The purpose of this study is the long term follow-up of the first pulmonary valvuloplasties performed by our group. From september 1984 to march 1988, 10 patients (4 men and 6 women) aged 8 to 58 (mean: 21) with severe or moderate pulmonary valve stenosis underwent pulmonary valvotomy. In all cases the balloon diameter was equal to or 1 mm smaller than the valvular annulus. The results were satisfactory with a significant mean gradient reduction of 51.7%. A follow-up gradient estimation by Doppler echocardiogram was obtained 10 to 37 months after valvuloplasty (mean: 23 months). The mean follow-up gradient by Doppler (31.3 +/- 9.9 mmHg) was not significantly different from the mean hemodynamic post-dilatation gradient (35.6 +/- 14.7 mmHg). A linear correlation was found between the post-dilatation hemodynamic mean gradient and the mean gradient by Doppler follow-up (r = 0.66, p less than 0.05, SEE = 4.1 mmHg). No restenosis were observed. These results suggest that the benefits of valvuloplasty are long lasting. Continuous Doppler is an excellent technique for the follow-up of these patients.
本研究的目的是对我们团队实施的首例肺动脉瓣成形术进行长期随访。从1984年9月至1988年3月，10例年龄在8至58岁（平均21岁）、患有重度或中度肺动脉瓣狭窄的患者（4名男性和6名女性）接受了肺动脉瓣切开术。在所有病例中，球囊直径等于瓣膜环或比瓣膜环小1毫米。结果令人满意，平均压差显著降低了51.7%。在瓣膜成形术后10至37个月（平均23个月）通过多普勒超声心动图进行了随访压差评估。多普勒随访的平均压差（31.3±9.9 mmHg）与扩张后平均血流动力学压差（35.6±14.7 mmHg）无显著差异。在扩张后血流动力学平均压差与多普勒随访平均压差之间发现了线性相关性（r = 0.66，p＜0.05，标准误 = 4.1 mmHg）。未观察到再狭窄。这些结果表明瓣膜成形术的益处是持久的。连续多普勒是对这些患者进行随访的极佳技术。
