Abstract:
Objective To investigate the right ventricular morphology and function of patients with atrial septal defects by single beat real-time three-dimensional echocardiography.Methods Thirty-four healthy volunteers and twenty-seven ASD patients were enrolled consecutively as normal controls and the ASD group respectively.Single cardiac cycle real-time three dimensional echocardiography was performed in all to evaluate parameters concerning modality and systolic function of participants' right ventricle.The relationship of indexed right ventricular end diastolic volume (IEDVRV) and end systolic volume(IESVRV)with mean pulmonary arterial pressure measured through cardiac catheter and systolic pulmonary artery pressure calculated though the three tricuspid regurgitation were observed.Results Indexed right ventricular end diastolic volume (IEDVRv),end systolic volume(IESVRV),right ventricular stroke volume (ISVRV) and right ventrieular ejection fraction (RVEF) were greater in the ASD group than in controls (P ＜ 0.05).IEDVRv and IESVRV had positive relation with pulmonary pressure measured by cardiac catheter and systolic pulmonary artery pressure calculated though the three tricuspid regurgitation.Conclusions Single cardiac cycle real-time three dimensional echocardiography has an obvious advantage than normal test in evaluating the change of the right ventricular function and shapes,furthermore,single cardiac cycle real-time three dimensional echocardiography can indirectly determined the pressure of the pulmonary without wound.
