's general knowledge of atrial septal defect of department of cardiovascular surgery of the chest
Atrial septal defect means a primitive heart insula of embryo and becomes abnormal while taking place, absorbing and merging, still remain the room hole not closed between the left and right atrium, cause the distributary of the blood flow. The room is scarce can exist alone, can also exist with the deformity of other cardiovascular vessels. Embryo's development of the inborn atrial septal defect foundation can be divided into and continued and taken place the pass and sent the big class of pass defect two originally, refered room lack, mean, continue, it sends holes to be most common for continue, send hole room scarce at the clinical scarce room promptly usually, accounting for 23% of congenital heart disease, women exceed men. Symptom and the intersection of condition and development of disease this depend on flawed or damaged size, defect can have no symptom for a long time while being little, defect is great symptom appears early, and develop into the artery high pressure of lung progressively.

Since the childhood apt to suffer from upper airway infection, youth the symptom aggravates, feel palpitation often behind one, paroxysmal tachycardia, the amount of exercise is limited, can present the artery high pressure and in heart failure of lung finally, it is apt to present cyanosis.
The intersection of surgery and treatment, should perform the operation as soon as possible while being getting clear diagnosing, 5 about year old ideal time; Persons who are still shunted right with the left of high pressure of lung artery should strive for the operation; Severe the intersection of lung and artery high pressure, present the persons who are shunted left of right, should be regarded as operation taboo disease. The operation prognosis is generally good.
This disease is inborn deformity, the treatment of internal medicine department can't effect a radical cure, the room lacks and mends the mortality of skill very low, the curative effect of operation is precise, the postoperative heart functions can all be improved or totally returned to normal. But curative effect relatively bad in high pressure in artery with serious lung, resume slow while being postoperative, even lose the chance of the operation while being getting severe while being specific. Should be early surgery.
