Ivus cardiology


— Use of IVUS to guide implantation of everolimus-eluting stents in long coronary lesions was associated with better outcomes than angiography-guided implantation, according to data presented at the American Heart Association Scientific Sessions. IVUS provides detailed and accurate measurements of lumen and vessel size, plaque area and volume, and the location of key anatomical landmarks. Abstract—Intravascular ultrasound (IVUS) is a valuable adjunct to angiography, providing new insights in the diagnosis of and therapy for coronary disease. But, IVUS is a highly operator dependent method and requires  REVIEW. percutaneous  Cardiology in Review: November/December 2016 - Volume 24 - Issue 6 - p 303–309.

Imaging. Myeong-Ki Hong, MD, PhD, and  With standard intravascular ultrasound (IVUS) full stent expansion was assessed (A, large arrow: stent-graft; small arrow: lumen), revealing a weak signal distal of the stent caused by partial absorption of the ultrasound signal from the specific stent graft material. IVUS after expansion after angiographic increase in minimal stent area angiographically guidance (CSA >60%of (MSA). Both guidelines advocated use of IVUS for stent optimization and for evaluation of the mechanism of stent failure. Intravascular Ultrasound (IVUS) is a catheter based system that allows physicians to acquire images of diseased vessels from inside the artery. We do coronary, peripheral, and structural procedures.
