چکیده مقاله:

Background: One of the inclusion criteria for applying atrial septal defect (ASD) closing procedure is an increased pulmonary-tosystemicblood flow ratio (Qp/Qs). Eccentricity index (EI) is associated with ventricular dysfunction in patients with pulmonaryhypertension.Objectives: As ASD patients have overload volume and pressure in their pulmonary arteries, we tried to test this hypothesis if EI andQp/Qs ratio are possibly associated.Patients and Methods: This study is a correlation study. 64 patients with primary diagnosis of secundum type ASD enrolled in thisstudy and echocardiography was performed for all of them. Data were analyzed by SPSS as well as descriptive and statistical tests.Results: Bivariate correlation test showed that there was a positive and significant association between Qp/Qs ratio and EI (r = 0.502,P = 0.001). Linear regression analysis showed that there was a linear association between Qp/Qs ratio and EI (Beta = 1.765, P = 0.001).Conclusions: We found that EI and Qp/Qs ratio are significantly and positively associated and Qp/Qs ratio can be easily estimatedby measuring EI in secundum type ASD patients.
