Development of aortic regurgitation (AR) can complicate an isolated perimembranous ventricular septal defect (VSD). The objective of this study was to identify echocardiographic features of perimembranous VSDs associated with AR. Echocardiograms were evaluated for the presence of aortic cusp override, aortic cusp movement abnormality, and presence of color flow mapping across the ventricular septum in a standard, parasternal long-axis view. Echocardiograms of 26 patients with isolated VSDs were included in the study, 13 had AR and 13 had no evidence of AR. Aortic cusp override in the apical 5-chamber and subcostal coronal views were correlated with the presence of AR, with high sensitivity and low specificity. Flow across the septum in the parasternal long-axis view was associated with AR, with moderate sensitivity and specificity. Aortic cusp movement abnormalities had high sensitivity and low specificity. Our data indicate that these findings may identify patients with perimembranous VSD susceptible to AR.
