background:

• Rheumatic heart disease (RHD) can affect heart valves, but quadrivalvular involvement is exceptionally rare.
• Simultaneous involvement of all four heart valves typically results from a combination of etiological factors.
• Rheumatic fever is a potential unitary cause for quadrivalvular damage, alongside myxomatous degeneration.

Observation:

• A 16-year-old male presented with progressive dyspnea on exertion and congestive heart failure.
• Physical examination revealed stenosis of the mitral, aortic, and tricuspid valves.
• The patient had a documented history of rheumatic fever in childhood.

Findings:

• Transthoracic echocardiography confirmed quadrivalvular involvement.
• This presentation represents a rare occurrence of rheumatic quadrivalvular damage.
• The patient's juvenile age group is likely the first reported for this condition.

Implications:

• Highlights the potential for severe, multi-valve rheumatic heart disease in adolescents.
• Suggests the importance of considering rheumatic etiology even in rare presentations of quadrivalvular disease.
• Emphasizes the need for early diagnosis and management of RHD to prevent advanced valvular pathology.
