From: Transthoracic echocardiographic imaging of coronary arteries: tips, traps, and pitfalls

  Probe Delivery frequencies Color Doppler PRF Wall Filters Pulse Doppler filters Focus Anatomical reference
LAD 4–8 MHz as 2nd harmonic 15–25 cm/s high low on Anterior interventricular sulcus
PDCA 3.5–5 MHz as 2nd harmonic 15–25 cm/s high low on Posterior interventricular sulcus
  1. LAD = Left anterior descending coronary artery
  2. PDca = Posterior descending coronary artery
