Coronary artery stents revolutionized the practice of interventional cardiology after they were
first introduced in the mid-1980s. Since then, there have been significant developments in …

The ACC/AHA Task Force on Practice Guidelines was formed to gather information and

Objectives: This study sought to establish a model for grading lesion difficulty in
interventional chronic total occlusion (CTO) treatment. Background: Owing to uncertainty of …

In patients with stable CAD, PCI can be considered a valuable initial mode of
revascularization in all patients with objective large ischaemia in the presence of almost …

Any definition of coronary CTO must consider the degree of lumen narrowing, antegrade
blood flow grade, and age of the occlusion. CTOs are characterized by significant …

At present, 90 to 95 percent of percutaneous coronary interventions involve the implantation
of a stent, often a drug-eluting stent, though most published data originated in the era of bare …

In a registry analysis of 8,004 consecutive patients presenting for diagnostic catheterization
at a single institution from 1990 to 2000, chronic total occlusion (CTO) was found in 52% of …

Objectives: Our aim was to investigate in-hospital outcomes of percutaneous coronary
intervention (PCI) of chronic total occlusion (CTO) using contemporary techniques …

Abstract Aims Chronic total occlusions (CTOs) are commonly found on diagnostic
angiography, and there is some evidence from one study that successful percutaneous …
