The Ross Operation In Neonates: The Best Choice? Stefano Congiu1, Sergio De salvatore2, Antonio Segreto2, Subbarayalu Balaji1, Chiusaroli Alessandro2, Federico Bizzarri2. 1Leeds Children Hospital, Leeds, United Kingdom, 2Università di Roma la Sapienza, Latina, Italy. OBJECTIVE: The Ross procedure was first described in 1967 for the treatment of aortic valve disease in adults. This procedure has been lastly applied to neonates and infants expecially for severe left ventricular outflow tract obstruction (LVOTO) and severe aortic valve disease. The potential for growth and the proven durability make the autograft an ideal aortic valve substitute. METHODS: 5 neonates less than 30 days of age underwent a Ross procedure. The median weight was 3.2 kg. Three patients had a LVOTO with different degrees of endomiocardial fibroelastosis. Two of them had a severe aortic regurgitation with dysplastic aortic valve after aortic valvuloplasty. Three neonates required with a bovine yugular valve conduit and two of them a aortic homograft for the reconstruction of the RVOT. RESULTS: There were no death with complete recovery of the left ventricular function in all cases. The autograft only showed trivial aortic insufficiency with no residual LVOTO on Doppler echocardiography. The telediastolic volume increased to more than 20 ml/m² and telediastolic pressure decreased to normal values before discharged from the hospital. The median hospital stay was 16 days without complications. All the patients are free of operation or complications with a follow-up of 5 years. CONCLUSIONS: There were no death with complete recovery of the left ventricular function in all cases. The autograft only showed trivial aortic insufficiency with no residual LVOTO on Doppler echocardiography. The telediastolic volume increased to more than 20 ml/m² and telediastolic pressure decreased to normal values before discharged from the hospital. The median hospital stay was 16 days without complications. All the patients are free of operation or complications with a follow-up of 5 years.
