Summary keeping Objectives in mind:

  • Know all the info I included for cardiac tamponade.

  • Focus on the similarities and differences b/t cardiac tamponade and constrictive pericarditis

    • o

      SIMILARITES: symptoms and signs are similar b/c they arise from impaired diastolic filling of the ventricles in both disorders… so I would word it as such: the pathophysiology (the mechanisms that lead to the symptoms) is similar in both diseases but the pathology is different (pericardial fluid under pressure in tamponade; and scarred, rigid pericardium in constrictive pericarditis)… also cardio-cath is most reliable diagnostic tool for both…

  • o

    DIFFERENCES:

Cardiac Tamponade

  • Pulsus paradoxus present

  • No Kussmaul’s sign

  • Y descent blunted in RV pressure reading

  • Echocardiography pretty useful

  • Treat w/ pericardiocentesis

  • Pathology = high pressure fluid compression

Constrictive Pericarditis

  • No pulsus paradoxus

  • Kussmaul’s sign present

  • Accentuated Y descent in RV

  • Echo gives subtle results (MRI better)

  • Treat w/ removal of pericardium

  • Pathology = stiff, fibrotic, scarred

pericardium
