The symptoms of tetralogy of Fallot can appear after birth or within a few weeks, manifested as bruising, and gradually worsen. The first three are primary lesions, which are of great significance; and right ventricular hypertrophy is a secondary change, which is the consequence of the above malformations. Echocardiography has very specific manifestations of this disease and can be used as a basis for diagnosis of this disease.
