Contact UsAn Atrial Septal Defect (ASD), often referred to as a ‘heart hole’, is a common congenital heart defect. While some small ASDs may close on their own, many require intervention to prevent long-term complications. Traditionally, this involved open-heart surgery. However, advancements in medical technology have introduced the less invasive procedure involving an ASD closure device that offers a safer and quicker path to recovery for many patients.
What is Atrial Septal Defect (ASD)?
An Atrial Septal Defect is a hole in the septum, the wall that separates the heart's upper two chambers (atria). This hole allows oxygen-rich blood from the left atrium to mix with oxygen-poor blood in the right atrium, leading to an overload of blood flowing to the lungs. Over time, this extra blood flow can strain the heart and lungs, potentially causing serious issues like pulmonary hypertension, heart failure, or stroke.
Early diagnosis and timely intervention are crucial. While some ASDs might be asymptomatic in childhood, symptoms like shortness of breath, fatigue, heart palpitations, and recurrent respiratory infections often emerge in adulthood. Identifying and treating these defects can significantly improve quality of life and prevent severe complications.
The ASD Device Closure Procedure
The ASD device closure procedure is a minimally invasive technique used to close most types of ASDs without the need for open-heart surgery. This innovative approach is a preferred option for many patients due to its numerous benefits. Studies show the ASD device closure procedure has an impressive success rate of over 95%, with excellent long-term outcomes for patients of all ages. This makes it a highly effective and safe option for congenital heart defect treatment.
How does it work?
The ASD device closure procedure steps involve:
-
A thin, flexible tube called a catheter is inserted into a blood vessel, usually in the groin.
-
Guided by advanced imaging techniques, the catheter is carefully threaded up to the heart.
-
A specialized closure device, typically made of nitinol mesh, is deployed through the catheter to effectively seal the hole in the atrial septum.
-
Once in place, the device remains permanently to close the ASD, allowing heart tissue to grow over it.
What are the benefits?
The benefits of this procedure includes:
-
Minimally invasive- No large surgical incision, resulting in smaller scars and less pain.
-
Faster recovery- Patients often return to normal activities within a week, significantly quicker than open-heart surgery recovery.
-
Reduced hospital stay- Typically, patients stay for only 1-2 days.
-
Lower risk of complications- Generally associated with fewer risks compared to traditional surgery.
Who is a candidate for ASD Device Closure?
Not all ASDs are suitable for device closure. Candidates are usually those with secundum ASDs that are of an appropriate size and have sufficient surrounding tissue for the device to attach securely.
Expert cardiologist conduct a thorough evaluation to determine if this procedure is the right choice for you or your loved one. This evaluation involves:
-
Echocardiogram (transthoracic and/or transesophageal) to assess the size, location, and edges of the ASD.
-
Electrocardiogram (ECG) and Chest X-ray to evaluate heart function and lung health.
-
Consultation with the team of specialists.
Care essentials
|
Do’s |
Don’ts |
|
Follow medication schedule- Take prescribed medications, especially blood thinners, exactly as directed by your doctor. |
Avoid strenuous activities- Refrain from heavy lifting or vigorous exercise for the first few weeks or as advised. |
|
Attend follow-up appointments- Regular check-ups are vital to monitor your heart and the device's position. |
Do not submerge incision- Avoid baths, hot tubs, or swimming until the incision is fully healed. Showers are generally permitted. |
|
Maintain good hygiene- Keep the incision site clean and dry to prevent infection. |
Do not miss medications- Discontinuing blood thinners prematurely can lead to serious complications. |
|
Gradually resume activities- Start with light activities and slowly increase intensity as advised by your medical team. Most patients return to normal activities within a week. |
Avoid alcohol and smoking- These can impede healing and overall cardiovascular health. |
|
Report any concerns- Immediately contact your doctor if you experience fever, redness/swelling at the groin site, chest pain, or shortness of breath. |
Do not ignore symptoms- Any new or worsening symptoms should be reported promptly. |

Frequently Asked Questions
The procedure is performed under local anaesthesia (general anaesthesia is used in special cases and for babies), so you will not feel any pain during the process. Possible mild discomfort at the groin incision site, after the procedure, can be managed with pain medication.
Typically, follow-up appointments with your cardiologist are scheduled at 1 month, 6 months, and 1 year after the procedure, and then annually thereafter. These visits usually include an echocardiogram to ensure the device is securely in place and the ASD remains closed.
Most patients are prescribed blood thinners for a period of 1 to 6 months post-procedure to prevent clots from forming on the device while tissue grows over it. Your cardiologist will provide specific instructions based on your individual needs.
You will have some restrictions on physical activity, especially strenuous exercise and heavy lifting, for a few weeks. Your doctor will provide a detailed list of activities to avoid and when you can safely resume normal routines. Most patients can resume light activities within a week.
While generally safe, like any medical procedure, there are potential risks, including bleeding, infection, device embolization (device moving from its intended position), allergic reaction to contrast dye, or rarely, perforation of heart structures. Your cardiologist will discuss all potential risks and benefits with you.
