A hole in the heart, medically termed a septal defect, is a congenital condition characterized by an opening in the heart's septum, the wall separating its chambers. The two primary types are Atrial Septal Defect (ASD), located between the upper chambers, and Ventricular Septal Defect (VSD), situated between the lower chambers. Small septal defects often close spontaneously during infancy and may not require treatment. However, larger defects can lead to complications such as fatigue, shortness of breath, irregular heart rhythms, and an increased risk of stroke. Diagnosis typically involves imaging techniques like echocardiograms to assess the size and impact of the defect. Treatment options vary based on the defect's size and severity. Catheter-based procedures offer a minimally invasive method to close certain types of defects, particularly secundum ASDs . In cases where catheter-based closure isn't feasible, open-heart surgery may be necessary to repair the defect . Post-treatment, patients require regular follow-ups to monitor heart function and ensure the defect remains closed. With timely and appropriate intervention, individuals with septal defects can lead healthy, normal lives.
