BACKGROUND AND PURPOSE To assess the benefits of carotid artery stenting before coronary artery bypass surgery to reduce the risk of stroke occurring during the cardiac procedure. METHODS A prospective cohort study was performed in patients undergoing carotid artery stenting before coronary artery bypass surgery, or combined bypass and valve replacement procedures, to assess the procedures ef...

BACKGROUND Randomized studies have shown that the use of coronary-artery stenting as the initial treatment for coronary stenosis is associated with a lower risk of restenosis than is standard coronary angioplasty. We prospectively investigated the efficacy of these two approaches in selected patients with isolated stenosis of the proximal left anterior descending coronary artery. METHODS A to...

Coronary arteriography revealed significant left anterior descending coronary artery stenosis in a 72-year-old man with a history of myocardial infarction. Stenting of the stenotic vessel was performed. Twelve hours after stenting the patient complained of chest pain but emergent coronary arteriography did not show sign of any coronary arterial stenosis. Under suspicion of coronary thrombus for...

Catheter induced left main coronary artery dissection is a rare but well recognized life threatening complication of coronary angiography and angioplasty. We present a case of left main coronary artery dissection induced with a guide catheter while dealing with chronic total occlusion (CTO) and bailout stenting of left main and Left anterior descending (LAD) artery.

Coronary stent fracture is an uncommon complication of stent implantation. We report a case of 66 yrs old male patient presented with unstable angina who underwent stenting in right coronary artery 3 months ago. Computed Tomography Coronary angiogram revealed complete type V stent fracture with pseudoaneurysm formation in right coronary artery. This was managed by surgical revascularization by ...

The purpose of this study was to compare the clinical outcomes and costs of coronary stenting with conventional percutaneous transluminal coronary angioplasty (PTCA) in patients with coronary artery disease (CAD) in Japan. The increasing use of stent implantation in CAD has raised economic concerns for healthcare decision makers. This decision analysis model, which applies to the Japanese healt...

The in-stent restenosis may still occur in patients with a coronary bifurcation stenting. purpose of this study is to investigate the effect relationships between angles artery and three types stenting techniques (T-stenting, Culotte, Kissing techniques), for comparing two kinds arterial shapes using computational fluid dynamics (CFD) analysis. finite element models arteries were reconstructed ...

Surgical treatment of simultaneous coronary and carotid disease is still controversial, because of the high risk of morbidity and mortality after combined or staged carotid artery endoarterectomy and the coronary artery bypass grafting approach. We report the first 10 patients with concomitant coronary and carotid disease successfully treated with an alternative strategy consisting of simultane...

INTRODUCTION AND OBJECTIVES Percutaneous coronary intervention for coronary bifurcations is usually associated with a low success rate, a high rate of complications, and a more frequent need for target lesion revascularization. The aim of this prospective study was to evaluate immediate and medium-term clinical and angiographic outcomes after the application of crush T stenting. METHODS This ...

Periprocedural intravascular ultrasonography guidance for left main coronary artery stenting is well established. However, the role of this tool is also important at follow-up interventions. We present a case of a patient with previous history of left main coronary artery angioplasty. During a recent attempt to treat tight stenosis in the left anterior descending coronary artery, it was not pos...
