Short-to mid-term outcomes of aortic valve plasty versus Ross procedure in children with severe aortic valve disease:A retrospective cohort study
Objective To compare the short-to mid-term outcomes of aortic valve plasty(AVP)and Ross surgery in children with severe aortic valve disease.Methods The patients(aged＜18 years)with severe aortic valve disease who underwent AVP(an AVP group)or Ross surgery(a Ross group)at the Department of Cardiovascular Surgery,West China Hospital from January 2019 to September 2023 were retrospectively included.We compared perioperative and follow-up data between the groups.Results A total of 48 pediatric patients were included,including 28 males and 20 females,with an average age of(9.3±4.5)years.There were 25 patients in the AVP group,and 23 in the Ross group.Leaflet thinning(15/25,60.0％)and leaflet extension(10/25,40.0％)were the most common strategies used in the AVP group,while root replacement technique(12/23,52.2％)and subcoronary technique(10/23,43.5％)were the most frequently used strategies in the Ross group.There was no in-hospital death.The median follow-up time was 16.0(7.0,30.0)months.Peak flow velocity of the aortic valve was higher in the AVP group[2.0(1.4,2.9)m/s vs.1.2(1.0,1.5)m/s,P＜0.001],while there was no statistical difference in the postoperative aortic valve regurgitation severity between the two groups(P=0.127).During follow-up,the overall reoperation rate and aortic valve reoperation rate were similar between the AVP group and the Ross group(8.0％vs.13.0％,P=0.922;8.0％vs.0.0％,P=0.266).The rate of recurrent aortic valve disease was higher in the AVP group(52.0％vs.4.3％,P＜0.001),while further analysis failed to recognize any risk factors.Conclusion AVP and Ross procedure show similar perioperative safety,survival and reoperation rate.The rate of recurrent aortic valve disease is higher in the AVP group,but further investigations are needed to confirm the causes.
