ASD Closure Device treatment India
An atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart. The condition is present from birth (congenital). Smaller atrial septal defects may close on their own during infancy or early childhood.
Large and long-standing atrial septal defects can damage your heart and lungs. An adult who has had an undetected atrial septal defect for decades may have a shortened life span from heart failure or high blood pressure in the lungs. Surgery is usually necessary to repair atrial septal defects to prevent complications...
Symptoms of Atrial Septal Defect (ASD)
Many babies born with atrial septal defects don't have signs or symptoms. In adults, signs or symptoms may not develop until age 30 or later.
Your doctor may first uncover an atrial septal defect during a regular checkup while listening to your heart using a stethoscope. Hearing a heart murmur may signal a hole in your heart. Atrial septal defects are often found when an ultrasound exam of the heart (echocardiogram) is done for another reason.
Signs and symptoms of atrial septal defects develop once damage occurs to the heart and lungs. Infants with larger atrial septal defects may have poor appetites and not grow as they should. Adults and infants may have signs of heart failure or arrhythmias....
Causes of Atrial Septal Defect (ASD)
Doctors know that heart defects present at birth (congenital) arise from errors early in the heart's development, but there's often no clear cause. Genetics and environmental factors may play a role.
An atrial septal defect allows freshly oxygenated blood to flow from the left upper chamber of the heart (left atrium) into the right upper chamber of the heart (right atrium). There it mixes with deoxygenated blood and is pumped to the lungs, even though it's already refreshed with oxygen. If the atrial septal defect is large, this extra blood volume can overfill the lungs and overwork the heart. If not treated, the right side of the heart eventually enlarges and weakens. In some cases, the blood pressure in your lungs increases as well, leading to pulmonary hypertension...
When to seek medical advice for Atrial Septal Defect (ASD)
Contact your doctor if you or your child has any of these signs or symptoms : -
* Poor appetite
* Failure to gain weight (infants)
* Bluish discoloration of the skin
* Shortness of breath
* Easy tiring
* Swelling of legs, feet or abdomen
* Heart palpitations or skipped beats...
These could be indications of heart failure or another complication of an atrial septal defect.
Tests and diagnosis for Atrial Septal Defect (ASD)
He or she may request one or more of the following tests : -
Echocardiogram : - This is the most common test used to diagnose an atrial septal defect. In fact, many atrial septal defects are found during an echocardiogram done for another reason. In echocardiography, sound waves produce a video image of the heart. It allows your doctor to see your heart's chambers and measure their pumping strength. This test also checks heart valves and looks for any signs of heart defects...
Chest X-ray : - An X-ray image helps your doctor see the condition of your heart and lungs. An X-ray may identify conditions other than a heart defect that may explain your signs or symptoms...
Electrocardiogram (ECG) : - This test records the electrical activity of your heart and helps identify heart rhythm problems...
Cardiac catheterization : - In this test, a thin, flexible tube (catheter) is inserted into a blood vessel at the groin or arm and guided to your heart. Through catheterization, doctors can diagnose congenital heart defects, test how well your heart is pumping and check the function of your heart valves. Using catheterization, the blood pressure in your lungs also can be measured. Doctors are investigating catheterization techniques to repair heart defects as well...
