I05-I09: Chronic rheumatic heart diseases

I06: Rheumatic aortic valve diseases

Rheumatic aortic valve diseases are a group of conditions that affect the aortic valve in the heart. These conditions are often the result of rheumatic fever, an inflammatory condition that can develop after an infection with group A Streptococcus bacteria. The aortic valve, which is responsible for controlling the flow of blood from the heart to the aorta, can become damaged, causing problems with blood flow. Symptoms of these diseases can vary but often include fatigue, shortness of breath, chest pain, and fainting. The progression of these diseases depends on the extent of the damage to the valve and can range from minor symptoms to severe heart problems. Both the circulatory and cardiovascular systems are affected by these conditions. It's important to note that these diseases can have long term effects and if untreated, it can lead to serious complications.
