摘要

Between 1986 and Feb. 1993, 20 patients with moderately severe isolated pulmonary stenosis underwent cardiac catheterization and balloon pulmonary valvuloplasty (BPV). Their ages ranged from 7 months to 11 years old (mean 6.2 years), their weights ranged from 8 to 45 kg (mean 14.5 kg). Immediately after BPV, the right ventricular pressure decreased from 89¡Ó21 to 46±16 mmllg (p＜O.OO5). The pressure gradient across the pulmonary valve reduced by 68%, from 68±23 to 24±16 mmllg (p＜O.O05). There was no significant changes in both pulmonary artery pressure (19±4 versus 21±3 mmHg), and aortic pressure (102±11 versus 104±11 mmllg). Successful BPV (pulmonic pressure gradient ＜36 mmHg) was achieved in 15 cases (75%). Among the 5 unsuccessful cases, 2 patients underwent redilatation which had excellent results. Another 2 patients received operations, one was a dysplastic pulmonary valve, the other was due to a gradient across the pulmonary valve ＞ 120 mmHg before BPV. The remaining one had only 40 mmHg gradient after BPV, and he was doing well on follow-up. There were no significant complications in these series. BPV is an effective and safe procedure. It should be the treatment of choice for significant pulmonary stenosis in infants and children.
