- Should be done if:
-LA or LV enlargement
-MR, PR or AR
-When all left heart cannot be visualized adequately from right side
- Left Parasternal Long Axis View of RVOT and PA
-Place transducer in left 3rd ICS and aim straight across the thorax and the
scan plane marker facing cranially for PV
Should image the pulmonary artery (PA), pulmonic valve (PV), tricuspid valve (TV),
right ventricle (RV), and aortic root (AR).
- Left Parasternal Long Axis View of LVOT and AR
-Place transducer in left 4th ICS and aim straight across the thorax with scan
plane marker facing dorsally and slightly cranially for the AR
Should image the left ventricle (LV), left ventricular outflow tract (LVOT), aortic
valve (AV), and aortic root (AR).
Left Parasternal Long Axis View of Mitral Valve
-Place the transducer in the left 5th ICS and aim straight across the thorax
with scan plane marker facing dorsally and slightly cranially
Should image the left atrium (LA), mitral valve (MV), and left
-Internal diameter of LA at its widest point parallel to MV should not exceed
13.5 cm in normal Thoroughbreds, Standardbreds, and Warmbloods.
