Intravascular Imaging
Intravascular imaging is a catheter based system that allows physicians such as interventional cardiologists to acquire images of diseased vessels from inside the artery. Intravascular imaging provides detailed and accurate measurements of vessel lumen morphology, vessel size, extension of diseased artery segments, vessel size and plaque characteristics. Examples of intravascular imaging modalities are intravascular ultrasound (IVUS) and intracoronary optical coherence tomography (OCT or IVOCT).

Intravascular Ultrasound
Intravascular ultrasound (IVUS) or intravascular echocardiography is a medical imaging methodology using a specially designed catheter with a miniaturized ultrasound probe attached to the distal end of the catheter. The proximal end of the catheter is attached to computerized ultrasound equipment. It allows the application of ultrasound technology, such as piezoelectric transducer or Capacitive micromachined ultrasonic transducers, CMUT, to see from inside blood vessels out through the surrounding blood column, visualizing the endothelium (inner wall) of blood vessels. The artery, arteries of the heart (the coronary circulation, coronary arteries) are the most frequent imaging target for IVUS. IVUS is used in the coronary arteries to determine the amount of atheroma, atheromatous plaque built up at any particular point in the epicardial coronary artery. Intravascular ultrasound provides a unique method to study the regression or progression of atherosclerotic lesions in vivo. T ...

Intracoronary Optical Coherence Tomography
Endoscopic optical coherence tomography, also intravascular optical coherence tomography is a catheter-based imaging application of optical coherence tomography (OCT). It is capable of acquiring high-resolution images from inside a blood vessel using optical fibers and laser technology. One of its main applications is for coronary arteries, which are often treated by endoscopic, minimally invasive surgical procedures. Other applications for peripheral arteries and for neurovascular procedures have been proposed and are being investigated. Neurovascular applications required significant technological developments, due to the highly tortuous anatomy of the cerebrovasculature. Intravascular OCT rapidly creates three-dimensional images at a resolution of approximately 15 micrometers, an improved resolution with respect to intravascular ultrasound and coronary angiogram, the other imaging techniques. This offers additional information that can be used to optimize the treatment an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fractional Flow Reserve
Fractional flow reserve (FFR) is a diagnostic technique used in coronary catheterization. FFR measures pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia). Fractional flow reserve is defined as the pressure after (distal to) a stenosis relative to the pressure before the stenosis. The result is an absolute number; an FFR of 0.80 means that a given stenosis causes a 20% drop in blood pressure. In other words, FFR expresses the maximal flow down a vessel in the presence of a stenosis compared to the maximal flow in the hypothetical absence of the stenosis. Procedure During coronary catheterization, a catheter is inserted into the femoral (groin) or radial arteries (wrist) using a sheath and guidewire. FFR uses a small sensor on the tip of the wire (commonly a transducer) to measure pressure, temperature and flow to determin ...

European Heart Journal
The ''European Heart Journal'' is a peer-reviewed medical journal of cardiology published by Oxford University Press on a weekly basis, on behalf of the European Society of Cardiology. The first issue was published in February 1980. Overview The medical journal publishes both clinical and scientific papers on all aspects of cardiovascular medicine. It includes articles related to research findings, technical evaluations, and reviews. In addition, the journal features reviews, clinical perspectives, podcasts, and editorial articles about recent developments in cardiology, and encourages correspondence from its readers. Another important aspect of the journal are the ESC Clinical Practice Guidelines, which cover all areas of cardiology. In 2020, the journal had an impact factor of 29.983, ranking it as one of the highest journals in the field of cardiology. Thomas F. Lüscher (Royal Brompton and Harefield Hospital Trust and Universität Zürich) was succeeded by Filippo Crea as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
