Percutaneous balloon aortic valvuloplasty was attempted in an eight-month-old infant with severe aortic valve stenosis. The procedure resulted in a fall in the resting transvalvular systolic pressure gradient from 106 mmHg to 40 mmHg and no aortic regurgitation. Clinical and Doppler echocardiography findings suggest persistent improved status 3 1/2 months after the procedure.
对一名患有严重主动脉瓣狭窄的8个月大婴儿尝试进行经皮气球主动脉瓣成形术。该手术使静息跨瓣收缩压梯度从106 mmHg降至40 mmHg，且无主动脉反流。临床和多普勒超声心动图检查结果表明，术后3个半月病情持续改善。
