We assessed aortic regurgitation (AR) severity by utilizing multiple echo-Doppler variables in comparison with AR severity by aortic root angiography. Patients were divided into 3 groups: mild, moderate, and severe. An AR index (ARI) was developed, comprising 5 echocardiographic parameters: ratio of color AR jet height to left ventricular outlet flow diameter, AR signal density from continuous-wave Doppler, pressure half-time, left ventricular end-diastolic diameter, and aortic root diameter. There was a strong correlation between AR severity by angiography and the calculated echo-Doppler ARI (r = 0.84, p = 0.0001). As validated by aortic angiography, the ARI is an accurate reflection of AR severity.
我们通过使用多个超声多普勒变量评估主动脉反流(AR)的严重程度,并与主动脉根部血管造影评估的AR严重程度进行比较。患者被分为3组:轻度、中度和重度。开发了一个AR指数(ARI),它包括5个超声心动图参数:彩色AR射流高度与左心室流出道血流直径的比值、连续波多普勒测得的AR信号密度、压力半衰期、左心室舒张末期直径和主动脉根部直径。血管造影评估的AR严重程度与计算得出的超声多普勒ARI之间存在很强的相关性(r = 0.84,p = 0.0001)。经主动脉血管造影验证,ARI能准确反映AR的严重程度。
