An atrial septal defect or ASD is a hole in the wall between two upper chambers of your heart atria. The condition is present at birth, it is congenital. Small defects may never cause a problem and may be found incidentally. It is also possible that small atrial septal defect may close on their own during infancy or early childhood.
Large and long standing atrial septal defects however can damage your heart and lungs, it can even shorten a person’s lifespan from heart failure or high blood pressure that affects the arteries in the lungs (Pulmonary Hypertension).
Many babies are born with atrial septal defects that can be associated with signs and symptoms. In adults the signs or symptoms only begin to appear around the age of 30. But there are chances when the symptoms might not even occur until decades later.
When to see a doctor
Contact the doctor if you or your child has any of these following symptoms
Why do heart defects develop?
Heart Defects are present at birth (congenital) arise from errors early in the heart development that can be a reason of errors in the early heart development. There is no often clear cause to it. Genetics and environmental factors play an important role.
How the heart works with an atrial septal defect?
An atrial septal defect allows freshly oxygenated blood to flow from the left upper chamber of the heart to the right upper chamber. There it is mixed with the deoxygenated blood and pumps it into the lungs even though it is already refreshed with oxygen.
In the condition that atrial septal defect is large, the extra blood volume can overfill the lungs and increase the workload on the right side of the heart. If not treated the right side of the heart eventually enlarges and weakens causing increase blood pressure in the lungs and eventually become a cause of hypertension.
Types of Atrial Septal Defect
How can it be treated with Minimally Invasive Heart Surgery or Keyhole Surgery?
This is one of the new techniques of surgically treating the condition of hole in the heart of a patient. All the above mentioned for atrial septal defects can be treated by Minimally Invasive Atrial Septal Defect Surgery.
