Abstract
A mitral valve orifice equation has been formulated which allows the computation of mitral valve area (A) from the echographically measurable variables of stroke volume (SV) and diastolic filling period (DFP) in seconds per minute by the formula, A=21 (SV)/(DFP)2. Mitral valve areas computed from M-mode echographic measurements are shown to correlate with areas computed by the Gorlin formula (r-0.90) for resting state conditions of predominant mitral stenosis of clinical grades 2 to 4. The results suggest that, in the absence of wall motion irregularities, M-mode echocardiography can quantitatively assess the mitral valve area in stenosis.
摘要
已制定了一个二尖瓣口面积公式，该公式可根据每分钟的每搏量（SV）和舒张充盈期（DFP，以秒为单位）这些可通过超声心动图测量的变量，通过公式A = 21（SV）/（DFP）²来计算二尖瓣面积（A）。对于临床2至4级主要二尖瓣狭窄的静息状态情况，从M型超声心动图测量计算出的二尖瓣面积与通过戈林公式计算出的面积相关（r = 0.90）。结果表明，在没有室壁运动异常的情况下，M型超声心动图可定量评估狭窄时的二尖瓣面积。
