[Series] Intravascular imaging in coronary artery disease

The Lancet - Sa, 19/08/2017 - 00:00
Although it is the method used by most interventional cardiologists to assess the severity of coronary artery disease and guide treatment, coronary angiography has many known limitations, particularly the fact that it is a lumenogram depicting foreshortened, shadowgraph, planar projections of the contrast-filled lumen rather than imaging the diseased vessel itself. Intravascular imaging—intravascular ultrasound and more recently optical coherence tomography—provide a tomographical or cross-sectional image of the coronary arteries.

[Series] Update on antithrombotic therapy after percutaneous coronary revascularisation

The Lancet - Sa, 19/08/2017 - 00:00
For relief of coronary obstruction, percutaneous coronary intervention has become a standard-of-care procedure over the past 40 years. Nonetheless, optimal outcomes after coronary stenting require careful attention to antithrombotic therapy. This review aims to summarise the current available evidence and discusses how to integrate scientific knowledge into clinical decisions. In recent years, improvement and modifications of drugs and devices have changed the field tremendously, and substantially benefitted patient outcomes.
