“…The current study showed a significant association between primum ASD type with each of large ASD with posteroinferior deficient rims, large ASD diameter, and large IAS. This finding is in agreement with the results of the Song study in South Korea (30), which stated that on echocardiography, the primum ASD is characterized by large ASD with deficient rims and large IAS. The mean ASD diameter was 19.7 mm.…”

An atrial septal defect (ASD), sometimes called a hole in the heart is a type of congenital heart defect in which there is an abnormal opening in the dividing wall between the upper filling chambers of the heart (the atria). To determine the outcome of surgical closure in patients with atrial septal defects, we designed a retrospective study, including 120 patients present with an atrial septal defect after surgical closure done in the cardiac teaching center in Sulaimani city. The data collected include the patients that admitted which are known cases of ASD and treated by open heart surgery during the last nine years from 1st of January 2008 until the 1st of January 2018. A total of 120 children diagnosed with Atrial Septal Defect (ASD) were included in this study with a mean age of 7.8±4.4 years; 32.5% of them were 1-5 years old, 50.8% of them were in the age group 6-12 years, and 16.7% of them were in the age group 13-19 years. Only three ASD children received medical treatment while all of them were treated surgically with open-heart surgery. The mean age of ASD children at surgery was7.8±4.4 years; 5.8% of them were 1-2 years old, 28.4% of them were 3-5 years old, 49.1% of them were in the age group 6-12 years, and 16.7% of them were in the age group 13-19 years. There was a significant association between primum ASD type and large ASD with posteroinferior deficient rims (P=0.04). A significant association was observed between primum ASD type and large IAS (P=0.006). Mean ASD diameter was significantly higher among patients with primum ASD type (P=0.01). The outcome of surgical closure of the atrial septal defect in children is effective and safe. Ventricular arrhythmia in the form of ectopic was the postoperative complication in one patient. The main echocardiography findings of children with atrial septal defects were large ASD with posteroinferior deficient rims.

The dynamic characteristics of the area of the atrial septal defect (ASD) were evaluated using the technique of real-time three-dimensional echocardiography (RT 3DE), the potential factors responsible for the dynamic characteristics of the area of ASD were observed, and the overall and local volume and functions of the patients with ASD were measured. RT 3DE was performed on the 27 normal controls and 28 patients with ASD. Based on the three-dimensional data workstations, the area of ASD was measured at P wave vertex, R wave vertex, T wave starting point, and T wave terminal point and in the T-P section. The right atrial volume in the same time phase of the cardiac cycle and the motion displacement distance of the tricuspid annulus in the corresponding period were measured. The measured value of the area of ASD was analyzed. The changes in the right atrial volume and the motion displacement distance of the tricuspid annulus in the normal control group and the ASD group were compared. The right ventricular ejection fractions in the normal control group and the ASD group were compared using the RT 3DE long-axis eight-plane (LA 8-plane) method. Real-time three-dimensional volume imaging was performed in the normal control group and ASD group (n=30). The right ventricular inflow tract, outflow tract, cardiac apex muscular trabecula dilatation, end-systolic volume, overall dilatation, end-systolic volume, and appropriate local and overall ejection fractions in both two groups were measured with the four-dimensional right ventricular quantitative analysis method (4D RVQ) and compared. The overall right ventricular volume and the ejection fraction measured by the LA 8-plane method and 4D RVQ were subjected to a related analysis. Dynamic changes occurred to the area of ASD in the cardiac cycle. The rules for dynamic changes in the area of ASD and the rules for changes in the right atrial volume in the cardiac cycle were consistent. The maximum value of the changes in the right atrial volume occurred in the end-systolic period when the peak of the curve appeared. The minimum value of the changes occurred in the end-systolic period and was located at the lowest point of the volume variation curve. The area variation curve for ASD and the motion variation curve for the tricuspid annulus in the cardiac cycle were the same. The displacement of the tricuspid annulus exhibited directionality. The measured values of the area of ASD at P wave vertex, R wave vertex, T wave starting point, T wave terminal point and in the T-P section were properly correlated with the right atrial volume (P<0.001). The area of ASD and the motion displacement distance of the tricuspid annulus were negatively correlated (P<0.05). The right atrial volumes in the ASD group in the cardiac cycle in various time phases increased significantly as compared with those in the normal control group (P=0.0001). The motion displacement distance of the tricuspid annulus decreased significantly in the ASD group as compared with that in the normal control group (P=0....
