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 .
Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
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.
The use of ICE is specialized and not intended for general echocardiography due to its cost and invasiveness. [1] [2] It is used as a part of a larger heart procedure.A typical use of ICE is for performing a transseptal puncture across the interatrial septum; in other words, pushing a catheter from the right atrium to the left atrium.
Janeway lesion; Osler's node; At the nails Splinter hemorrhage and Quincke's pulsation should be looked for as well as any deformity of the nail such as Beau's lines, clubbing or peripheral cyanosis. Inspect the head for: Cheeks for the malar flush of mitral stenosis. The eyes for corneal arcus and surrounding tissue for xanthalasma.
Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.
Focus assessed transthoracic echocardiography (or FATE) is a type of transthoracic echocardiogram, or sonogram of the heart, often performed by non-cardiologist.The protocol has been used since 1989 and has four projections; subcostal four-chamber, apical four-chamber, parasternal long axis and parasternal short axis.
Lesion Characterization: contrast-enhanced ultrasound plays a role in the differentiation between benign and malignant focal liver lesions. This differentiation relies on the observation [ 15 ] or processing [ 16 ] [ 17 ] of the dynamic vascular pattern in a lesion with respect to its surrounding tissue parenchyma .
