Summary: Randomized, open, pragmatic essay PROTECT (patient related outcomes of Endeavor versus Cypher stenting trial) compared two drug-eluting stents with different behaviors, (Cypher ® and Endeavor ®), in the reendothelialization degree and antiproliferative potency. Cypher has a permanent sirolimus-eluting polymer which generates a potent antiproliferative effect and a suboptimal healing (or reendothelialization). Furthermore, Endeavor has...

Background: Octogenarian patients represent an increasingly growing population. In addition, this age group has a higher proportion of co-morbidities with more extensive and complex coronary disease. However, they have often been excluded from major studies, whose average age is usually 60 years. Despite having a more complex coronary anatomy, the role of pharmacological stent (DES)...

Fundamentals. Background: Although we’ve had more than a decade of experience with implanting drug-eluting stents, (DES), the best treatment for restenosis on these devices remains unknown. The drug-eluting balloons are a promising alternative which avoid the possibility of a new layer of metal on the restenotic injury. This study compared the performance of these balls...

Summary: Second-generation drug-eluting stents have shown better results than their predecessors. In this study we compare two second-generation drug stents in patients with unprotected left coronary trunk injuries. Methods and results: 650 patients with unprotected trunk injury were randomized to either XIENCE V (everolimus eluting) or RESOLUTE (zotarolimus eluting) stents. The primary endpoint was the...

Asymmetrical expansion of the stent produces an uneven neointimal growth and increases the risk of thrombosis. The study was divided into two parts: the first one aimed at comparing, in the acute phase and the medium term, the result of provisional bifurcation stenting technique with sirolimus-eluting stent vs everolimus-eluting stent (both guided by IVUS); the...

Uncovered struts compromise re-endothelization and may induce thrombosis. The new stent approved in China and already used in more than 50,000 patients, is a sirolimus-eluting device with a bio-degradable polymer. Animal studies showed rapid and complete endothelialization. The study included 20 patients with stable angina randomized on a 1:1 ratio to receive, in the same...

This balloon expandable stent is combined with a guide 0.014 in its distal part. The platform is made of cobalt chrome and the polymer is bio-degradable. 30 patients were included prospectively and there was angiographic follow-up with IVUS and OCT after 6 months. The reference vessel diameter was 2.69 mm ± 0.48, with a length...

The study aims to evaluate clinical, angiographic and IVUS results of the new platinum chromium everolimus stent. The new design of the device has additional proximal connectors to enhance the longitudinal strength where distortion is more common. Included were 100 patients with de novo coronary lesions and a reference diameter of 2.5 to 4 mm...

This new device is a stainless steel platform of 120 µm thick with a sirolimus-eluting bio-absorbable polymer. It has two separate parts: a larger diameter proximal part and a smaller diameter distal part connected by two 1.2 mm structures. The objective of this study was to test (first in man) the device in bifurcations. We...

The ideal therapy for treating in-stent restenosis continues to be debated . The pharmacological balloons showed good results in this context, but no direct comparisons available of pharmacological balloonsversus second-generation DES.This prospective, multicenter randomized 189 patients with in-stent restenosis of conventional stents receiving pharmacological balloon or everolimusDES.The primary endpoint was angiographicat 9 months spotting a...
