Key result
Transcatheter closure of atrial septal defects without fluoroscopy yielded similar procedure times to the conventional procedure (88 vs 100 minutes; P=0.09) but required higher propofol doses.

Demonstrates feasibility of fluoroscopy-free echo-guided ASD/PFO closure; leaves open whether this approach warrants routine adoption without larger trials.
Cohort (n=153)
Does transcatheter closure under echocardiographic guidance without fluoroscopy maintain procedural efficiency compared to conventional fluoroscopic procedures in patients with atrial septal defects or patent foramen ovale?
Absolute Event Rate: 88% vs 100%
p-value: p=0.09
Transcatheter closure of atrial septal defects and patent foramen ovale can be safely performed without fluoroscopy using echocardiographic guidance, yielding similar procedure times but requiring higher sedation doses.
Ewert et al. (2000) conducted a cohort in Atrial septal defects or patent foramen ovale (n=153). Transcatheter closure under echocardiographic guidance without fluoroscopy vs. Conventional procedure (with fluoroscopy) was evaluated on Procedure times (minutes) (p=0.09). Transcatheter closure of atrial septal defects without fluoroscopy yielded similar procedure times to the conventional procedure (88 vs 100 minutes; P=0.09) but required higher propofol doses.
