- 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.
