Abstract:
Objective: To explore the effect of three-dimensional echocardiography (RT-3DE) for evaluating right atrial function in patients after atrial septal defect (ASD) closure.
Methods: Our research included 2 group: ASD group,n=50 patients with successful ASD closure and Control group, n=30 normal subjects from physical examination. RT-3DE was conducted at pre-operation and at 3 days, 1 month, 3 months post-operation; the volume of right atrium before contraction (Vpre), minimum volume of the right atrium (Vmin), maximum volume of the right atrium (Vmax), total emptying volume of right atrium (Vt), total emptying volume fraction of right atrium (Ft), active emptying volume fraction (Fa) and passive emptying volume fraction (Fp) were measured and compared between 2 groups at pre- and post-operation respectively.
Results: At pre-operation, compared with Control group, ASD group had increased Vmax, Vmin, Vpre, Vt, and Fa, while decreased Ft and Fp, allP<0.05. At 3 days post-operation, compared with Control group, ASD group had increased Vmax, Vmin, Vpre, Vt, and Fa, while decreased Ft and Fp, allP<0.05. Compared with pre-operation, ASD group had decreased post-operative Vmax, Vmin, Vpre, Vt and Fa while increased Ft and Fp at 3 time points, allP<0.05. At 3 months post-operation, the above 7 indexes were similar between ADS group and Control group,P>0.05.
Conclusion: ADS patients had abnormal volume and function in right atrium, the abnormalities could be improved at 3 days after ASD closure and could be recovered to normal level at 3 months after operation. RT-3DE has the important role for evaluating right atrial volume and function in patients after ASD closure.
