Abstract
The poststenotic jet phenomenon in aortic valve stenosis observed during angiography was studied by a kinetic model. The model allowed to estimate the linear momentum and the kinetic pressure of the jet, which were found to correlate to the poststenotic width of the ascending aorta indicating that the degree of poststenotic widening may be due to the pressure release from the jet.
摘要
通过动力学模型研究了血管造影术中观察到的主动脉瓣狭窄时的狭窄后射流现象。该模型能够估计射流的线性动量和动压，发现它们与升主动脉的狭窄后宽度相关，这表明狭窄后扩张程度可能归因于射流的压力释放。
