Abstract
Our study demonstrates the feasibility of substituting FA recordings, corrected for both temporal delay and systolic amplification, for central aortic recordings in assessing aortic valve stenosis. This method is accurate in estimating the transaortic valve gradient, the calculated valve area, and the calculated valve resistance, and obviates the risks and costs of 2 FA punctures.
摘要
我们的研究证明了在评估主动脉瓣狭窄时，用经时间延迟和收缩期放大校正的股动脉（FA）记录替代中心主动脉记录的可行性。该方法在估计跨主动脉瓣压差、计算瓣膜面积和计算瓣膜阻力方面是准确的，并且避免了两次股动脉穿刺的风险和费用。
