  • Cardiac tamponade refers to the haemodynamic that occurs when the pressure within a pericardia} effusion compresses the heart. (Video 1)

  • It is a clinical diagnosis indicated by the presence of:

    —Breathlessness (with clear lungs)

    —Tachycardia (>100 beats/min)

    —Pulsus parasoxus (>10mmHg fal in systolic blood pressure during inspiration)

Types Of Tamponade [Figure 1]

  • Acute tamponade
  • Chronic tamponade

  • PWD in the apical 4-chamber view to interrogate tricuspid and mitral inflow.
  • PW Doppler in the parasternal short axis view to interrogate RVOT flow and record both the velocity time integral (VTI) and peak velocity (Vmax).
  • The normal respiratory variability in both is <10 percent,but is greater in the presence of tamponade.
  • IVC is dilated with absent inspiratory collapse.

Massive Pericardial Effusion- The Swinging Heart

  • Apical 4C PE swinging heart (Video 2)

  • Apical 4C PE mitral inflow Doppler (Video 3)

  • Apical4C PE tricuspid inflow Doppler (Video 4)

  • PLAX PE swinging heart (Video 5)

Cardiac Tamponade Occurring After Cardiac Surgery (video 6)

If no hypotension, look for

—Unsuspected hypovolemia

—Ventricular dysfunction

—Or LVOT obstruction
