Abstract:
Objective:To compare the results of surgical valvuloplasty and balloon dilation in patients with aortic stenosis (AS) at our center.Methods:We retrospectively reviewed the clinical data of children diagnosed with AS, underwent aortic repair or balloon dilation from January 2008 to December 2019. Seeking to analyze the early and long-term valvular function, evaluate mortality and freedom from reoperation by Kaplan- Meier method and figure out the risk factors by logistic regression. Results:There were 116 patients having received surgical valvuloplasty (SAV) and 64 having received balloon dilation (BD). There were no significant differences between two groups respect to median age, weight, preoperative peek gradient, aortic insufficient degree, left ventricular ejection fraction left ventricular end-diastolic dimension Z-score and aortic anulus diameter Z-score ( P>0.05). SAV achieved better gradient reduction and freedom from reoperation than did BD. The mean follow-up time was (5.2±3.1) years in SAV and (4.5±2.1) years in BD. Survival at 10 year was comparable between 2 groups ( P=0.51). Freedom from reoperation at 10 years was 59.6% in SAV and 49.7% in BD respectively ( P=0.01). Multivariate analysis revealed that BD contributed to subsequent reoperation ( P=0.05). Conclusion:SAV and BD both significantly relieved aortic stenosis and obtained good survival benefit. SAV yielded better gradient reduction and lower reoperation risk. BD might increase the hazard of reoperation.
