Balloon pulmonary valvuloplasty is a safe and effective treatment for congenital pulmonic valve stenosis. This report describes a child who developed complete atrioventricular (AV) block following balloon pulmonary valvuloplasty. The child was treated with a 10-day course of systemic corticosteroids. The heart block gradually resolved during the first week following the procedure and has not recurred. Heart block is a known complication of right heart catheterization and has been described following balloon pulmonary valvuloplasty. Systemic corticosteroids have been used to treat AV block of various etiologies and may have contributed to the child's recovery in this case.
球囊肺动脉瓣成形术是治疗先天性肺动脉瓣狭窄的一种安全有效的方法。本报告描述了一名儿童在球囊肺动脉瓣成形术后发生完全性房室传导阻滞的情况。该儿童接受了为期10天的全身性皮质类固醇治疗。心脏传导阻滞在术后第一周逐渐缓解，且未复发。心脏传导阻滞是右心导管检查的一种已知并发症，在球囊肺动脉瓣成形术后也有相关报道。全身性皮质类固醇已被用于治疗各种病因引起的房室传导阻滞，在本病例中可能有助于患儿的康复。
