A successful surgical repair for supravalvular aortic stenosis with a bicuspid valve and malpositioned coronary orifices by partial Brom’s technique: a case report

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.

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.

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.
