What size is considered a large ASD?

What size is considered a large 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 is the size of small VSD?

The VSDs were classified as: small (diameter less than or equal to 3 mm), medium (3 to 6 mm) and large (greater than 6 mm).

Do ASD need to be closed?

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.

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 big is a septal occluder for ASD closure?

Are there any approved devices to close ASDs?

There are two devices approved by the US Food and Drug Administration (FDA) to close ASDs—the Amplatzer septal occluder (St. Jude Medical, Inc., St. Paul, MN), which has been approved for more than 10 years, and the Helex septal occluder (Gore & Associates, Flagstaff, AZ), which has been approved for approximately 7 years in the United States.

How big should a septal closure device be?

In self-centering devices such as the Amplatzer Septal Occluder (ASO) (St. Jude Medical, St. Paul, MN, USA), the recommended device size is the same or slightly larger (<2 mm) than the SFD.

Which is the best transcatheter device closure of ASD?

Trans-catheter device closure of ASD (TC-ASD) has well-established efficacy and safety. For most individual patients with suitable anatomy, TC-ASD is the preferred method for treating ASD. The availability of large multicenter datasets has made it possible to study practice patterns at a range of hospitals across the United States.
