摘要:
 目的：研究三维成像技术在心脏瓣膜病患者中的应用。 方法：选取2016年4月~2017年9月接收疑似心脏瓣膜病患者98例，按照入院先后顺序分为研究组和对照组，各49例。对照组采用二维超声检查，研究组进行三维超声成像技术检查，两组患者的病理结果与影像结果进行比较，对两组患者的左室整体应变相关参数（GLS、GCS、GRS、GLSendo、GLSepi、GCSendo、GCSepi）进行对比分析，对两组患者的心动图LVDd、LAD、LVEF相关指标进行对比分析，对两组患者的超声特征进行对比。 结果：研究组患者的病理检查结果与影像检查结果一致，对照组患者48例影像检查结果与病理结果一致。研究组患者的左室整体应变参数GLS、GCS、GRS、GLSendo、GLSepi、GCSendo、GCSepi较对照组患者低，差异有统计学意义（P<0.05）。研究组患者心动图LVDd、LAD相关指标高于对照组，LVEF指标低于对照组，差异有统计学意义（P<0.05）。研究组患者的影像显示瓣膜联合处增厚、挛缩、钙化，瓣口面积较为狭窄，且瓣口关闭时对合不严，瓣膜表面粗糙不平，可以多角度立体化观察病灶部位和病变程度。对照组患者显示瓣膜联合处增厚、挛缩、钙化，病灶边界较为模糊。 结论：三维成像技术可以立体显示心脏瓣膜病变部位和程度，为临床研究提供价值更高的信息，对瓣膜手术具有肯定的指导作用。
Abstract:
 Abstract: Objective To investigate the diagnostic value of three-dimensional imaging techniques in patients with valvular heart disease. Methods A total of 98 patients with suspected valvular heart disease who were admitted to Mianyang Central Hospital from April 2016 to September 2017 were randomly divided into study group and control group, with 49 patients in each group. Two-dimensional ultrasonic imaging technology was adopted in control group, and three-dimensional ultrasonic imaging technology in study group. The imaging results were than compared with the pathological results of the two groups of patients. The left ventricular global strain parameters (GLS, GCS, GRS, GLSendo, GLSepi, Gcsendo, GCSepi), related indexes on cardiogram (LVDd, LAD, and LVEF), and the ultrasonic features were analyzed and compared between the two groups. Results The imaging results of all patients in study group and 48 patients in control group were consistent with their pathological findings. The left ventricular global strain parameters (GLS, GCS, GRS, GLSendo, GLSepi, GCSendo, GCSepi) in study group were lower than those in control group, with statistical differences (P<0.05). Moreover, LVDd and LAD were higher and LVEF was lower in study group than in control group (P<0.05). The image manifestations of the patients in study group included the thickening, contracture, and calcification of the valve joint, narrow valve areas, and rough valve surface. The valves were unable to close properly. The location and degree of lesions could be observed at multiple angles. In control group, thickening, contracture, and calcification were observed at the valve joint, and the lesion boundary was blurred. Conclusion Three-dimensional imaging technology can stereoscopically display the location and degree of valve lesions, providing more valuable information for clinical research and guidance for valve surgery.
