Intravascular ultrasound provides a unique method to study the regression or progression of atherosclerotic lesions in vivo. [2] The progressive accumulation of plaque within the artery wall over decades leads to the development of unstable vulnerable plaque which can detach as clots leading to strokes and heart attacks.
[9] [10] A ventricular septal defect arises when the superior part of the interventricular septum, which separates the right and left ventricles of the heart, fails to fully develop. The right ventricle pumps blood to the lungs to get oxygen, while the left ventricle pumps blood to the rest of the body to provide oxygen to tissues.
Classifying cardiac lesions in infants is quite difficult, and accurate diagnosis is essential. The diagnosis of Shone’s syndrome requires an ultrasound of the heart ( echocardiogram ) and a cardiac catheterization procedure, that is, insertion of a device through blood vessels in the groin to the heart that helps identify heart anatomy.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
A medical provider (e.g. doctor) may order tests for further evaluation of a heart murmur. The echocardiogram is a common test used. This is also known as an "echo" or ultrasound of the heart. [1] It shows the heart structures and blood flow through the heart. Further testing is usually done when symptoms that may be of concern are present.
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging , using standard ultrasound or Doppler ultrasound . [ 1 ] The visual image formed using this technique is called an echocardiogram , a cardiac echo , or simply an echo .
(Reuters) -California's public health department reported a possible case of bird flu in a child with mild respiratory symptoms on Tuesday, but said there was no evidence of human-to-human ...
Echogenic intracardiac focus (EIF) is a small bright spot seen in the baby's heart on an ultrasound exam. This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart. EIFs are found in about 3–5% of normal pregnancies and cause no health problems. EIFs themselves have no impact on health or heart ...
