Atrial septal defect is a malformation of the heart, upper chambers (atria) where the wall between the right and left atrium does not close completely. In general, the absence of a hole in the wall (septum) between the two upper heart chambers (the atria). Arial septal defects occur in 4 percent to 10 percent of all children born with congenital heart defects. As a group, atrial septal defects in a child are detected per 1500 live births. Smaller atrial septal defects may close during infancy or early childhood. The health effects of holes that remain open often do not show until the last few years – usually 40 years. Many people do not realize they have a septal far. Sometimes a doctor detects an atrial septal defect during a newborn exam or during a routine examination later in life. Large and long atrial septal defects can damage the heart and lungs. One who can septal undetected for decades have a shortened life of heart failure or high blood pressure in the lungs. In children with ASD very low, the ASD closes on its own about 90% of the time. However, most of the other PDDs are closed. People with certain types of heart defects, including some rarer forms of ASD are at greater risk for developing bacterial endocarditis, an infection of the inner surface of the heart.
The term “septal” refers generally to holes in the atria, resulting from a lack of atrial septal tissue, rather than in connection with a disease called patent foramen ovale (PFO). Symptoms usually manifest at the age of 30. Infants with atrial septal defect may have more appetite and do not develop as they should. Infants may be signs of heart failure or heart rhythm disturbances. Congenital heart defects seem to occur in the family and sometimes with other genetic problems like Down syndrome. A genetic counselor can predict the approximate probability that children will have a future. An atrial septal defect allows oxygen-rich (red) blood from the left atrium through the hole in the wall, then pass with oxygen-poor (blue) blood in the right atrium. The complete closure is in most individuals. In 25-30% of the normal heart, but a probe from the right atrium to left atrium through the foramen ovale be passed and ostium secundum.
The person can also develop, get heart or blood vessel damage and increased risk of having a stroke or heart infection. The significance of congenital heart defects occur in about 8 in 1,000 live births. Surgical closure of the lesion is recommended if the atrial septal defect is large or if symptoms occur. Anticoagulants, often called blood thinners, can help increase the chances of developing a blood clot and a stroke. Anticoagulants include warfarin (Coumadin) and anti-platelet drugs such as aspirin. Keep the heartbeat regular. Examples include beta-blockers (LOPRESSOR, Inderal) and digoxin (Lanoxin). Prophylactic (preventive) antibiotics should be given before dental procedures to reduce the risk of developing infective endocarditis. Embolization (movement of thrombi) normally go to the lungs and cause a pulmonary embolism. In people with ASD, these emboli potentially enter the arterial system. In most cases, atrial septal defects can be prevented. Consider talking with a genetic counselor before they become pregnant.
The treatment of atrial septal defect Reviews
1st Surgical closure of ASD involves opening of at least one atrium and closing the defect with a patch under direct vision.
2nd Embolization (movement of thrombi) normally go to the lungs and cause a pulmonary embolism.
3rd Keep the heartbeat regular. Examples include beta-blockers (LOPRESSOR, Inderal) and digoxin (Lanoxin).
4th Increase the strength of heart contractions. Examples include digoxin (Lanoxin) are.
5th Decrease in the amount of fluid in circulation. This reduces the amount of blood pumping. These drugs, called diuretics, including furosemide (Lasix).
6.Prophylactic (preventive) antibiotics should be given before dental procedures to reduce the risk of developing infective endocarditis.
