Thirty-three consecutive patients with aortic stenosis underwent a 16-row spiral CT scan. Aortic valve planimetry was performed using two methods: double-oblique reformation (DO) and 2D-curved multiplanar reconstruction using advanced vessel analysis software (VA). The mean aortic valve area determined by transthoracic echocardiography was 0.88+/-0.34 [0.53-1.88] and did not differ significantly from that determined by CT (DO): 0.87+/-0.38 [0.42-1.93] (p=0.75) or CT (VA): 0.87+/-0.38 [0.44-2.00] (p=0.69). This study demonstrates that 16-row spiral CT scan is a feasible, accurate and reproducible method for aortic valve planimetry in patients with aortic stenosis. Both methods show similar accuracy but the VA method takes slightly longer.
连续33例主动脉瓣狭窄患者接受了16排螺旋CT扫描。采用两种方法进行主动脉瓣平面测量：双斜位重建（DO）和使用先进血管分析软件（VA）的二维曲面多平面重建。经胸超声心动图测定的平均主动脉瓣面积为0.88±0.34[0.53 - 1.88]，与CT（DO）测定的结果0.87±0.38[0.42 - 1.93]（p = 0.75）或CT（VA）测定的结果0.87±0.38[0.44 - 2.00]（p = 0.69）相比，差异无统计学意义。本研究表明，16排螺旋CT扫描是一种用于主动脉瓣狭窄患者主动脉瓣平面测量的可行、准确且可重复的方法。两种方法显示出相似的准确性，但VA方法所需时间略长。
