Normal pericardium
Inner serous layer is the epicardium Outer fibrous layer is pericardium Space between the two is pericardial space Normally contains about 20-50cc of fluid Fat covers outside of heart and outside of pericardium sandwiching pericardial space between the two layers
Normal thickness of pericardium (parietal pericardium and fluid in space) is 2-4 mm
Requires about 150-250cc before cardiac tamponade occurs

Pericardial effusionPericardial effusionX-ray appearance：
Direct sign：Heart shadow generally enlarge bilaterally “water-bottle” or “flask” shape, globularContour of cardiac border disappearPulsation of the cardiac border weaken or disappear, but the aortal pulsation is normal
Indirect sign：Vena systemica return obstructed, right ventricle output decreased
Superior vena cava widenDecreased lung markings
Aortal shadow smaller
Cardiac tamponade – impedes diastolic filling

Pericardial effusionPericardial effusion
Pericardial effusion on both lateral chest radiograph and axial CT. Red arrow points to fat outside of pericardium. Green arrow points to pericardial space which is 8 mm in this patient (<4 mm is normal.) The yellow arrow points to fat outside of heart and the blue arrow to the myocardium.

Pericardial thickening 、 calcificationthickening：
Pericardium near the diaphragm (ventricular face) thicken obviously but the atrium aera and the root of the great vessels less thickenEpicardial fat pad ‘sign’ (+)
Lat. / PA view: anterior pericardial stripe ＞ 2mm
Hemodynamic change:Right ventricle compression ： venous return obstructed, vena cervicalis and vena cava dilatationLeft ventricle compression ： left atrium and pulmonary venous pressure increased, so the left heart output decreased

Constrictive pericarditisConstrictive pericarditisX-ray ：
Direct sign：The heart shadow size is normal or little, midium enlarged
A side or both sides of heart borders straighten, the demarcation among each arcus is undefined; contour: triangle , globular
Heart pulsation weaken or disappear; the portion without thickened can bulge, and it’s pulsation enhanced
Pericardial calcification ： eggshell, barred, patching,
Pleural thickening, adhesion
Indirect sign ： VP ↑Superior vena cava dilatation

Mitral StenosisRheumatic Valvular Heart Disease
● Rheumatic heart disease causes mitral stenosis in 99.8% of cases
Right Ventricular Hypertrophy
Stenotic mitral valve
© Frank Netter, MD Novartis®
• Mitral stenosis occurs
• Left atrial pressure
• Left atrium enlarges
• Cephalization
• PIE
• PAH develops
• PVR increases
• RV enlarges
• Pulmonic regurg develops
• Tricuspid annulus dilates
• Tricuspid insufficiency
• RV failure
