A case of severe pulmonary valvar stenosis and infundibular obstruction has been reported. Infundibular obstruction was so severe that no catheter could be advanced into the pulmonary artery. Propranolol, 0.5 mg given intravenously, reduced the obstruction and allowed the balloon dilatation of the pulmonary valve to be carried out without complication. Subsequently oral propranolol helped to remove the infundibular obstruction. We strongly recommend the use of propranolol when infundibular obstruction is present prior or after the balloon pulmonary valvuloplasty.
已报告一例严重肺动脉瓣狭窄合并漏斗部梗阻的病例。漏斗部梗阻非常严重,以至于无法将导管推进到肺动脉。静脉注射0.5毫克普萘洛尔可减轻梗阻,并使肺动脉瓣球囊扩张得以顺利进行且无并发症发生。随后口服普萘洛尔有助于消除漏斗部梗阻。我们强烈建议,在球囊肺动脉瓣成形术前或术后出现漏斗部梗阻时使用普萘洛尔。
