Is ASD Treatable with Medication?

An atrial septal defect is a congenital heart defect that is often treatable with medications but it will also depend on the severity of the case. 

What is ASD?

A wall called the septum divides the left and right sides of the heart. ASD is a gap or defect in the septum, which separates the top two chambers of the heart.

Due to this defect, blood that is oxygen-rich can leak into the heart's blood chambers that are oxygen-poor. 

Cardiologists frequently recommend surgery to treat a medium- to a large-sized atrial septal defect found in childhood or adulthood in order to avoid further complications.

There are currently no known treatments for ASD. The signs and symptoms of an atrial septal defect can be lessened with medication, but the defect cannot be repaired. Large ASDs measuring 8 to 10 mm frequently require surgery because they do not close naturally. When a child reaches the age of 3-5 years, ASD defects are to be closed surgically.

Causes 

A normal fetal opening, which every child has at birth, is located between the upper heart chambers and allows blood to divert away from the lungs prior to birth. 

The opening is no longer required after birth and typically closes or gets very small within a few weeks or months. The opening may occasionally be larger than usual and not close completely after birth. In the majority of kids, the cause is unknown. 

Effects of ASD on the Heart

Blood can cross the hole from the left upper heart chamber (left atrium) to the right upper chamber (right atrium) and out into the lung arteries in a child with ASD.

The heart and lungs must work harder to compensate for the extra blood being pumped into the lung arteries when the ASD is large, and the lung arteries may gradually deteriorate.

Types of ASD

There are 3 common types of ASD;

• Ostium Secundum
• Ostium Primum
• Sinus Venosus
• Coronary Sinus

Symptoms of ASD

• The abnormal splitting of the second heart sound causes a murmur.
• Abnormal cardiac impulse 
• Irregular or rapid heart rhythm
• Cyanosis
• Shortness of breath with or without exertion
• Cough 
• Dizziness
• Fainting
• Fatigue
• Swelling of hands, face, or legs

Tests/Diagnosis of ASD

When an ASD is suspected, the following diagnostic tests are advised;

• Echocardiography (Transthoracic/transoesophageal/intracardiac)
• Angiography 
• Magnetic Resonance Imaging (MRI)

ASD Treatment

If a child is found to have an atrial septal defect, the doctor may want to keep an eye on it for a while to see if the hole closes naturally. They may prescribe medication to treat symptoms during this time.

Medication for ASD typically includes beta-blockers, ACE inhibitors, and anticoagulants, which help reduce the risk of stroke and other heart-related complications.

Even if there aren't many symptoms, a doctor may advise closing an atrial septal defect in a child who has a large one in order to prevent problems in the future.

Cardiac catheterization or open heart surgery may help to close the hole:

• Catheter-based repair: Using imaging methods, a thin, flexible tube (catheter) is inserted into a blood vessel, typically in the groin, and directed to the heart. The hole is sealed by inserting a mesh patch or plug through the catheter. Heart tissue forms a seal all the way around it, sealing the hole for good. Only atrial septal defects of the secundum type are repaired using catheters. However, open heart surgery may be necessary for some large secundum atrial septal defects.
• Open-heart surgery: An incision through the chest wall is made in order to directly access the heart during this kind of atrial septal defect repair surgery. To close the hole, the surgeons use patches. Primum, sinus venosus and coronary sinus atrial defects can only be corrected through this open-heart surgery.

Robot-assisted heart surgery and minimally invasive surgery can both be used to repair atrial septal defects in some cases.

Conclusion

Lifestyle changes such as a low-salt diet and regular exercise can help protect the heart and reduce the risk of complications. Ultimately, the type of medication used to treat ASD varies depending on the severity of the defect and the patient's medical history. If the condition is serious, you need to admit the patient to the best heart surgery hospitals in India so that they can recover quickly.
