Atrial Septal Defect Closure (ASD)
What are the complications caused by atrial septal defect?
In a person with an atrial septal defect blood flows through the hole primarily from the left chamber to the right chamber, which increases the blood volume in the right atrium, in turn resulting in more blood flow through the lungs. If left untreated, this may cause problems in adulthood such as
- pulmonary hypertension – high blood pressure in the lungs
- congestive heart failure – weakening of the heart muscle
- atrial arrhythmias – are abnormal rhythms or beating of the heart
- an increased risk of stroke
