Background
Atrial Septal Defects (ASD) are a common congenital heart disease, which is a congenital abnormality in which the septum between the left and right atria is underdeveloped, causing abnormal shunting of blood flow in the heart. Atrial septal defects can be divided into two major types, secondary pore type defects and primary pore type defects, and the former are the majority. About 10-15% of the congenital heart disease, and the ratio of male to female is 1: 2.
An Atrial Septal Defect (ASD) occluder is a specially designed instrument for occluding atrial septal defects. The physician will select the appropriate occluder for a particular atrial septal defect and the selected occluder will be implanted through the catheter to the defect site and permanently left at the defect site. The technology is firstly used in clinic in 1976. Until now in the late eighties, with the continuous improvement of occluders, the technology has become mature day by day, especially under the guidance of the rapidly developed two-dimensional and three-dimensional transesophageal echocardiography technology. The therapeutic measures are to adopt a transfemoral femoral vein puncture method, send the stopper into the atrium, fix the stopper at the Atrioventricular Septal Defect (ASD) lesion, block left-right shunt of the atrial level and restore the normal blood circulation path.
Atrial septal defects, however, are prone to endocardial infection, which affects cardiac function. Under the condition, if the problems of obvious pulmonary hypertension and the like do not exist, the defect part is generally only required to be blocked or repaired by interventional therapy, the wound is small, the patient can be discharged after observing for 2 days after the blockage, and the postoperative recovery is quicker. However, if the patient with high pulmonary artery resistance has a right-left shunt due to the combination of the congenital heart disease (such as ASD) and pulmonary hypertension, the traditional ASD occluder cannot completely cure the patient, and the correction of the cardiac deformity cannot reduce the pulmonary artery pressure, and can also cause the pulmonary artery pressure of the patient to rise sharply or even die suddenly.
