background: the drug-eluting stent (des) decreases the rate of coronary restenosis and re-obstruction. the aim of this study was to assess prospectively the effectiveness of the new generation des on the left ventricular (lv) systolic and diastolic functions in patients with isolated severe proximal left anterior descending (lad) coronary artery stenosis. methods: a prospective study was conduc...

This case demonstrates the possibility of using balloon angioplasty in patients with non-ST segment elevation acute coronary syndrome and restenosis previously implanted stents as a measure to temporary stabilize blood flow patient’s condition for preoperative preparation subsequent emergency bypass grafting.

L esions located at coronary artery bifurcations represent one of the challenging areas in interventional cardiology. The use of coronary stents has resulted in a higher angiographic success rate compared to balloon angioplasty. Angiographic restenosis rates nevertheless remain high for the various techniques that employ bare metal stents. Although the advent of drug-eluting stents (DES) holds ...

CONTEXT In patients with de novo coronary lesions, drug-eluting stents have drastically reduced restenosis risk compared with bare metal stents and conventional balloon angioplasty. It is less clear whether drug-eluting stents are superior to conventional balloon angioplasty for the treatment of patients with in-stent restenosis. OBJECTIVES To assess if drug-eluting stents are a more effectiv...

INTRODUCTION Coronary angioplasty with stenting has revolutionized the treatment of coronary artery disease. This article describes the history of coronary angioplasty and stenting, reviews the contemporary stents and recommendations and highlights the on-going work and potential future directions. SOURCES OF DATA This review examined the data on coronary stents available in PubMed. AREAS O...

Over the past decade, the use of endoluminal metallic stents has become common practice during percutaneous coronary intervention (PCI), especially after clinical trials showed evidence of decreased restenosis rates when compared with balloon angioplasty alone.1–3 Although stents significantly reduce restenosis when compared with balloon angioplasty, restenosis rates in patients who receive ste...

INTRODUCTION In this study we present our findings from a series of patients who underwent coronary angioplasty and implantation of drug-eluting stents with rapamycin or paclitaxel. METHODS Two hundred and twenty-three consecutive patients with 343 coronary lesions underwent angioplasty with implantation of 220 rapamycin-eluting stents (Cypher) and 297 paclitaxel-eluting stents (Taxus). RES...

The introduction of the coronary stent in 1986 remains the only real asset to balloon angioplasty introduced about 10 years earlier. Unfortunately, the undeniable advantages of stenting in terms of preventing abrupt closure and reducing restenosis are not fully exploited. The prognostic benefit to be expected from judicious stenting has been given up by default stenting. Infarctions and lives s...

Coronary stents were developed to overcome the two main limitations of balloon angioplasty, acute occlusion and long-term restenosis. Coronary stents can tack back intimal flaps and seal the dissected vessel wall, thereby treating acute or threatened vessel closure after unsuccessful balloon angioplasty. After successful balloon angioplasty, stents can prevent late vessel remodeling (chronic ve...
