heart, section, the middle, heart, atrial septal defect, asd, atrial septal defect, abnormality, the upper chambers, the heart, atria, wall between the right, left atria, does not close completely, defect is present at birth, congenital, atrial septal defect, asd, congenital heart defect, in fetal circulation there, an opening between the two atria, upper chambers, the heart, blood to bypass the lungs, opening, closes, the time the baby is born, asd is persistent, blood continues to flow, left, right atria, a shunt, asd is present in 4 out of 100, 000 people, person has no other congenital defect, symptoms absent, particularly in children, have manifested by age 30, individuals, asd, at an increased risk, developing a number of complications, infective endocarditis, a bacterial infection, the heart, heart failure, an abnormally fast heart rhythm known, atrial fibrillation, frequent respiratory infections in children, difficulty breathing, dyspnea, shortness of breath, sensation of feeling the heart beat, palpitations, small-to moderate-sized defects, no symptoms at, middle age, a palpable pulsation, the pulmonary artery, in the chest, examination, a stethoscope, auscultation, the heart, reveals abnormal heart sounds, a murmur, increased blood flow across the pulmonic valve, signs of heart failure, shunt is large, increased blood flow across the tricuspid valve, between the right atrium, ventricle, an additional murmur, tests, in the diagnosis of asd, a chest x-ray, an echocardiography, ultrasound, the heart, a contrast echocardiography, a color doppler/ study, the heart, transesophageal echocardiography, tee, a cardiac catheterization, a coronary angiography, patients over 35 years old, an mri of chest, an ecg, atrial fibrillation, right atrial enlargement, a pattern of delayed electrical conduction, in the heart, asd, require treatment, few, no symptoms, defect is small, surgical closure, the defect is recommended atrial septal defect is large, symptoms occur, a new procedure has been developed to close the defect, surgery, involves, introduction of a closure device, heart, wires, catheters, a tiny incision is made, in the groin to introduce the catheters, advanced, heart, closure devise, across the asd, defect is closed, procedure is relatively new, not be applicable to all patients, prophylactic, preventive, antibiotics, prior to dental procedures to reduce the risk of developing infective endocarditis, a small-to-moderate atrial septal defect, live a normal life span, larger defects, disability by middle age, increased blood flow, shunting of blood back, pulmonary circulation, pulmonary hypertension, arrhythmias, particularly atrial fibrillation, heart failure, infective endocarditis, symptoms indicating an atrial septal defect develop, no known way, prevent the defect, the complications, prevented, early detection.
