Implication

CMR demonstrates high accuracy for ASD detection; leaves open its role versus echocardiography pending prospective validation.

Key Points

This research aims to evaluate the sensitivity and specificity of cardiac magnetic resonance in diagnosing atrial septal defects and anomalous pulmonary venous connections.
Reviewed gated transverse cardiac MR images from 31 patients with atrial septal defect and 33 control subjects.
Panel of cardiac radiologists established ASD presence, type, and confidence levels through consensus.
Sensitivity and specificity analyzed using receiver operating characteristic curves.
97% of atrial septal defects correctly identified with specificity rates of 100% for primum and common atrium types.
Pulmonary veins identified at higher rates than those reported for echocardiography.
All cases of anomalous pulmonary venous connection confirmed by angiography were also demonstrated by MR.
