Examination is begun by placing the transducer in left parasternal region, usually in the third or fourth left intercostal space. From this position, a sector image of the heart along its lcbng and short axis can be obtained.
Parasternal Long Akis View
The parasternal lona axis view is acquired with the ridge of the transducer pointing towards tht$ patient's right shoulder. Angling the beam, toward the right hip brings the right ventricular inflow into view. Angling the beam towards the right shoulder allows evaluation of right ventricular outflow tract.
Various structures visualized are LV, LA, MV, RV, LVOT and AV, ascending aorta.
Parasteranl Short Axis Vim
With the transducer placed in the parasternal position (third or fourth left intercostals space), the probe is then turned 90" clockwise from parasternal long axis view to obtain short axis view. The ridge now points towards left shoulder and observation is made at four levels:
1) At the level of great vessels
2) Mitral valve
3) Papillary muscles
4) Apex
