What is the normal size of ASD?

ASDs were classified by size. Small defects had a maximal diameter > 3 mm to < 6 mm, moderate defects measured ≥ 6 mm to < 12 mm and large defects were ≥ 12 mm.

What size ASD requires surgery?

Larger ASDs (8 to 10 mm), often do not close and may need a procedure. Important factors include the size of the defect, the amount of extra blood flowing through the opening, the size of the right side of the heart, and whether the person has any symptoms.

What is considered a large ASD?

If your ASD is larger than 2 cm, you have a greater risk of problems such as: Right heart enlargement, which leads to heart failure. Abnormal heart rhythms, including atrial fibrillation or atrial flutter, affect 50 to 60 percent of all patients over 40 with an ASD. Stroke.

How serious is ASD?

A large, long-standing atrial septal defect can damage your heart and lungs. Surgery or device closure might be necessary to repair atrial septal defects to prevent complications.

When should an ASD be closed?

ASD closure is indicated in the presence of a significant left-to-right shunt, defined by a significant right heart enlargement due to volume overload, regardless of symptoms (3,4).

Does ASD close by itself?

The most common type of ASD may close on its own as your child grows. Once an ASD is diagnosed, your child’s cardiologist will check your child to see if the defect is closing on its own. An ASD will usually be fixed if it has not closed by the time a child starts school.

Is ASD considered a disability?

Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication and behavioral challenges.

What happens if ASD is not treated?

A large atrial septal defect can cause extra blood to overfill the lungs and overwork the right side of the heart. If not treated, the right side of the heart eventually enlarges and weakens. The blood pressure in your lungs can also increase, leading to pulmonary hypertension.

How is ASD surgery done?

Robotically-assisted atrial septal defect (ASD) and patent foramen ovale (PFO) repair surgeries are performed through small incisions made in the right sight of the chest.

How is an Amplatzer used to treat an ASD?

The procedure involves making a small incision, typically in the groin, and inserting a small tube, called a catheter or sheath, to navigate through the blood vessels to the procedure site within the heart. In patients with an ASD, the doctor guides the device through the catheter or sheath and deploys it in the ASD to seal the hole.

What are the dimensions of the Amplatzer Septal Occluder?

The Amplatzer TM Septal Occluder has a wide connecting waist that centers the device and fills the ASD. This occluder—offering the widest range of ASD sizes—can treat defects from 3 mm to 38 mm.

How big does an Amplatzer balloon need to be?

Patients with a retro-aortic rim of less than 5 mm in any echocardiographic plane, or patients in whom the device physically impinges on (i.e. indents or distorts) the aortic root, may be at increased risk of erosion. Do not select a device size greater than 1.5 times the echocardiographic-derived ASD diameter prior to balloon sizing.

What is the temperature rise of an Amplatzer?

In this testing, the device produced a temperature rise of 1.1°C at 1.5 tesla and 1.6°C at 5.0 tesla. MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the device.
