Characterization of plaque components and vulnerability with intravascular ultrasound elastography.
Intravascular ultrasound elastography is a method for measuring the local elastic properties using intravascular ultrasound (IVUS). The elastic properties of the different tissues within the atherosclerotic plaque are measured through the strain. Knowledge of these elastic properties is useful for guiding interventional procedures (balloon dilatation, ablation) and detection of the vulnerable p...
متن کاملCoronary plaque classification with intravascular ultrasound radiofrequency data analysis.
BACKGROUND Atherosclerotic plaque stability is related to histological composition. However, current diagnostic tools do not allow adequate in vivo identification and characterization of plaques. Spectral analysis of backscattered intravascular ultrasound (IVUS) data has potential for real-time in vivo plaque classification. METHODS AND RESULTS Eighty-eight plaques from 51 left anterior desce...
متن کاملGlobal characterization of coronary plaque rupture phenotype using three-vessel intravascular ultrasound radiofrequency data analysis.
AIMS To compare the global characteristics of patients with and without evidence of plaque rupture (PR) in their coronary tree and to evaluate the phenotype of ruptured plaques using intravascular ultrasound (IVUS) radiofrequency data analysis (IVUS-VH). METHODS AND RESULTS Forty patients underwent three-vessel IVUS-VH interrogation. Twenty-eight PRs were diagnosed in 26 vessels (25.7% of the...
متن کاملStudy of atheromatous plaque using intravascular ultrasound.
T he increasing incidence of metabolic risk factors in the modern world makes it reasonable to predict that atheromatous cardiovascular disease will become the primary cause of death worldwide by 2020. An understanding of the factors that influence the natural history of atherosclerosis and its complications is essential for the future development of strategies for prevention and therapeutic in...
متن کاملOrbital Atherectomy Plaque Modification Assessment of the Femoropopliteal Artery Via Intravascular Ultrasound (TRUTH Study)
OBJECTIVE The Tissue Removal Assessment with Ultrasound of the SFA and Popliteal (TRUTH) study assessed the performance of the orbital atherectomy system (OAS) to treat femoropopliteal arteries, including determining its effect on plaque removal. METHODS Patients with symptomatic femoropopliteal peripheral arterial disease were treated with the OAS followed by adjunctive balloon angioplasty (...
