Clinical impact of intravascular ultrasound‐guided balloon angioplasty in patients with chronic limb threatening ischemia for isolated infrapopliteal lesion

Catheterization and cardiovascular interventions, 2020
To estimate the impact of intravascular ultrasound (IVUS) in patients with chronic limb‐threatening ischemia (CLTI) who underwent balloon angioplasty for isolated infrapopliteal lesion.

Clinical relevance of adding intravascular ultrasound to coronary angiography for the diagnosis of extrinsic left main coronary artery compression by a pulmonary artery aneurysm in pulmonary hypertension

Catheterization and cardiovascular interventions, 2020
We sought to assess the clinical value of adding intravascular ultrasound (IVUS) evaluation to coronary angiography (CA) to guide extrinsic left main coronary artery (LMCA) compression diagnosis and treatment in pulmonary hypertension (PH).

Intravascular ultrasound elastography: an overview

Ultrasonics, 2002
The composition and morphology of the atherosclerotic lesion are currently considered more important determinants of acute coronary ischemic syndromes than the degree of stenosis. When a lesion is unstable, it may rupture and cause an acute thrombotic reaction. A rupture prone plaque contains a large lipid pool covered by a thin fibrous cap. The stress

New developments in intravascular ultrasound

Vascular Medicine, 1998
Intravascular ultrasound (IVUS) is a dynamic imaging modality that provides real-time in vivo visualization of atherosclerosis and other vascular pathology. The tomographic image presentation of IVUS permits detailed assessment of plaque morphology and its corresponding responses to interventional therapy.

Intravascular ultrasound

Techniques in Vascular and Interventional Radiology, 2001
Intravascular ultrasound imaging, in which a catheter-based miniature sonographic transducer is introduced into vessels, provides high-resolution, cross-sectional, real-time imaging of the vessel wall and lumen. It has been found to be useful as both a diagnostic and therapeutic adjunct in the evaluation and management of various arterial and venous ...

Intravascular Ultrasound for Transvenous Interventions [PDF]

Techniques in Vascular and Interventional Radiology, 2013
Since the development of intravascular ultrasound in the late 1980s, the modality has been used both to image the vascular system and to direct interventions in target vessels. Intravascular ultrasound (IVUS) was initially used to image atherosclerosis and aid in its treatment, but it has more recently been employed within the venous system, allowing ...

Intravascular Imaging With Ultrasound

SPIE Proceedings, 1988
One of the major unresolved problems in the development of laser angioplasty is in monitoring the process of plaque ablation in real-time to provide the necessary operator feedback. As part of a project to test the feasibility of intravascular imaging with ultrasound we have developed, constructed, and tested a 20 MHz transmitter/receiver which can ...

Intravascular ultrasound, optical coherence tomography, and fractional flow reserve use in acute myocardial infarction

Catheterization and cardiovascular interventions, 2019
There are limited data on the use of intravascular ultrasound (IVUS), optical coherence tomography (OCT), and fractional flow reserve (FFR) during acute myocardial infarction (AMI).

Intravascular Ultrasound Applications

2000
Intravascular ultrasound (IVUS) has been available for clinical use for many years.1 Despite its success in both diagnostic and therapeutic situations,2–8 its applications have been very limited. This apparent lack of enthusiasm for IVUS is based, in part, on the initial cost of purchasing the equipment and the recurrent expense of ultrasound probes ...
