ASD Closure Surgery is performed to treat Atrial Septal Defect, a congenital heart condition characterized by an abnormal opening between the upper chambers of the heart. If left untreated, ASD can cause abnormal blood flow, breathlessness, fatigue, irregular heartbeat, and increased strain on the heart and lungs. This procedure safely closes the defect and restores normal circulation, improving overall heart function and long-term cardiovascular health. Advanced surgical techniques and minimally invasive approaches may be used depending on the patient’s condition. ASD closure is commonly performed in both children and adults after detailed cardiac evaluation.
