The authors report the first case of successful double-balloon valvuloplasty for treatment of severe valvular aortic stenosis at Queen Sirikit National Institute of Child Health, Bangkok, Thailand. The patient was a 7-month-old, 6 Kg weighed infant with the pressure gradient across the aortic valve of 76 mmHg and aortic valve annulus of 10 mm diameter. The procedure was performed under general anaesthesia. The catheterization data revealed left ventricular and ascending aorta pressure of 156/1 and 52/30 mmHg, respectively. After the procedure the left ventricular pressure decreased to 114/0, left ventricular-aortic pressure gradient to 46 mmHg and no significant aortic regurgitation. He was well at 1-month follow-up with the left ventricular-aortic pressure gradient of 12 mmHg and no significant aortic regurgitation.
作者报告了泰国曼谷诗丽吉王后国家儿童健康研究所成功进行双球囊瓣膜成形术治疗重度主动脉瓣狭窄的首例病例。该患者为一名7个月大、体重6千克的婴儿，主动脉瓣跨瓣压差为76毫米汞柱，主动脉瓣环直径为10毫米。手术在全身麻醉下进行。心导管检查数据显示左心室和升主动脉压力分别为156/1和52/30毫米汞柱。术后左心室压力降至114/0，左心室-主动脉压力梯度降至46毫米汞柱，且无明显主动脉瓣反流。1个月随访时情况良好，左心室-主动脉压力梯度为12毫米汞柱，无明显主动脉瓣反流。
