Elective stenting of unprotected left main coronary artery stenosis: Effect of debulking before stenting and intravascular ultrasound guidance

TL;DR: A primary challenge in the development of clinical practice guidelines is keeping pace with the stream of new data on which recommendations are based as discussed by the authors, and the American College of Cardiology Foundation/American Heart Association (ACCF/AHA) is to respond promptly to new evidence.

TL;DR: Sirolimus-eluting stent implantation for unprotected LMCA stenosis appears safe with regard to acute and midterm complications and is more effective in preventing restenosis compared to BMS implantation.

TL;DR: Intravascular ultrasound imaging is a new method in which high resolution images of the arterial wall are obtained with use of a catheter placed within an artery, and an excellent correlation was obtained with those calculated from microscopic slides.

TL;DR: The results indicate that high-quality intravascular ultrasound images under controlled in vitro conditions can provide accurate microanatomic information about the histological characteristics of atherosclerotic plaques.

TL;DR: Although elective angioplasty of an unprotected LM coronary artery is technically feasible, the long-term prognosis of such patients is very poor, and LM angiopLasty in this subgroup should be reserved for patients in whom surgical revascularization is not an option.
