Pressure-based structural cardiac assessment system and method

The heart valve evaluation system described herein advantageously provides an indicator of heart valve condition, such as a pressure gradient or valve regurgitation index. A heart valve evaluation system may provide an indicator of heart valve condition during cardiac surgery. The pressure gradient indicates the severity or measurement of valve narrowing (or narrowing) by an increase in pressure behind the valve. The valve regurgitation index is indicative of a leakage measurement of the valve. 本文所述的心脏瓣膜评估系统有利地提供了心脏瓣膜状况的指标，例如压力梯度或瓣膜反流指数。心脏瓣膜评估系统可以在心脏手术期间提供心脏瓣膜状况的指标。压力梯度通过在瓣膜后面压力的增加指示瓣膜变窄(或狭窄)的严重程度或测量值。瓣膜反流指数指示瓣膜的泄漏测量值。
