CMR for the evaluation of ASD

A slightly older article in Radiology, in 2003, by Beerbaum P et al from Germany describes the use of CMR, mainly phase-contrast imaging, in the evaluation of ASDs.

Many patients with ASD now undergo transcatheter balloon closure and it is necessary to get adequate information about the size of the ASD, the rim and the distance of the rim from the SVC, coronary sinus, aortic root and AV valves prior to planning treatment.

Traditionally, trans-esophageal echocardiography (TEE) has been the mainstay of diagnosis and evaluation. CMR however is as good and can therefore be used in equivocal cases or in situations where the patient does not want a TEE.
