Clinical Experience of a Novel Optical Coherence Tomography-Guided Coronary Chronic Total Occlusion Re-Entry Device.

We demonstrated a first-in-human case of successful antegrade dissection and re-entry using an image-guided re-entry catheter that enables real-time high-resolution visualization with graphical augmentation, and precision steering and advancement of a guidewire. The total time from over-the-wire deployment in the proximity of the distal cap to successful re-entry was <20 minutes. ().

Association between J-CTO score and long-term target lesion revascularization rate after successful chronic total coronary occlusion angioplasty (from the J-CTO Registry).

Objectives: The aim of this study was to evaluate the impact of the J-CTO score on long-term target lesion revascularization (TLR) after successful native chronic total occlusion (CTO)-percutaneous coronary intervention (PCI).

Background: We previously reported that the J-CTO score could be used to stratify the lesion complexity and procedural success rate in CTO lesions.

Methods: We evaluated the prognostic significance of a high J-CTO score for long-term TLR rate in the J-CTO Registry.

Impact of J-CTO score on procedural outcome and target lesion revascularisation after percutaneous coronary intervention for chronic total occlusion: a substudy of the J-CTO Registry (Multicentre CTO Registry in Japan).

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 was midterm TLR. The net midterm success rate was calculated by multiplying the lesion success rate by the TLR-free survival rate.

Use of a novel access technology for femoral artery catheterization: results of the RECITAL trial.

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.

Predicting successful guidewire crossing through chronic total occlusion of native coronary lesions within 30 minutes: the J-CTO (Multicenter CTO Registry in Japan) score as a difficulty grading and time assessment tool.

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 were analyzed.

In-hospital outcomes of contemporary percutaneous coronary intervention in patients with chronic total occlusion insights from the J-CTO Registry (Multicenter CTO Registry in Japan).

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 registry (multicenter CTO registry in Japan) is a large scale, multicenter registry enrolling consecutive patients undergoing PCI for CTO from 12 Japanese centers.

Mechanism of luminal gain with plaque excision in atherosclerotic coronary and peripheral arteries: assessment by histology and intravascular ultrasound.

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 excision for the treatment of de novo coronary and peripheral atherosclerotic disease. However, whether mechanical vessel dilatation related to catheter insertion contributes to gains in the final luminal diameter is uncertain.

Early experience with a novel plaque excision system for the treatment of complex coronary lesions.

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.
