What We Do

An atrial septal defect is a hole in the wall that divides between the two upper chambers of the heart. These defects are present from birth. They usually vary in size from a penny to a loonie, and may damage the heart and lungs if left uncorrected.

An ASD Septal Occluders (Amplatzer Septal Occluder) is a double-sided disc that's used as a seal. It is separated by a waist which is sized to your defect. This device is made of surgical grade Dacron and metal alloys. These occluders can be inserted through a tube in the leg and implanted in the heart to close the defect.
