ME 4 Chamber View

The ME 4C view (0°) is obtained by positioning the probe in the mid-esophagus behind the LA. The imaging plane is directed thru the LA, center of the MV and apex of the LV. A snapshot of the heart is obtained that includes all 4 chambers (LA, RA, LV, RV), 2 valves (MV, TV), the septums (IAS, IVS) and the inferoseptal and anterolateral LV walls. Segments of the anterior (A2) and posterior (P2) mitral valve leaflets are typically imaged in this view.


To Obtain the View

  • Insert probe to the ME / sector depth 14cm, angle 0-10°
  • Image all 4 heart chambers
  • Optimize the LV apex by slight retroflexion of probe tip
  • Ensure no part of the Aortic Valve or LVOT is seen (advance probe)
  • Aim to maximize the TV diameter, and adjust depth to view entire LV

    • Identify the Following Structures

  • Left Atrium (LA)
  • Right Atrium (RA)
  • Left Ventricle (LV): inferoseptal (IS) + anterolateral (AL) walls
  • Right Ventricle (RV)
  • Mitral Valve: anterior(AMVL) + posterior (PMVL) leaflets
  • Tricuspid Valve: septal (STVL) + anterior (ATVL) leaflets

    • Use this view to Diagnose

  • Chamber size
  • Ventricular function
  • Mitral Valve disease
  • Tricuspid Valve disease
  • Atrial Septal Defect
  • Pericardial Effusion
