This report suggests that in the absence of aortic regurgitation, Doppler peak and mean gradients are useful predictors of catheter peak-to-peak aortic stenosis gradients >50 mm Hg; however, in the presence of aortic regurgitation, the predictive value diminishes dramatically, but improves when electrographic data are incorporated. We present potentially useful equations to help predict the need for interventional catheterization for valvar aortic stenosis.
本报告表明，在无主动脉反流的情况下，多普勒峰值和平均压差是预测导管峰-峰主动脉瓣狭窄压差>50 mmHg的有用指标；然而，在存在主动脉反流时，预测价值显著降低，但纳入心电图数据时则有所改善。我们提出了可能有用的方程，以帮助预测瓣膜性主动脉瓣狭窄介入导管治疗的必要性。
