This feasibility study concluded: 'The use of the Ventripoint knowledge-based-reconstruction technique revealed no significant differences in the measurement of left ventricular volumes or ejection fraction in comparison with contrast echocardiography
It covers the history of echocardiography, physics and instrumentation, contrast echocardiography
, the comprehensive echocardiographic examination, evaluation of various cardiologic functions, hemodynamics, various diseases, stress echocardiography, echocardiography in systemic disease and specific clinical presentations, and echocardiography in the intensive care unit, operating room, and electrophysiology laboratory.

Utility contrast echocardiography
in the emergency department.
After balloon inflation, angiographic contrast was injected through the balloon catheter together with simultaneous transthoracic two-dimensional myocardial contrast echocardiography
to determine the extent of the myocardium supplied by the selected septal artery.
In Abrams et al.'s comparison of the diagnostic utility of contrast echocardiography
and lung perfusion scan in patients with HPS, they found a similar prevalence of positive contrast echocardiograms (i.e., with intrapulmonaryvascular dilatations present) across a range of aetiologies and severities .

Echocardiography showed a dilated coronary sinus (CS), suggesting PLSVC, and contrast echocardiography
from the left arm vein showed early CS opacification, before the right atrium and right ventricle.
Presence of intrapulmonary shunting with a twodimensional contrast echocardiography
or a Technetium-99 macroaggregate albumin nuclear test should be documented.
used an in vitro microdialysis circuit and quantified contrast echocardiography
at varied flow rates and similarly found that signal intensities were not influenced by changes in flow .

There diagnostic criteria were as follows: (1) >3 prominent trabecular formations along the left ventricular endocardial border, which are visible in end-diastole, distinct from papillary muscles, false tendons, or aberrant bands, (2) trabeculations move synchronously with the compacted myocardium, (3) trabeculations form the noncompacted part of the two-layer myocardial structure, best visible at endsystole, and (4) perfusion of the intertrabecular spaces from the ventricular cavity is present at end-diastole on color-Doppler echocardiography or contrast echocardiography
. They excluded 11 patients based on their review.
