Strokes are frequently devastating events with potentially fatal complications and significant disability, resulting in a major impact on the affected individual’s quality of life. It is well accepted that the presence of carotid stenosis is responsible for 20–30% of strokes.1 Great effort has therefore been invested in the search for treatments to reduce the stroke risk attributed to it… View more

For a period of over a decade, from the advent of bare-metal stents, culminating with the triumph of drug-eluting stents, interventional cardiology had a virtually unbroken winning streak. However, in 2006,… View more

Stroke is one of the most devastating complications after CABG surgery, entailing permanent disability and a 3–6 fold increased risk of death with a case-fatality rate up to 20 %.1,2 It is also associated with… View more

It is estimated that there are over 700,000 new cases of stroke each year in the US, of which 20–30% are thought to be secondary to carotid thromboembolic disease.1 In the last few years, carotid artery stenting (CAS) has significantly expanded as an alternative treatment to the conventional surgical carotid… View more

Renal artery stenosis (RAS) is a common manifestation of atherosclerotic disease. Although the exact prevalence rate for the population as a whole is unknown, RAS is seen in a significant proportion of patients who present with another manifestation of atherosclerosis (Table 1).1–7 Despite this high degree of prevalence, the management of RAS, specifically the role of revascularisation, remains… View more
