I05-I09: Chronic rheumatic heart diseases

I07: Rheumatic tricuspid valve diseases

Rheumatic tricuspid valve diseases refer to a group of heart-related conditions that affect the tricuspid valve due to rheumatic fever. Rheumatic fever typically develops as a complication of untreated strep throat or scarlet fever, caused by Group A streptococcus bacteria. In this group of conditions, the heart's tricuspid valve, positioned between the right atrium and right ventricle, becomes damaged. This damage leads to a narrowing, leakage, or improper closing of the valve. Common symptoms can include fatigue, shortness of breath, fluid retention, palpitations, and swelling in the abdomen, ankles, or feet. Over time, without treatment, this can lead to worsening heart function and complications such as heart failure. The severity and progression of these conditions can vary greatly based on the extent of valve damage and the patient's overall health.
