Imaging and Sizing of Atrial Septal Defects by Magnetic Resonance
Why the study?
Does phase-contrast cine MR imaging accurately measure atrial septal defect size compared to surgical templates or balloon sizing in patients with ASDs?
Population
30 patients with atrial septal defects (ASDs), mean age 41 +/- 16 years
Comparison
Phase-contrast cine magnetic resonance imaging… vs Surgical templates or balloon sizing at…

Implication
Cine MR may support noninvasive ASD sizing; leaves open prospective validation before guiding closure decisions.
Structured PICO
Does phase-contrast cine MR imaging accurately measure atrial septal defect size compared to surgical templates or balloon sizing in patients with ASDs?
P
Population
30 patients with atrial septal defects (ASDs), mean age 41 +/- 16 years
I
Intervention
Phase-contrast cine magnetic resonance (MR) imaging and spin-echo MR imaging
C
Comparator
Surgical templates or balloon sizing at catheterization
O
Outcome
Accuracy of atrial septal defect size measurement (major diameter and defect area)surrogate
Phase-contrast cine MR imaging provides accurate noninvasive sizing of atrial septal defects to guide patient selection for percutaneous versus surgical closure, whereas spin-echo MR overestimates defect size.
