All About Cardiovascular System and Disorders

Ventricular interdependence is the term used to describe the dysfunction of one ventricle secondary to a disorder of the other.

A palpable pericardial rub is known as pericardial fremitus. It is due to the friction between the parietal and visceral layers of the pericardium.

Multislice computed tomography for assessing myocardial viability: Iodinated contrast used for CT scanning accumulate in infarcted myocardium similar to what happens with late gadolinium enhanced (LGE) magnetic resonance

Cardiac magnetic resonance (CMR) imaging can be used to assess myocardial viability. Preserved myocardial wall thickness of more than 5.5 mm has a good sensitivity of 95%, but

Positron emission tomography (PET) is usually taken as the gold standard for assessment of myocardial viability. A mismatch between perfusion and metabolism whereby underperfused region of myocardium is

Balanced myocardial ischaemia If all three major coronary branches have similar degree of stenosis, the radionuclide used for perfusion study will have equal uptake in all regions of

Single photon emission computed tomography (SPECT) - pros and cons: Important advantages of SPECT are that it has been extensively validated and has a good sensitivity, compared to

Thallium 201 single photon emission computed tomography (SPECT) Thallium 201 SPECT imaging is one of the oldest methods of assessing myocardial viability, though of late it is seldom

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
