Abstract：Objective To evaluate the changes of function of right ventricular using echocardiography after transcatheter closure of atrial septal defect(ASD)and to study the feasibility and superiority of echocardiographic evaluation of right ventricular function. Methods In 70 patients with transcatheter closure of ASD,echocardio?graphic examinations were made different time intervals after the closure to calculate right cardiac morpnology and function. Results After closure ASD in different time intervals, the size of RAEDd1, RAEDd2, RVEDd1, RVEDd2, RVEDd3, Inferior Vena Cava and RIMP, RVEF, TAPSE and FAC were obviously decreased(P<0.01)between two groups. All events were obviously decreased compared precious function(P < 0.01)and the interaction of the time (P < 0.01). Conclusion The construction of right ventricular narrows gradually and the function recovers after transcatheter closure of ASD in a year and those who did not become worse.
