Why the study?
Supravalvular aortic stenosis is a rare left ventricular outflow tract obstruction often accompanied by other cardiac conditions, for which a standard surgical reparative technique has not been established.
Does partial Brom's technique with autologous pericardial patches successfully repair supravalvular aortic stenosis in a pediatric patient with a bicuspid aortic valve?

Partial Brom's technique using autologous pericardial patches successfully repaired supravalvular aortic stenosis and preserved valve function in a pediatric patient with a bicuspid aortic valve.
BACKGROUND: Supravalvular aortic stenosis (SVAS) is a relatively rare form of left ventricular outflow tract obstruction, often accompanied by other cardiac conditions. However, a standard surgical reparative technique has not been established and repairing SVAS remains challenging. CASE PRESENTATION: We repaired SVAS of a 3-year-old boy accompanied by a bicuspid aortic valve and malpositioned coronary orifices by partial Brom's technique with two glutaraldehyde-treated autologous pericardial patches, using recent advanced preoperative information, including geometric and effective heights. Echocardiography after the surgery revealed release of SVAS without aortic regurgitation. CONCLUSIONS: In repair for SVAS, it is important not only to release stenosis but also to make a functional aortic valve, using recent advanced preoperative information. In the case of children, repairing the aortic valve by only using autologous tissue having growth potential, is also important.
