Myocarditis, or inflammation of the heart muscle, in children is a serious condition that can arise due to various factors. Among the most common causes are viral infections such as influenza, adenovirus, and rubella. Bacterial or other infectious agents can also lead to myocarditis. Furthermore, certain medications, chemicals, radiation, and autoimmune diseases causing inflammation in different organs of the body can also be contributing factors. Infections contracted by the mother during pregnancy can cause heart muscle inflammation in newborns.
The course of myocarditis varies greatly from child to child. While some children recover completely, others may develop severe heart failure or chronic heart disease. Statistically, although complete recovery is observed in approximately 10-20% of cases, a significant portion faces a long-term risk of chronic heart problems or heart failure. Symptoms may be less pronounced in children older than 2 years. Due to impaired blood flow in the heart, damage can develop in other organs such as the liver and kidneys.
Regular monitoring by a specialized pediatric cardiologist is vitally important for these children. Children under follow-up have the potential to develop rhythm disorders, heart failure, and other cardiac complications in the future.
