Key result
Transcatheter ASD closure using the Amplatzer septal occluder assisted by intracardiac echocardiography achieved a 98% cumulative complete occlusion rate at 3 years without complications.

Does transcatheter ASD closure using ICE as the sole imaging tool provide effective occlusion and safety in patients with secundum ASDs?
Intracardiac echocardiography is a safe and effective sole imaging modality for guiding transcatheter ASD closure, achieving high long-term occlusion rates without the need for general anesthesia.
Zanchetta et al. (2004) conducted an observational in Secundum atrial septal defect (n=135). Transcatheter ASD closure using Amplatzer septal occluder and intracardiac echocardiography was evaluated on Cumulative complete occlusion rate at 3 years. Transcatheter ASD closure using the Amplatzer septal occluder assisted by intracardiac echocardiography achieved a 98% cumulative complete occlusion rate at 3 years without complications.
