Vulnerable atherosclerotic plaque comprises a lipid-rich necrotic core, covered by a thin fibrous cap, that is weakened by macrophage infiltration.1 Plaques that have this morphology and composition have a greater probability of being associated with acute coronary syndromes in clinical studies.2,3 Coronary artery disease is most commonly triggered by the rupture of vulnerable plaque and…

Intravascular ultrasound (IVUS) is the first catheter-based imaging modality that has been widely used in interventional cardiology.1 It creates cross-sectional images of the vessel lumen and the arterial wall and provides valuable diagnostic information to angiography regarding lumen and vessel measurements and plaque morphology. This information helps clinical decision-making in ambiguous…

Intracoronary imaging is able to aid the interventional cardiologist in the characterisation of atherosclerotic plaque morphology, in optimising stent sizing, and in minimising the complications associated with percutaneous coronary intervention (PCI). Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are commonly used methods, while newer spectroscopic methods are under…

Coronary angiography has been the gold standard technique for evaluating coronary arterial disease for the past 50 years. Increasingly, however, realisation of the limitations of coronary angiography, mainly the inability to supply information regarding the coronary wall, has prompted the design and development of adjunctive technologies to better evaluate not just luminal disease but also the…

The amount of coronary artery calcification increases with age and the presence of cardiovascular risk factors and comorbidities.1,2 Up to 20% of percutaneous coronary intervention (PCI) procedures are challenged by severe calcifications, and coronary calcifications have been shown to be an independent predictor of PCI failure and future adverse cardiac events.3,4 Lesion calcification increases…

Detection of obstructive disease of the left main coronary artery (LMCA) is relatively unusual in the catheterisation laboratory, as it accounts for approximately 4 % of all coronary angiograms, with isolated LMCA disease observed in only 5–10 % of these cases.1
Intervention to the LMCA is, however, notable compared to the treatment of coronary stenosis elsewhere in the coronary tree. First,…

Introduction
Intravascular ultrasound (IVUS) has enhanced our understanding of atherosclerotic plaque morphology, and provides a unique opportunity to guide cardiovascular interventions and evaluate the results of these interventions. IVUS is safe, cost efficient and effective in guiding clinical decisions and cardiovascular interventions and improves outcomes when used during coronary artery…
