OBJECTIVES The objective of this study was to identify clinical, lesional and procedural factors that can predict restenosis after coronary stent placement. BACKGROUND Coronary stent placement reduces the restenosis rate compared with that after percutaneous transluminal coronary angioplasty (PTCA). However, restenosis remains an unresolved issue, and identification of its predictive factors ...

Cardiovascular surgery had great advancement in the twentieth century. In 1929, Werner Forssman performed the first human cardiac catheterization on himself. Then cardiac catheterization gradually became a gold standard in the diagnosis of congenital heart diseases as well as valvular heart diseases. In 1953, Gibbon set a milestone for cardiac surgery by invention of cardiopulmonary bypass. Mas...

case presentation we present a case of a grade iii coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. conclusions the double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation. introduction coronary vessel perforation is one of the most feared complications of coronary a...

INTRODUCTION The aim of this study was to evaluate the medium-term clinical and angiographic results, as well as the occurrence and treatment of restenosis, following the implantation of sirolimus-eluting stents (SES) in patients undergoing coronary angioplasty. METHODS All patients who have an SES implanted in our department are entered into a database, with a view to evaluating the use of s...

Since the first percutaneous transluminal coronary angioplasty (PTCA) performed by Andreas Gruntzig in 1977 the technology has evolved significantly. Progress of PTCA has seen the development of many devices, some of which are still in use and many others that have fallen in disuse. The main limitation of the plain old balloon angioplasty (POBA) was the problem of elastic vascular recoil causin...

Background The American Heart Association has reported that coronary artery disease affects over 13 million people in the United States and is the number one cause of death in that country.1 Over the past 20 years, one of the more popular procedures for treating coronary artery stenosis has been percutaneous transluminal coronary angioplasty (PTCA). However, PCTA has some shortcomings, and in s...

Safety and efficacy concerns regarding elective coronary artery surgery in patients with prior coronary stents Recent data have raised concerns about the safety of drug-eluting stents. 1 Stents are used in over 70% of percutaneous coronary interventions (PCIs) because they reduce the risk of acute major complications of PCI and long-term restenosis. Despite the low procedural morbidity afforded...

OBJECTIVES The purpose of this study was to evaluate the approach of intravascular ultrasound (IVUS)-guided percutaneous transluminal coronary angioplasty (PTCA) with spot stenting (SS) for the treatment of long coronary lesions. BACKGROUND Treating long coronary lesions with balloon angioplasty results in suboptimal short- and long-term outcomes. Full lesion coverage with traditional stentin...

2015 Since the introduction of plain old balloon angioplasty, there have been several improvements in the treatment of coronary artery disease, with the advent of bare metal stents and drug-eluting stents being two notable milestones. Although these stents confer better acute gains in coronary interventions, the risk of instent restenosis (ISR) remains, especially with bare metal stents. Hence,...
