Abstract

Objective To evaluate the value of intracardiac echocardiography (ICE) on measurement atrial septal defects (ASD) and guidance of transcatheter closure of ASD. Methods Nine patients [4 males and 5 females, mean age (11.0± 17.1 ) years, mean weight (30±18.3) kg] with secundum ASD underwent Amplatzer transcatheter device closure guided by ICE with HP 5500 color Doppler systems. Results All patients had successful device placement and complete closure immediately without residual shunt and complications. During the occlusion operation, ICE correlated better for measurement of ASD with the balloon stretched diameter than transthoracic echocardiography (TTE) before operation. Conclusion ICE is a feasible and effective method in guidance of transcatheter closure of ASD.
