Abstract
Methods A total of 53 consecutive patients who were referred for evaluation of ASD by CMR from 2009-2011 were enrolled in the study. The patients with ASD in the setting of complex congenital heart disease were excluded. All patients were being considered for either percutaneous or surgical closure of ASD. The CMR protocol has been described previously and included standard SSFP (steady state free precision) cines to define the LV morphology and function, phase contrast was used to calculate the shunt fraction and define the ASD morphology, and a high resolution contrast enhanced 3-D MR angiograms were performed to assess pulmonary venous anatomy.
Highlights
The association of partial anomalous pulmonary venous connection (PAPVC) with atrial septal defect (ASD) is known, but its prevalence in adult patients with ASD is not well reported in literature
CMR is recognized as excellent method for shunt quantification and assessment of ASD morphology
There were 45 (85%) patients with secundum ASD, 6 (11%) with primum ASD and 2 (4%) with sinus venosous ASD
Summary
The association of partial anomalous pulmonary venous connection (PAPVC) with atrial septal defect (ASD) is known, but its prevalence in adult patients with ASD is not well reported in literature. CMR is recognized as excellent method for shunt quantification and assessment of ASD morphology
