Right ventricular hypertrophy in a 13-year-old child is unlikely to be cured. Right ventricular hypertrophy can be caused by congestive heart failure, pulmonary valve stenosis, hypertrophic obstructive cardiomyopathy and other causes. It is mainly due to the fact that in a pathological state, the ventricle is overloaded and requires greater force to pump blood out, so this part of the heart muscle becomes abnormally thickened leading to ventricular hypertrophy, which is usually irreversible. Right ventricular hypertrophy can be controlled, but not cured, by aggressive treatment. Therefore, it is unlikely that a 13-year-old child with right ventricular hypertrophy can be cured. In addition, it is recommended that children with right ventricular hypertrophy go to the hospital in time, follow the doctor’s instructions for treatment, and actively control the condition.
