Abstrakt: Background: Association between secundum Atrial Septal Defect (ASD) and mitral valve (MV) disease has been recognized for decades. Secundum ASD closure can reduce mitral regurgitation (MR) degree. However, in some patients, deterioration of MR after ASD closure has been observed. We aimed to identify the risk factors of MR deterioration after ASD closure. Methods: This was an observational retrospective cohort study. Data were collected from the registry and echocardiogram report. We evaluated all patients with ASD closure by surgery and transcatheterization without MR intervention from January 2012 until June 2021 at Dr. Sardjito General Hospital, Yogyakarta. We excluded patients with multiple ASD and ASD with severe MR requiring MV intervention. Risk factors for MR deterioration were evaluated using multivariate logistic regression. Results: A total of 242 patients who underwent post-secundum ASD closure were included. In multivariate analysis, ASD closure by surgery, large left atrial (LA) diameter (>40 mm), low left ventricular ejection fraction (LVEF; <55%), and MV regurgitation degree were significant risk factors for MR worsening after ASD closure, with OR of 2.103 (95% CI 1.124-3.937); 2.871 (95% CI 1.032-7.985); 5.531 (95% CI 1.368-22.366); and 2.490 (95% CI 1.339-4.630) respectively. Conclusion: ASD closure by surgery, large LA diameter (>40 mm), low LVEF (<55%), and MV regurgitation degree are independent significant risk factors for MR deterioration in post-secundum ASD closure patients. In adult ASD patients with reduced LV function, it is recommended to perform balloon testing and consider fenestrated closure, as low LVEF <55% has the highest risk of causing new or deteriorating MR.
