Virtual histology.
As a luminogram, coronary angiography provides a good overview of the coronary artery tree. Using quantitative coronary measurements, the degree of coronary obstruction can be determined. The limitation of coronary angiography is that it does not provide information on the arterial wall structure and therefore cannot assess the extent of atherosclerosis. Knowledge about adaptive coronary remode...
متن کاملAnimal Models and Virtual Histology
We appreciate the interest of Dr Virmani and her colleagues in our article. The study of vulnerable plaque remains controversial and is thus open to dynamic and creative insights. We hoped that our paper would be provocative and initiate some discussion in that regard. As Dr Virmani implies, the argument concerning the adequacy of currently available animal models of atherosclerosis will likely...
متن کاملImaging coronary artery histology: a virtual pursuit?
For years, patients have been under the misconception that a coronary intervention of a coronary stenosis was “preventing an impending heart attack.” As cardiologists, we know better. In stable coronary artery disease, when we perform a coronary intervention, we do not know if the target site is going to evolve into a ruptured plaque and result in acute coronary syndrome. Prediction and prevent...
متن کاملDo systemic risk factors impact invasive findings from virtual histology? Insights from the international virtual histology registry.
AIMS Cardiovascular risk factors such as elevated serum lipid levels are important in the development of coronary atherosclerosis. Radiofrequency (RF) analysis of intravascular ultrasound [IVUS, Virtual histology (VH)] offers a unique tool to study the composition of coronary atherosclerotic plaque in vivo. We used data from the multicentre VH registry to assess the association between cardiova...
متن کاملVirtual histology of an acute thrombotic occlusive lesion.
Rev Esp Cardiol. 2009;62(6):704-12 705 necrotic core near the lumen with no evidence of a fibre cap, a calcium component of 26.9%, a 55% plaque content, and positive remodelling of 1.06. Posteriorly and distally, we find the most stenotic zone, with a luminal area of 2.1 mm.2 Further on, there is a 10.2 mm segment that corresponds angiographically with the image of the thrombus, and which in th...
