Heart septal defects refer to abnormalities in the septum, the wall that separates the chambers of the heart. The heart comprises four chambers, consisting of two atria (upper chambers) and two ventricles (lower chambers).. In some cases, there can be openings or holes in the septum, leading to a condition known as a septal defect. There are two main types of heart septal defects: atrial septal defects (ASD) and ventricular septal defects (VSD). ASD occurs when there is a hole between the atria, allowing blood to flow between them. VSD, on the other hand, involves a hole in the septum between the ventricles, allowing blood to pass from the left to the right side of the heart. These defects can disrupt the normal blood flow, causing various symptoms such as fatigue, shortness of breath, and, in severe cases, heart failure. Treatment options vary depending on the size and location of the defect, ranging from medications to surgical interventions. Early detection and appropriate management are crucial for improving outcomes in individuals with heart septal defects. Regular medical check-ups and diagnostic tests can aid in the timely identification and intervention for this condition.
