Point-of-care handheld echocardiography (Hand held echocardiograph – Representative image) Initially echocardiographs were large machines with poor resolution. Later advances in electronics miniaturized the machines while improving the resolutions.
Assessment of myocardial viability by echocardiography: Echocardiographic techniques are safe and do not have the risk of ionizing radiation like nuclear perfusion studies and positron emission tomography. But
Myocardial contrast echocardiography (MCE) has been used in the assessment of myocardial viability. Myocardial segments with normal perfusion and those with patchy perfusion are considered to be viable.
