摘要: 选择50例轻度二尖瓣狭窄疾病患者纳入观察组,另选主动脉瓣关闭不全患者50例作为参考组,通过多普勒超声心动图评估两组患者的收缩期和舒张期右心室功能。结果显示,两组的二尖瓣口面积、右心室射血分数、右心室内径、室间隔舒张末期厚度、右室前后径,以及流入道、流出道、右心室、心尖肌小梁的右心室局部舒张末期容积和右心室局部收缩末期容积差异明显,有统计学意义(P<0.05)。利用多普勒超声心动图评估轻度二尖瓣狭窄,对患者早期风险评估有重要的临床参考价值。

Abstract: 50 patients with mild mitral stenosis were selected as the observation group, and another 50 patients with aortic valve insufficiency were selected as the reference group. Systolic and diastolic right ventricular function of the two groups were evaluated by Doppler echocardiography. The results showed that there were significant differences in mitral valve orifice area, right ventricular ejection fraction, right ventricular diameter, interventricular septal end diastolic thickness, right ventricular anteroposterior diameter, right ventricular regional end diastolic volume and right ventricular local end systolic volume of the inflow tract, outflow tract, right ventricle, and apical muscle trabeculae between the two groups (P<0.05). Using Doppler echocardiography to evaluate mild mitral stenosis has important clinical reference value for early risk assessment of patients.

Key words: mild mitral stenosis, color Doppler ultrasound, systolic, diastolic, right ventricular function
