Secundum Atrial Septal Defect

Septal defects ( ASD, VSD, Atrioventricular defects) account for 35-40 % of the congenital heart defects. Atrial septal defect ( ASD) is the most common congenital heart anomaly. The incidence of ASD is 1 per 1500 live births or 6-11 % of congenital cardiopathies. It is more common in the females with a female-to-male ratio 2/1. (1) The atrial septal defect is a communication in the interatrial septum that allows blood to flow between the upper chambers of the heart. The many types of atrial septal defect are differentiated from each other by location of the defect in the septum ostium secundum, ostium primum, foramen ovale, common (single) atrium and the sinus venosus defect of the right atrium. (2) The aim of the study is to compare datas such as right heart enlargement, pulmonary hyperflow persistence, rhythm disturbances and FS values in pre and post operatory patients diagnosed with DIA OS. This is a prospective study performed in the General Pediatric Service, the Department of Cardiology for the period 2010-2014. only 12 % of cases had an enlargement of right cavities one month after correcting the defect. Results All cases had no pulmonary hyperflow after correction, and only 16 % of cases had systolic murmur one month after the defect correction. Conclusion By comparing all the variables, we conclude that all the estimated parameters (enlargement of right cavities, pulmonary hyperflow, FS contractility) are significantly improved after the intervention.
