Implication

Supports MRI feasibility for noninvasive ASD detection; leaves open accuracy and generalizability pending larger prospective validation.

Key Points

The aim was to assess the effectiveness of magnetic resonance imaging in identifying atrial septal defects (ASD) in patients compared to control subjects.
Obtained MRI images from six patients with known or suspected ASD and 33 control subjects without congenital heart disease.
Images were taken along long and short axes of the left ventricle and septum to display anatomic landmarks.
Comparison made against cardiac catheterization and surgical confirmation.
Identified and localized ASDs in all six patients (five secundum, one primum) with confirmation through cardiac catheterization.
Encountered three false positives (9%) in control subjects suggesting apparent ASDs.
Long-axis views effectively displayed the location and diameter of defects, showing good agreement with defect size measurements.

Does magnetic resonance imaging accurately identify and localize interatrial septal defects in patients with known or suspected ASD?

Population

39 subjects, comprising 6 patients with known or suspected interatrial septal defects (ASD) and 33 control subjects without congenital heart disease.

Intervention

Magnetic resonance imaging (MRI) with image planes oriented to the long and short axes of the left ventricle and septum.

Comparator

Cardiac catheterization (n=6) and surgery (n=4) as reference standards.

Outcome

Identification, localization, and measurement of interatrial septal defects.surrogate

MRI is a feasible and accurate non-invasive imaging modality for identifying, localizing, and sizing interatrial septal defects, showing good agreement with catheterization and surgery.
