Doming of the pulmonary valve is considered an important angiographic sign for valvar stenosis. But, this sign cannot be used with similar specificity following valvotomy because at the time of surgery a bicuspid valve is created. Pre- and postoperative hemodynamic data and right ventriculograms are reviewed in 22 patients with simple pulmonary valvar stenosis. There was no correlation between the transvalvar gradient and appearance of the pulmonary valve after surgery.
肺动脉瓣圆顶状突出被认为是瓣膜狭窄的一个重要血管造影征象。但是，在瓣膜切开术后，由于手术时形成了二叶式瓣膜，这个征象就不能以类似的特异性来使用了。回顾了22例单纯肺动脉瓣狭窄患者术前和术后的血流动力学数据及右心室造影片。术后跨瓣膜压差与肺动脉瓣外观之间没有相关性。
