About Atrial Septal Defect (ASD) doctors in India
This directory is based on doctors currently listed in GAF Healthcare's registry. Clinical suitability varies by patient; a doctor should review your history and investigations before any treatment decision.
About the Condition
What is Atrial Septal Defect (ASD)?
An atrial septal defect (ASD) is a hole in the wall separating the two upper chambers of the heart, present from birth, that allows blood to flow abnormally between the left and right atria. Small defects may close on their own in early childhood and cause no lasting harm, while larger or unrepaired defects can place chronic strain on the right side of the heart and the pulmonary circulation over time. If left unaddressed, a significant ASD raises the long-term risk of right heart enlargement, atrial arrhythmias, pulmonary hypertension, and, in advanced cases, a reversal of the abnormal blood flow known as Eisenmenger syndrome. Determining how much, if any, intervention is needed depends on the defect's size and location, the degree of haemodynamic impact, and a full clinical assessment of the individual patient.

Treatment options for Atrial Septal Defect (ASD)
Care may include lifestyle changes, medical treatment, specialist review or a procedure, depending on the diagnosis, associated conditions and individual goals. The options below are associated with this condition in the GAF Healthcare directory.
ASD Closure Surgery treats an Atrial Septal Defect, a hole between the heart's upper chambers that allows abnormal blood flow and can strain the heart and lungs over time.
Why it may be consideredIt is performed either by closing the defect with a catheter-delivered device or by surgically patching it during open-heart surgery, depending on the size, location and age of the patient. Timely closure prevents long-term complications such as pulmonary hypertension, arrhythmias and heart failure.
Atrial Septal Defect (ASD) Closure is a procedure performed to seal an abnormal opening between the two upper chambers (atria) of the heart, which if left untreated can cause abnormal blood flow, heart enlargement, and long-term heart or lung complications.
Why it may be consideredIt can be performed either through a minimally invasive catheter-based device or through open-heart surgery, depending on the size, location, and type of the defect. The goal is to restore normal blood circulation and prevent future cardiac strain, especially important in children with congenital heart disease.

Common questions
FAQs about Atrial Septal Defect (ASD) in India
What is Atrial Septal Defect (ASD)?
An atrial septal defect (ASD) is a congenital opening in the interatrial septum — the muscular wall between the heart's two upper chambers — that allows oxygenated and deoxygenated blood to mix. ASDs vary considerably in size, anatomical type (such as secundum, primum, or sinus venosus), and clinical significance.
What are the symptoms and health risks of Atrial Septal Defect (ASD)?
Many children and adults with a small-to-moderate ASD have no obvious symptoms for years, while those with larger defects may experience fatigue, reduced exercise tolerance, frequent respiratory infections, or — in adults — palpitations and shortness of breath reflecting progressive right heart changes. Paradoxical embolism, where a clot passes through the defect and reaches the arterial circulation, is a recognised though less common complication that can present as stroke or TIA. Experiencing any of these symptoms does not confirm an ASD, and symptoms alone are not sufficient to establish a diagnosis or determine treatment.
How is Atrial Septal Defect (ASD) diagnosed?
Diagnosis typically begins with a clinical examination, during which a cardiac murmur or fixed splitting of the second heart sound may be detected, followed by an echocardiogram (transthoracic or, where needed, transoesophageal) to visualise the defect, measure its size, assess the direction and volume of the shunt (commonly expressed as the Qp:Qs ratio), and evaluate right heart dimensions. Additional investigations such as cardiac MRI, chest X-ray, ECG, or cardiac catheterisation may be used to quantify pulmonary pressures and vascular resistance, particularly when pulmonary hypertension is suspected. The overall haemodynamic significance of the defect — not size alone — guides management decisions, and these must be interpreted by a qualified clinician in the context of the individual patient's full clinical picture.
How is Atrial Septal Defect (ASD) treated?
Treatment decisions are guided by defect size, the degree of left-to-right shunting, the presence of symptoms, right heart remodelling, and the patient's age and overall health; not every ASD requires active intervention. For haemodynamically significant defects, closure is generally recommended and can be achieved either by a minimally invasive transcatheter approach — where a closure device is delivered via a catheter through a vein — or by open-heart surgery, with the appropriate method depending on the defect's anatomical type and size. A paediatric or adult congenital cardiologist will determine which approach is most suitable based on a thorough individual assessment.
Can Atrial Septal Defect (ASD) be treated without surgery?
Small ASDs, particularly the secundum type in young children, are often monitored conservatively with regular echocardiographic follow-up, as spontaneous closure can occur in the first few years of life. Where closure is not immediately indicated, or while monitoring is ongoing, a cardiologist may recommend medications to manage associated symptoms such as arrhythmias or, in selected cases, anticoagulation to reduce embolic risk. However, medications do not close the defect itself, and patients with haemodynamically significant ASDs will ultimately be evaluated for a procedural or surgical approach.
When is ASD Closure Surgery considered for Atrial Septal Defect (ASD)?
ASD Closure Surgery may be considered when conservative or medical options have not achieved enough improvement, or when the severity of the condition warrants it. The decision depends on clinical assessment, expected benefits and individual risks.
Which doctor treats Atrial Septal Defect (ASD)?
ASD is typically evaluated and managed by a paediatric cardiologist in children, or by an adult congenital heart disease (ACHD) cardiologist in adolescents and adults; interventional cardiologists and paediatric or congenital cardiac surgeons are involved when a procedural or surgical closure is planned. Close collaboration between these specialists, together with cardiac imaging experts, is standard in centres experienced with congenital heart disease.
How do I choose a doctor for Atrial Septal Defect (ASD)?
When comparing providers, consider the centre's documented experience with both transcatheter and surgical ASD closure, its access to dedicated congenital cardiac imaging and cardiac catheterisation facilities, and the availability of a multidisciplinary congenital heart team that can provide structured long-term follow-up, particularly important given that patients may require monitoring into adulthood.
What documents do international patients need to share for a medical evaluation?
Share a medical summary, investigation and imaging or biopsy reports where relevant, a current medication list, previous diagnoses and related treatment records. Provide clear copies with translation where needed.
How does GAF Healthcare help international patients plan treatment in India?
Our care coordination team helps review initial medical information, connect you with suitable doctors and hospitals, explain next steps and indicative estimates, and organise a treatment plan before travel.
