Endovascular treatment of аtrial septal defect with aortic margin deficiency

Atrial septal defect (ASD) is one of the most common congenital heart defects and accounts for about 7% of all congenital heart abnormalities. It occurs more often in women than men. Until the 90s of the XX century, the main method of surgical treatment of ASD was a plasty or suturing the defect in the open heart with the use of artificial circulation. The main indica- tion for surgical correction of ASD is the presence of a moderate or significant left-right shunt (with a coefficient of pulmonary-systemic blood flow 1.5), in order to prevent the possibility of developing pulmonary hypertension, congestive heart failure, atrial arrhythmia and other complications. Although surgical correction of open heart ASD is now safe, widely used and has a low mortality rate (less than 1%), it can be accompanied by intra- and postoperative complications that may occur even in a longer period. In this work, we present the results and peculiarities of the occluder implantation technique only for the ASD with aortic margin deficiency.
