The heart can also be affected by congenital diseases. These diseases include failure to close the oval hole, which occurs in 25% of people, [65] defects of the atrial or ventricular septum, congenital valvular diseases (eg, congenital aortic stenosis) or diseases related to blood vessels or blood flow from the heart (ductus arteriosus). open or aortic contraction).[66][67] These conditions can cause symptoms that vary depending on age. If the deoxygenated blood moves directly from the right side to the left side, the condition can be noticed at birth because it will lead to cyanosis in the baby as in tetralogy of Fallot. Heart problems can affect a child’s ability to grow. [66] Some causes can correct over time and are considered benign. Some causes can be identified incidentally during a cardiac examination. These disorders can be diagnosed with echocardiography. [67]
