A hole in the newborn’s heart can be interpreted as a heart murmur heard during the physician’s auscultatory examination, where congenital heart disease or an unclosed foramen ovale is suspected, or after a cardiac ultrasound examination, where a local defect is judged. However, not every newborn will have these abnormalities after birth. Usually, oval foramen insufficiency is more common, but most recover well and can close on their own. If the murmur appears from an atrial septal defect or a ventricular septal defect, it is considered a congenital heart disease, and it is necessary to determine how to deal with it according to the specific situation. However, if the defect is large or the baby has other abnormalities, a cardiac surgeon should be consulted to make a specific assessment of the condition and perform surgical repair when appropriate.
