Adult Echocardiography Protocol



Patient Position
o
For parasternal and apical views have the patient lie in the left lateral decubitus (LLD) position with left
arm raised above the head. Obtain an adequate ECG which includes visualization of the P wave, QRS
complex, and T wave.
o
For subcostal view have the patient lay on their back and bend their knees to soften the abdominal
muscles.
o
For suprasternal notch view have the patient lay on their back with a pillow under their shoulders to
allow for the probe to be rotated correctly
Cardiac Heart Beats
o
Capture 2 cardiac heart beats per cine loop unless an abnormal rhythm is present
o
Change the number of cardiac heart beats captured from 2 to 4-5 for patients with the following
abnormalities: atrial fibrillation, significant arrhythmias, rapid heart rate (with a R wave to R wave
greater than 500 m/sec on the ECG)
Gray Scale Imaging
o



Adjust overall gain and TGC so that the ventricular and atrial cavities are anechoic
Color Doppler
o
Adjust color gain until Doppler noise is seen, then decrease the gain down just enough to eliminate the
noise.
o
Keep your color box narrow for better resolution
Correct
Spectral Doppler
o
The angle of incidence should be less than 20°
o
Obtain 3 consecutive waveforms, measuring the middle waveform
Continuous wave Doppler
o
Perform continuous wave Doppler tracing on all valves with a velocity greater than 2m/sec

o

Too
wide
For the mitral valve, include the pressure ½ time
Perform continuous wave Doppler tracing on all valve replacements and repairs

Pharmaceutical Contrast
o
May be utilized upon receiving a written order from the physician.
o
Pharmaceutical contrast is indicated for use in patients with 2 or more suboptimal wall segments of the
left ventricular endocardial borders.
o
Pharmaceutical contrast is contraindicated for patients with known or suspected:

Right-to-left and bi-directional cardiac shunts

Cardiovascular or pulmonary compromise

Hypersensitivity to perflutren (lipid micro gas), blood products or albumin (egg white allergy)
Aortic Stenosis Additional Views
o
Interrogate the aortic outflow with non-imaging pedoff probe from the suprasternal notch window.
o
Reposition the patient to right lateral decubitus (RLD) position and interrogate the aortic outflow with
non-imaging pedoff probe from the right Parasternal window.
o
Acquire multiple spectral Doppler waveforms from both windows and measure to determine the highest
velocity documented.
Technically difficult exams
o
Document normal cardiac windows with limited views
o
Utilize modified views to acquire diagnostic images for physician interpretation
Biplane Simpson’s Method of Discs: Uses the summation of the areas from the diameters of 20 cylinders or discs of
equal height is used to calculate the end- diastolic volume, end-systolic volume, stroke volume, cardiac output, cardiac
index, and ejection fraction.
Labs:

Troponin: an elevated troponin may indicate a myocardial infarction

BNP (Brain natriuretic peptide: an elevated BNP is an indication of the myocardial tissue being stretched as in
