INTRODUCTION: Atrial septal defect (ASD) is one of the most common congenital heart malformations. Although not recommended, a significant proportion of patients with aortic root defects receive ASD closure, some of whom have improved right ventricular function. The study aimed to investigate the safety of interventional therapy in ASD patients with complete aortic rim deficiency and explore the predictors of right atrial (RA) non-reverse remodeling.
METHODS: 1,011 patients with ASD who underwent transcatheter closure in the Department of Cardiology, Zhongshan Hospital, affiliated to Fudan University from June 2017 to June 2023 were enrolled in the study. They were divided into a complete aortic rim deficiency group and without absent aortic rim group. Furthermore, patients who had an enlarged RA in the absent aortic rim group were divided into two subgroups according to whether their RA remodeling was reversed post-procedure. Multivariate logistic regression was used to determine the predictors of RA reverse remodeling.
RESULTS: During the 1-year follow-up, no major operative complications occurred in all patients with the absence of an aortic rim and a normal edge. After the operation, the right heart remodeling was significantly reversed, multivariate logistic regression analysis was performed, and it was found that no coronary heart disease before an operation, lower plasma creatinine level, and larger RA and RV dimensions were the predictive factors for the reverse of RA remodeling after treatment.
CONCLUSION: Transcatheter closure of ASD with complete aortic rim deficiency is safe and feasible. For patients without coronary heart disease, the lower the creatinine value and the lower the tricuspid regurgitation before an operation, the more improvement of RA remodeling after the operation.
