Key result
3D echocardiography identified ruptured aortic fibrous strands causing prolapse of the co-joined cusp as the mechanism for severe aortic regurgitation following aortic balloon valvuloplasty.
Why the study?
Aortic regurgitation is common after aortic balloon valvuloplasty in children, but rare mechanisms like aortic strands rupture causing cusp prolapse require characterization.

Rupture of fibrous strands can be a rare mechanism of severe aortic regurgitation post-balloon valvuloplasty in children, which can be effectively identified using 3D echocardiography.
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.

Avesani et al. (2023) conducted a case report in Severe aortic regurgitation after aortic balloon valvuloplasty in a bicuspid aortic valve (n=1). 3D echocardiography was evaluated on Identification of the mechanism of severe aortic regurgitation. 3D echocardiography identified ruptured aortic fibrous strands causing prolapse of the co-joined cusp as the mechanism for severe aortic regurgitation following aortic balloon valvuloplasty.
