Congenital heart disease is a malformation that newborns are likely to have from birth, accounting for about 1%, of which single ventricle congenital heart disease is the rarest congenital heart disease but should not be ignored because it has a high potential to lead to heart failure in children. To treat this disease, the Fontan surgery method is quite commonly applied today to help patients improve the condition of single ventricle congenital heart disease.

Heart surgery is a method used to treat patients with a number of cardiovascular diseases, which can be open surgery or closed surgery. It is especially important that after cardiovascular surgery, patients need to be closely monitored for their health status as well as care and resuscitation after cardiovascular surgery to detect early abnormalities and promptly take them to a medical facility for treatment.
