Bifurcation lesions account for 15–20% of all percutaneous coronary intervention (PCI) cases performed, representing about half a million cases annually.1 But PCI treatment for bifurcation coronary disease has historically yielded less satisfactory results than conventional stenting. The procedure is often technically challenging and has been associated with both lower procedural success rates… View more

Bifurcation lesions account for approximately 20–30% of all percutaneous coronary interventions (PCIs). Coronary bifurcation sites are prone to developing obstructive atherosclerotic disease due to turbulent blood flow and change of shear stress. With the complexity of bifurcation lesions, several classification systems have been advocated in order to extablish percutaneous strategies.1–3 In fact… View more

Transcatheter aortic valve implantation (TAVI) has undergone tremendous technological advancements since the first successful implantation in 2002 for symptomatic severe aortic valve stenosis (AS).1 It is currently considered as the standard of care for severe AS patients who have high surgical risk or may be deemed unsuitable for surgery.2 Broadly, there are two main categories of transcatheter… View more

Coronary artery stenting has evolved substantially since the first use of coronary stenting as an adjunct to balloon angioplasty in the early 1990s. The performance (and particularly the deliverability) of coronary stents has improved such that coronary stenting is now the primary mode of revascularisation for percutaneous coronary interventions in more than 95% of cases. Although stent delivery… View more

A bifurcation lesion within the coronary arterial circulation is defined as a stenosis occurring at, or adjacent to, a significant division of a major epicardial coronary artery.1 Bifurcation lesions account for 1–20% of all percutaneous coronary interventions (PCIs), and treatment remain technically challenging despite advances in PCI techniques and third-generation drug-eluting stent (DES)… View more

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… View more

An Introduction to Radiation X-rays, so-called because their nature was at the time unknown, were discovered by the German physicist Wilhelm Roentgen in 1895, one year before the discovery of ‘natural’ radioactivity by Henri Becquerel.1 X-rays found application in radiography a few years after their discovery, although the first side effect attributed to radiation injury (depilation) had been… View more

Patient Selection and Procedural Considerations for Coronary Orbital Atherectomy System

From the early days of percutaneous coronary intervention (PCI) it became apparent that the presence of severe coronary calcification was a predictor of worse clinical outcomes. In the era of plain old balloon angioplasty, severe coronary calcification was associated with an increased risk of coronary dissection and procedural failure, while in the bare-metal stent era, it was associated with a… View more
