Diagnostic ME 4-Chamber acquired. Inspect chamber borders, valve motion, or activate Color Doppler.

The universal "home base" of TEE. Slight retroflexion (-5°) eliminates LV apical foreshortening.

Clinical Patient Briefing

TEE Probe Manipulation, Orientation & Safety Guide

Clinical Orientation Rules

  • Near-Field Sector Apex (Top): Represents the ultrasound transducer inside the esophagus (or stomach), immediately posterior to the Left Atrium (LA).
  • 0° Horizontal Plane: Patient's Right (RA, RV) appears on screen-left; Patient's Left (LA, LV, LAA) appears on screen-right (marked by the cyan ASE orientation dot).
  • 90° Longitudinal Plane: Inferior/Posterior structures appear on screen-left (IVC, Inferior LV wall); Superior/Anterior structures appear on screen-right (SVC, LAA, Anterior LV wall).
  • BART Color Flow Doppler: Blue = flow Away from probe; Red = flow Toward probe; green/yellow mosaic indicates high-velocity Nyquist aliasing or turbulent regurgitant/stenotic jets.

Esophageal Mucosal Safety Rules

  • Never Force or Advance While Flexed: Always neutralize the Big and Small wheels toward 0° (press N) before advancing or withdrawing the probe shaft more than 1.5 cm.
  • Keep Friction Brake Unlocked During Depth Changes: Only use the brake briefly to hold a stationary diagnostic plane, never while moving in the esophagus.
  • Gastric Acoustic Coupling: Below the gastroesophageal junction (~40–52 cm), gastric air causes acoustic dropout until you apply Anteflexion (+25° to +48°) to press the crystal gently against the gastric mucosa.

Control Keys Clinical Effect
Withdraw / Advance W / S Moves gastroscope shaft -0.5 cm (cranially) or +0.5 cm (caudally)
Turn Shaft CCW / CW A / D Rotates shaft -4° (toward patient left) or +4° (toward patient right)
Anteflex / Retroflex ↑ / ↓ Turns Big Wheel +3° (curls tip anteriorly) or -3° (posteriorly)
