A hole in the heart, medically known as an atrial septal defect (ASD) or a ventricular septal defect (VSD), refers to a congenital or acquired heart condition affecting the chambers of the heart. While the term "hole in the heart" is commonly used, there are a few other synonyms that can be used to describe this condition. They include "cardiac defect," "heart defect," "septal defect," and "intracardiac shunt." Each of these terms describes a different aspect of the condition but ultimately refers to the same issue within the heart. Regardless of the term used, the condition typically requires medical intervention to prevent further complications and improve quality of life.
