Unusual case of severe aortic regurgitation in a child with bicuspid aortic valve.

ABSTRACT

Aortic regurgitation (AR) is common after aortic balloon valvuloplasty in children and it has been associated with large balloon/annulus ratio, abnormal valve morphology and aortic valve prolapse. We present a rare case of severe AR after aortic balloon valvuloplasty due to aortic strands rupture, causing prolapse of the co-joined cusp.  These findings were identified by 3D echocardiography, highlighting the importance of this imaging technique even in pediatric patients.
