Cardiac catheterization

• Cardiac tamponade: There is equalization of pressures in all four chambers of heart. The right atrial pressure equals the right ventricular end diastolic pressure equals the pulmonary artery diastolic pressure.
• Constrictive pericarditis: Equalization of elevated right atrial and pulmonary artery wedge pressures may be noted with a diastolic dip and plateau in the right ventricular tracing.
• Effusive constrictive pericarditis: Cardiac tamponade findings are noted initially. Findings of constrictive pericarditis are unmasked following pericardiocentesis.
