一名72岁男性，2个月前因二尖瓣严重狭窄行二尖瓣置换术，术后出现呼吸急促、水肿入院。超声心动图未显示二尖瓣或左心室功能障碍；然而，与呼吸相关的室间隔移位是可见的（数据补充中的电影 I）。胸部计算机断层扫描显示双侧胸腔积液和轻微心包积液，但没有心包增厚或钙化的证据。此外，心导管检查显示右心房压力升高并伴有显着的y下降（图1A），测量中心静脉压时出现Kussmaul征（图1B），测量右心室压力时出现下降征和平台征（图1C），以及左右心室舒张压平衡（图1D）。这些血流动力学与缩窄性心包炎一致。
A 72-year-old man underwent mitral valve replacement due to severe mitral stenosis 2 months previously, after which, he developed shortness of breath and edema, and he was admitted to our hospital. Echocardiography did not reveal mitral valve or left ventricular dysfunction; however, a respiration-related ventricular septal shift was visible (Movie I in the Data Supplement). Chest computed tomography revealed bilateral pleural effusion and slight pericardial effusion but no evidence of a thickened or calcified pericardium. In addition, cardiac catheterization showed elevated right atrial pressure with prominent y descent (Figure 1A), Kussmaul sign when measuring central venous pressure (Figure 1B), dip and plateau sign when measuring right ventricular pressure (Figure 1C), and equalization of right and left ventricular diastolic pressures (Figure 1D). These hemodynamics were consistent with constrictive pericarditis.
