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…

In the bare metal stent (BMS) era, several intravascular ultrasound(IVUS) studies have validated the strategy of reducing in-stent restenosis rates by a strict adherence to an optimal stent implantation technique, predominantly by avoiding stent underexpansion.1 In a first phase after the introduction of drug-eluting stents(2003), the spectacular reduction in restenosis rates, based on…

Incomplete stent apposition (ISA) or stent malapposition is the lack of contact between stent struts and the underlying arterial wall. ISA has been associated with significantly higher levels of thrombus deposition1 and is typically assessed by intravascular imaging techniques such as optical coherence tomography (OCT) and intravascular ultrasound (IVUS).2–4 These imaging modalities are useful to…

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…

Diffuse Coronary Stenosis
A diffuse coronary stenosis is customarily defined as any stenosis exceeding 20 mm in length in the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines and the Society for Cardiovascular Angiography and Interventions (ACCF/AHA/SCAI) guidelines for PCI.6 This cut-off value has not been used in trials of diffuse…

The coronary tree is comprised of arteries which divide into ever smaller branches to supply the myocardium. This means that the diameter of the vessel proximal to a bifurcation is always larger than the diameter of the main vessel distal to the bifurcation. The proximal optimisation technique (POT) was proposed by Dr Olivier Darremont as a technique to compensate for this difference in diameters…

Much has been said about the allegedly final frontiers in interventional cardiology. Is it long-term outcome regarding percutaneous coronary intervention (PCI) for multivessel coronary artery disease? Is it the safety and efficacy of PCI versus coronary artery bypass grafting in patients with diabetes? There is definitely a movement within the interventional cardiology community that says it is…
