Introduction Intravascular ultrasound (IVUS) can resolve abnormalities within the coronary artery to a degree that is not possible with angiography alone. With an axial resolution of 70-200 μm and lateral resolution of 200-400 μm, IVUS can provide information on arterial wall and luminal composition that can change clinical management decisions. This document describes scenarios of clinical… View more

RC Webinars: Intravascular ultrasound guided management of diffuse stenosis
Author(s): Javier Escaned Added: 5 years ago
Diffuse stenoses present a unique set of challenges related to accurate vessel sizing in the setting of remodelling, the identification of disease in segments that appear angiographically normal and achievement of optimal stent implantation both in terms of luminal dimensions and stent apposition. As the absence of a well-defined workflow has likely hampered more widespread uptake of… View more

Background Incomplete stent apposition (ISA) is defined as a separation of at least one stent strut from the vessel wall, not related with a side branch. The relevance of this phenomenon derives from intravascular ultrasound (IVUS) studies suggesting a potential relationship between ISA and stent thrombosis. The mechanism by which ISA can contribute to stent thrombosis remains unknown, but it has… View more

Introduction Previous studies proved that fractional flow reserve (FFR)-guided decision-making in general coronary lesions can reduce unnecessary revascularisation and improve patient outcomes.1 Compared to non-bifurcation lesions, bifurcation lesions are associated with more complex procedures, less procedural success and worse clinical outcomes. It is clinically important to accurately assess… View more

Many experts would agree that the concept of looking at vessel architecture from the inside using intracoronary probes, instead of simply relying on the angiographic vessel cast, is an elegant way to practise interventional cardiology in order to decide whether to treat a coronary artery and to guide coronary intervention. The historical development of stents neatly exemplifies this notion: the… View more

A50-year-old asymptomatic physician referred himself for coronary computed tomography angiography (CTA) because of an elevated low-density lipoprotein (LDL) of 120. His high-density lipoprotein (HDL) was 42. Triglycerides, high-sensitivity C-reactive protein (hsCRP), glucose, and vitamin D levels were normal. He exercised regularly on an elliptical trainer without chest pain or unusual shortness… View more
