Closure of the ASD can still remodel the right atrium and ventricular, decrease the pulmonary artery pressure, and improve the cardiac function in the elderly patients.
The achievement of permanent transcatheter closure was decided according to the change of the pulmonary arterial pressure, aortic pressure and oxygen saturation.
封堵成功后监测肺动脉压力、主动脉压力和血氧饱和度变化，决定能否行永久封堵。

There was no difference in the incidence of pulmonary complication and mechanical support time in patient with delayed sternal closure and non-delayed sternal closure (P>0.05).
