We report a successful case of aortic valve-sparing root replacement for dilated aortic root after a Ross procedure. A 29-year-old male underwent a Ross procedure when he was 11 years old for congenital aortic bicuspid valve. The right ventricular outflow tract was reconstructed using an autologous pericardium as a single leaflet valve. Aortic root dilatation and moderate aortic valve regurgitation were noted. Further investigation with enhanced computed tomography and ultrasonic cardiography revealed good quality of leaflets and sufficient geometric height, and aortic valve-sparing root replacement was performed. In addition, we performed pulmonary valve replacement with a biological valve. The post-operative course was uneventful and the patient was discharged after 8 days with a completely controlled aortic valve regurgitation. No recurrence of aortic valve regurgitation was observed 1 year later. Because surgical outcomes of congenital heart diseases have improved and more patients have an increasing life expectancy, several other problems were revealed, such as the occurrence of aortic root dilatation after a Ross procedure. Aortic roots may dilate due to arterial pressure; however, valve-sparing procedures may be performed if the volume of the leaflets is sufficient.
