Abstract:
A baby girl with a low birth weight was given a diagnosis of congenital bicuspid aortic stenosis and mitral valve prolapse. At the age of 40 days, she underwent balloon aortic valvotomy, but significant aortic regurgitation appeared afterwards. Another surgical intervention became necessary by the age of 20 months (weight, 5.7 kg), because of intractable heart failure mostly caused by exacerbated mitral regurgitation. We performed a leaflet extension valvuloplasty for the small bicuspid aortic valve using an autologous pericardium treated by glutaraldehyde. The mitral valve was replaced with an ATS-16AP valve. Although her postoperative course was complicated with mitral paravalvular leakage and poor left ventricular function, she was discharged from hospital 6 months post operatevely. Leaflet extension valvuloplasty is a surgical option for infants with a small aortic annulus, but the procedure could be the only solution in cases when Konno or Ross techniques are not suitable.
