OBJECTIVES This study sought to establish a model for grading lesion difficulty in interventional chronic total occlusion (CTO) treatment. BACKGROUND Owing to uncertainty of success of the procedure and difficulties in selecting suitable cases for treatment, performance of interventional CTO remains infrequent. METHODS Data from 494 native CTO lesions(More)
The use of directional coronary atherectomy (DCA) in current practice has been limited. The SilverHawk System is a newly developed plaque excision device that aims to overcome the drawbacks of prior DCA platforms. The device was evaluated in a porcine coronary model and in a series of patients. Procedural variables along with outcomes were reviewed.(More)
OBJECTIVE To present results of a registry of a novel vascular access device. BACKGROUND Arterial access has been largely unchanged for 60 years. The Arstasis device creates a novel shallow-angle arterial access designed to facilitate hemostasis without use of a vascular closure device (VCD) or implantation of a foreign body for closure. This is the first(More)
OBJECTIVES Our aim was to investigate in-hospital outcomes of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) using contemporary techniques. BACKGROUND Despite its increasing popularity and technical complexity, clinical outcomes of PCI for CTO using contemporary techniques have not been adequately evaluated. METHODS The J-CTO(More)
AIMS We investigated the impact of the J-CTO score, a pre-procedural risk score for successful guidewire crossing within 30 minutes through chronic total occlusion (CTO) lesions, on procedural and midterm clinical outcomes in terms of target lesion revascularisation (TLR) after CTO recanalisation. METHODS AND RESULTS The primary endpoint of this substudy(More)
More than 20 years have passed since percutaneous transluminal coronary angioplasty (PTCA) was introduced for the treatment of coronary artery disease. During the first decade, PTCA outcome had improved significantly. However, acute occlusive complications and restenosis remained as significant limitations of the procedure. During the second decade, new(More)
OBJECTIVES Using intravascular ultrasound (IVUS) and histology, the purpose of this study was to evaluate the occurrence of arterial wall overstretch and Dotter effect following revascularization with a plaque excision (PE) catheter compared with balloon angioplasty. BACKGROUND Previous studies have demonstrated the safety and feasibility of plaque(More)
On the basis of animal models of arterial injury, smooth muscle cell proliferation has been posited as a dominant event in restenosis. Unfortunately, little is known about this proliferation in the human restenotic lesion. The purpose of this study was to determine the extent and time course of proliferation in primary and restenotic coronary(More)
