The coronary arteries are the blood vessels that supply the tissues of the heart with blood. Coronary artery disease is a condition in which a plaque accumulates in these blood vessels. This plaque consists largely of fat, cholesterol, and calcium. As more plaque accumulates in these blood ...
TCTAP C-020 Oversized Inflation Technique Using a Scoring Balloon for Severe Calcified Lesion and Non-dilatable-lesion in a Patient with Multivessel Disease Without Traditional Risk Factors: Single Centre Experience Despite developments in coronary interventional cardiology, plaque calcification is a critica...
We hypothesized that we would observe a reduction in inflammatory-driven phenotypes of coronary plaque, including non-calcified coronary plaque burden and lipid-rich necrotic core in those treated with biologic therapy after one-year compared with non-biologic therapy.Elnabawi, Youssef A.Dey, Amit K...
Coronary Intravascular... NK Ktenopoulos,M Sagris,AT Tzoumas - 《European Heart Journal》 被引量: 0发表: 2021年 Efficacy of intravascular lithotripsy (IVL) in coronary stenosis with severe calcification: A multicenter systematic review and meta‐analysis Background With heavily calcified coronary ...
The device, which was approved by the US Food and Drug Administration in October 2013 for use in severely calcified coronary arteries, consists of a rotating, diamond-coated crown that is used prior to stent placement to sand the hard components of plaque, leaving the soft components...
The researchers also found that patients with less complex coronary artery disease did better with stents, because they required fewer stents than those with complex disease. Complex disease includes plaque buildup in vessels that is calcified, causes complete blockage of a blood vessel, occurs at ...
Coronary artery disease kills hundreds of thousands of Americans each year, and it is the most common type of heart disease. Coronary artery disease occurs when the blood vessels of the heart become blocked by plaque, which consists of cholesterol, fat, calcium, and other substances found in ...
The coronary arteries were evaluated for coronary plaque type (calcified [CP], noncalcified [NCP], or partially calcified [PCP]) and coronary stenosis severity >= 70% with the use of coronary CTA. For patients with NCP and PCP, 2 high-risk plaque features were evaluated: low-attenuation ...
Coronary atheroma volume amounted to a median of 50.9 mm3 in patients with CAD, representing 4% of the analyzed coronary lumen volume, and was mainly made of calcified and non-calcified fibrous plaques. At-risk plaques were not frequent (9% of low-attenuation plaques, 15.2% of positive ...
Methods This was a retrospective, single-centered study recruiting patients underwent FFA quantification, coronary angiography and intravascular ultrasound (IVUS). CAC severity was assessed with the maximum calcific angle (arc) of the calcified plaque scanned by IVUS. Patients with an arc ≥ 180° ...
