How would you investigate a patient with constrictive pericarditis ?
• Chest radiograph typically shows normal heart size and pericardial calcification (note: the combination of pulsus paradoxus, pericardial knock and pericardial calcification favours the diagnosis of constrictive pericarditis).
• ECG shows low voltage complexes, non-specific T wave flattening or atrial fibrillation.
• Echocardiogram shows myocardial thickness is normal and may reveal thickened pericardium; normal ventricular dimensions with enlarged atria and good systolic and poor diastolic dysfunction.
Doppler shows increased right ventricular systolic and decreased left ventricular systolic velocity with inspiration, expiratory aug-mentation of hepatic vein diastolic flow reversal.
• CT scan or MRI: shows normal myocardial thickness usually, and pericardial thickening and calcification.
• Cardiac catheterization typically shows identical left and right ventricular filling pressures and pulmonary artery systolic pressure usually
