A 55-year-old woman with a history of resected atrial myxoma with residual patched atrial septal defect (ASD) underwent a successful radiofrequency (RF) ablation of reentry atrial tachycardia. She presented with progressive dyspnea 5 days later. Transesophageal echocardiography revealed a 1-cm right atrial mass attached to the intraatrial septum at the ablation site. Repeat study after anticoagulation for 5 weeks showed complete resolution of the thrombus. Thrombus formation at the site of RF ablation is a potential complication that may require aggressive anticoagulation. Patients with patched ASD might be at higher risk.
一名55岁女性，有切除心房黏液瘤病史，伴有残余修补的房间隔缺损（ASD），成功接受了折返性房性心动过速的射频（RF）消融术。5天后，她出现进行性呼吸困难。经食管超声心动图显示，在消融部位的房间隔上附着有一个1厘米大小的右心房肿块。抗凝治疗5周后的复查显示血栓完全溶解。射频消融部位的血栓形成是一种潜在并发症，可能需要积极抗凝治疗。有修补后ASD的患者可能风险更高。
