Pattern of pulmonary venous flow in patients with ostium secundum atrial septal defect.

Aims: The purpose of this study is to determine the possible influence of a left to right atrial shunt over the pulmonary venous flow pattern in children with ostium secundum atrial septal defect (ASD).

Methods And Results: Complete two-dimensional, spectral Doppler and colour flow Doppler examination were undertaken to examine the pulmonary vein flow pattern in 74 patients with ASD. This group was compared with a control group of 49 non-cardiological patients of similar ages and gender.

[Echocardiographic Doppler evaluation of ventricular function in children with an atrial septal defect].

Introduction And Objectives: To evaluate ventricular function using Doppler echocardiography in patients with an atrial septal defect (ASD).

Methods: The study involved 158 children, who were divided into two groups: Group 1 comprised 111 children with an ASD, and Group 2, 47 healthy children. Left ventricular systolic function was evaluated by measuring the ejection fraction, the shortening fraction, and the systolic mitral annular velocity (by tissue Doppler), and right ventricular systolic function, by measuring the systolic tricuspid annular velocity.
