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
Strain and strain rate imaging for myocardial viability: Myocardial strain is a measure of deformation of a myocardial segment relative to its initial length. Strain rate is the
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.
Echocardiographic assessment of myocardial viability Echocardiographic assessment of myocardial viability: Diastolic wall thickness will give an idea regarding the myocardial viability. Thin and hyperdense myocardium is likely to
In triphasic left ventricular filling pattern, described in hypertrophic cardiomyopathy, an additional mid diastolic wave which is called T wave or L wave is seen. A corresponding L'
