Abstract
Objectives
Surgical aortic valvuloplasty (SAV) and balloon aortic valvuloplasty (BAV) are two main treatments for children with isolated congenital aortic stenosis (CAS). We aim to compare the two procedures' midterm outcomes, including valve function, survival, reintervention, and replacement.
Methods
From January 2004 to January 2021, children with isolated CAS undergoing SAV (n = 40) and BAD (n = 49) at our institution were included in this study. Patients were also categorized into subgroups based on the aortic leaflet number(Tricuspid = 53, Bicuspid = 36) to compare the two procedures’ outcomes. Clinical and echocardiogram data were analyzed to identify risk factors for suboptimal outcomes and reintervention.
Results
Postoperative peak aortic gradient (PAG) and PAG at follow-up in the SAV group were lower compared with the BAV group (p < 0.001, p = 0.001, respectively). There was no difference in moderate or severe AR in the SAV group compared with the BAV group before discharge (5.0% vs 12.2%, p = 0.287) and at the last follow-up (30.0% vs 32.7%, p = 0.822). There were no early death but three late deaths (SAV = 2, BAV = 1). Kaplan-Meier estimated survivals were 86.3% and 97.8% in SAV and BAV groups respectively at 10 years (p = 0.54). There was no significant difference in freedom from reintervention (p = 0.22). For patients with bicuspid aortic valve morphology, SAV achieved higher freedom from reintervention (p = 0.011) and replacement (p = 0.019). Multivariate analysis indicated that residual PAG was a risk factor for reintervention (p = 0.045).
Conclusions
SAV and BAV achieved excellent survival and freedom from reintervention in patients with isolated CAS. SAV performed better in PAG reduction and maintenance. For patients with bicuspid AoV morphology, SAV was the preferred choice.
期刊介绍:
The Hellenic Journal of Cardiology (International Edition, ISSN 1109-9666) is the official journal of the Hellenic Society of Cardiology and aims to publish high-quality articles on all aspects of cardiovascular medicine. A primary goal is to publish in each issue a number of original articles related to clinical and basic research. Many of these will be accompanied by invited editorial comments.
Hot topics, such as molecular cardiology, and innovative cardiac imaging and electrophysiological mapping techniques, will appear frequently in the journal in the form of invited expert articles or special reports. The Editorial Committee also attaches great importance to subjects related to continuing medical education, the implementation of guidelines and cost effectiveness in cardiology.
