Ghazi Farhan Haji, Venus Abdulwahid Alwan, Sa`ad Hashim Mohammed.

Abstract
Background: The atrial septal defect is a common congenital heart disease. Speckle tracking echocardiography is non-invasive diagnostic technique used in assessment of myocardial function.

Aim of study: Evaluate the feasibility and reproducibility of the right ventricle two dimension strain assessed by speckle tracking in patient undergoing atrial septal defect transcatheter occlusion compared with conventional markers before and after transcatheter occlusion.

Patients and methods: A prospective follow-up study, conducted in Ibn-Al-Bitar specialized for cardiac surgery in Baghdad during the period from July 2017 to June 2018, on sample of 30 patient with atrial septal defect and sample of 30 healthy controls. All patients were investigated with echocardiography and speckle tracking one month before transcatheter occlusion, and one month after transcatheter occlusion.

Results: Post transcatheter occlusion, there was a significant decrease in mean right ventricle end diastolic dimension (p< 0.001) and a significant decrease in mean of tricuspid annular plane systolic excursion (p

Key words: atrial septal defect, speckle tracking defect, right ventricle function
