Introduction
 

The Parasternal Short Axis view at the aortic valve level allows for 2D assessment of the aortic valve, tricuspid valve, pulmonic valve, right ventricular function, and identification of the cusps of the aortic valve.   Color flow Doppler assessment of the tricuspid valve and pulmonic valve is evaluated in this view. Continuous wave Doppler can be performed through the tricuspid valve and the pulmonic valve, and right-sided cardiac output using spectral Doppler through the right ventricular outflow tract can be accomplished in this view.  The anterior pericardium can be seen, and systolic right atrial collapse or diastolic right ventricular collapse suggesting cardiac tamponade can be evaluated in this view.

The important structures to evaluate in this view are:

  • Left Atrium (LA)
  • Interatrial Septum (IAS)
  • Right Atrium (RA)
  • Tricuspid Valve (TV)
  • Pulmonary Valve (PV)
  • Pulmonary Artery (PA)
  • Aortic Valve (AV)
LA = Left Atrium
IAS = Interatrial Septum
RA = Right Atrium
TV = Tricuspid Valve
RVOT =Right Ventricular Outflow Tract
PV = Pulmonary Valve
PA = Pulmonary Artery
AV = Aortic Valve
RCC = Right Coronary Cusp
LCC = Left Coronary Cusp
NCC = Non Coronary Cusp

The short axis view of the aortic valve shows the right coronary cusp, the left coronary cusp, and the non-coronary cusp. If the beam is angled superior to the aortic valve, the ostia of the left main and right coronary arteries, usually at 4 and 11 o'clock respectively, can be present. Note that the aortic and pulmonary valves are orthogonal to each other. Sometimes, the left atrial appendage is present. The LA, RA and Interatrial septum are present. The tricuspid valve with the posterior leaflet (PL) are present. The RVOT, RV free wall, PV, and main PA are present. Distal in the PA are the left and right pulmonary arteries.
