Ruptured sinus of Valsalva aneurysm (RSVA), a rare form of left-to-right shunt, is being increasingly corrected with transcatheter closure (TCC) with promising immediate and mid-term results. Complete heart block (CHB) following TCC of perimembranous ventricular septal defect is a well-described albeit worrisome complication. We describe a hitherto unreported case of development of CHB following TCC of RSVA that responded to high-dose steroids. The patient continues to remain in sinus rhythm without CHB 6 months later.
瓦氏窦瘤破裂（RSVA）是一种罕见的左向右分流形式，越来越多地通过经导管封堵术（TCC）进行治疗，近期和中期结果都很有前景。膜周部室间隔缺损经导管封堵术后发生完全性心脏传导阻滞（CHB）是一种虽已被充分描述但仍令人担忧的并发症。我们描述了一例迄今为止未报告的RSVA经导管封堵术后发生CHB的病例，该病例对大剂量类固醇治疗有反应。6个月后，患者仍维持窦性心律，未再发生CHB。
