Is rotational atherectomy here to stay?

Rotational atherectomy was developed to ablate selectively inelastic atherosclerotic plaque, while deflecting normal arterial wall away from the rotating burr. Intravascular ultrasound (IVUS) studies have confirmed that rotablation differentially removes even hard, calcified plaque without damaging normal arterial wall. Early in clinical experience, the ability to ablate previously undilatable ...

Covert Channels | Here to Stay? Covert Channels | Here to Stay?

We discuss the di culties of satisfying high-assurance system requirements without sacri cing system capabilities. To alleviate this problem, we show how trade-o s can be made to reduce the threat of covert channels. We also clarify certain concepts in the theory of covert channels. Traditionally, a covert channel's vulnerability was measured by the capacity. We show why a capacity analysis alo...

Rotational atherectomy: an Update

As we known, drug-eluting stents (DES) reduce the risk of restenosis and represent an important advance in coronary intervention. Newer-generation DES with thin struts releasing limus-family drugs from durable or biodegradable polymers have further improved clinical outcomes, as compared with early-generation DES releasing sirolimus or paclitaxel. The risk of stent thrombosis has become exceedi...

Rotational atherectomy: Technical update.

Percutaneous coronary intervention is currently the most common form of revascularization for symptomatic coronary artery disease. In elderly, diabetic and renal patients, there is an increased prevalence of calcified coronary disease. Rotational atherectomy (RA) can be useful in the treatment of these lesions. Plaque removal was initially proposed as an alternative to balloon angioplasty, henc...
