目的：探讨X线胸片、超声、心导管、心血管造影对双腔右心室诊断价值。材料与方法：选择13例经手术证实为双胜右心室的病例，并均有X线胸片、超声、心导管及心血管造影资料，对这四种影像检查进行分析对照。结果：X线胸片无特征性改变，超声正确率仍较低，心导管、心血管造影正确率高于超声。结论：双腔右心室术前确诊应选择心导管及心血管造影检查。
Objective: To evaluate the value of X-ray, ultrasound, cardiac catheterization and cardiovascular angiography in the diagnosis of double-chamber right ventricle. MATERIALS AND METHODS: Thirteen cases were confirmed as Shuangsheng right ventricle by operation. X-ray, ultrasound, cardiac catheterization and cardiovascular angiography were used to analyze and contrast the four imaging examinations. Results: There was no characteristic change of X-ray, the correct rate of ultrasound was still low, and the correct rate of cardiac catheterization and cardiovascular angiography was higher than that of ultrasound. Conclusions: Cardiac catheterization and coronary angiography should be performed before the diagnosis of double-chamber right ventricle.
