Randomization will be performed using a 1:1 allocation ratio with stratification based on (1) PFO device size and (2) sex, employing a block randomization method (mixed block sizes of 4 or 6). This process will be conducted independently through an interactive web response system.\n\nThe beta-blockers used in this study are extended-release beta-blockers, specifically bisoprolol or nebivolol. The choice between bisoprolol and nebivolol will be determined at the discretion of the investigators, with the initial dose set at the minimum dose for each drug (1.25 mg once daily). During the study period, adjustments to the beta-blocker dose, including maintenance or modification, will be made based on the investigators' clinical judgment, taking into account the patient's heart rate, blood pressure, and medication adherence. All reasons for dose adjustments will be documented in detail.\"",[26,27,28,29],"Atrial Fibrillation","Atrial Flutter","Tachycardia, Supraventricular","Heart Septal Defects, Atrial","NOT_YET_RECRUITING","2025-08-07",{"date":33,"type":34},"2025-08-14","ACTUAL",{"date":36,"type":20},"2025-09",{"date":38,"type":20},"2029-05-03",{"name":40,"class":41},"Yonsei University","OTHER"]
