Secundum-type atrial septal defects (ASD) constitute 8% to 10% of congenital heart defect. Secundum ASDs can be closed either percutaneously or surgically. However, ASD device closure has proven to be technically safe and feasible; it is not free of complications. These complications include device embolization/malposition which have been reported in 3.5% of cases, arrhythmia, and pericardial effusion in 2.6% and 0.5–1.5% respectively, device thrombus, residual shunting, and impingement of the device on the adjacent structures. We introduce three patients with secundum ASD who had preexisting pericardial effusion, device closure was performed for them, and after the procedure, the effusion size progressed significantly. We used multimodality imaging to diagnose the cause of pericardial effusion (PE). Cardiac erosion was diagnosed in one of the patients that managed surgically. We did not found any specific procedure-related cause for worsening the pericardial effusion in the other two patients. Several reasons include procedure-related complication and other systemic causes should be considered in patients who develop pericardial effusion after trans catheter closure of ASDs.

ASD 装置闭合后原有心包积液恶化的病例报告：这是灾难性的吗？

继发孔型房间隔缺损 (ASD) 占先天性心脏缺损的 8% 至 10%。Secundum ASD 可以经皮或手术闭合。然而，ASD 设备封闭已被证明在技术上是安全可行的；它并非没有并发症。这些并发症包括装置栓塞/错位（3.5% 的病例报告）、心律失常和心包积液分别占 2.6% 和 0.5-1.5%、装置血栓、残余分流和装置撞击相邻结构。我们介绍了 3 名继发性 ASD 患者，他们之前存在心包积液，对他们进行了装置闭合，手术后积液量显着增加。我们使用多模态成像来诊断心包积液 (PE) 的原因。其中一名接受手术治疗的患者被诊断出心脏侵蚀。我们没有发现任何导致其他两名患者心包积液恶化的特定手术相关原因。在 ASD 经导管闭合后出现心包积液的患者中，有几个原因包括手术相关并发症和其他全身性原因。
