Abstract:
Objective:To analyze the short and mid-term efficacy of aortic valvuloplasty with autopericardium on children with aortic valve diseases.Methods:A total of 26 children with aortic valve diseases (stenosis or regurgitation) who underwent aortic valvuloplasty with autopericardium in Fuwai Central China Cardiovascular Hospital from September 2017 to June 2021 were retrospectively analyzed.The short-term and mid-term follow-up data were collected.The maximum aortic valve pressure gradient, subaortic regurgitation area, left ventricular end-diastolic volume (LVEDV) and left ventricular ejection fraction (LVEF) were compared before and after operation.Paired t test was used to analyze the short-term and mid-term efficacy of aortic valvuloplasty with autopericardium on children with aortic valve diseases. Results:All 26 cases were successfully operated, and there were no deaths and serious complications during the follow-up period of (22.96±6.45) months.There was a significant difference between the preoperative and postoperative maximum aortic valve pressure gradient at 1 month ( t=7.85, P<0.05), 6 months ( t=6.43, P<0.05), 1 year ( t=6.16, P<0.05) and 2 years postoperatively ( t=4.22, P<0.05) in children with aortic stenosis or that combined with mild-to-moderate closure.The follow-up data of 9 children with simple aortic stenosis showed that there was a significant difference between the preoperative (8.87±3.57) cm 2 and postoperative aortic regurgitation area at 1 month ( t=6.85, P<0.05), 6 months ( t=5.13, P<0.05), 1 year ( t=6.62, P<0.05) and 2 years postoperatively ( t=5.41, P<0.05). The LVEDV of 26 children was significantly lower at 6 months[(63.54±27.61) mL], 1 year [(53.61±20.20) mL] and 2 years postoperatively [(64.39±17.78) mL] compared with that of preoperative level[(89.42±45.89) mL]( t=3.89, 4.67, 3.58, all P<0.05). The left ventricular pressure and volume decreased, the enlarged heart was narrowed down, and the geometry of the heart was restored.The LVEF of 26 patients also from (61.65±9.67)% before surgery increased to (67.88±4.69)% 6 months after surgery( t=3.68, P<0.05), and increased to (68.62±4.46)% 1 year after surgery( t=4.01, P<0.05), and increased to (67.55±3.09)% 2 years after operation( t=3.01, P<0.05), and the heart function was improved. Conclusions:Aortic valvuloplasty with autopericardium presents an effective short and mid-term efficacy on children with aortic valve diseases, which prevents or delays the aortic valve replacement.
