1. Various Types of Plaque Disruption in Culprit Coronary Artery Visualized by Optical Coherence Tomography in a Patient With Unstable Angina

   jstage.jst.go.jp (Nov 17 2008) Cardiology Explore Article

   A 58-year-old man underwent cardiac catheterization for unstable angina. The coronary angiogram revealed severe stenosis of the right coronary artery. Although 20-MHz, phased-array intravascular ultrasound (IVUS) only visualized eccentric, low echoic plaque at the culprit site, optical coherence tomography (OCT) clearly revealed ruptured plaque and an intraluminal thrombus. OCT also revealed a small ruptured plaque and an eroded plaque with intraluminal thrombi in a distal site remote from the culprit ... (Read Full Article)

2. Delayed Endothelialization After Polytetrafluoroethylene-Covered Stent Implantation for Coronary Aneurysm

   jstage.jst.go.jp (Nov 17 2008) Cardiology Explore Article

   A polytetrafluoroethylene (PTFE)-covered stent is specially used to treat coronary perforation complicating percutaneous intervention in order to prevent the aneurysm from rupturing, but until now it has not been known if endothelialization occurs inside this type of stent. A patient with a giant aneurysm of the right coronary artery underwent successful implantation of a PTFE-covered stent. Angiography at 9-month follow-up showed focal restenosis at the proximal edge of the stent ... (Read Full Article)

3. Safety and Usefulness of Non-Occlusion Image Acquisition Technique for Optical Coherence Tomography

   jstage.jst.go.jp (Sep 1 2008) Cardiology Explore Article

   Background Because optical coherence tomography (OCT) requires balloon-occlusion to overcome image attenuation by blood, the present study investigated the safety and usefulness of a new non-occlusive technique. Methods and Results The 40 angina patients were assigned to the continuous-flushing method or the balloon-occlusion method group. The continuous-flushing method was superior for observing proximal lesions compared with the balloon-occlusion method (94% vs 55%, p=0.01). There were no differences between groups in ...

4. From Bench to Bedside - A Novel Technique of Acquiring OCT Images

   jstage.jst.go.jp (Apr 29 2008) Cardiology Explore Article

   Background Optical coherence tomography (OCT), a high resolution intravascular imaging technique, requires blood displacement for reliable image acquisition and the current technique uses a soft occlusion balloon plus saline injection in the coronary artery. A non-occlusive technique based on manual infusion of a viscous iso-osmolar solution has been developed and tested and validated through a 2-phase study. Methods and Results OCT assessment was performed with the M2 LightLab OCT (LightLab ... (Read Full Article)

5. Heavily Calcified Coronary Lesions Preclude Strut Apposition Despite High Pressure Balloon Dilatation and Rotational Atherectomy

   jstage.jst.go.jp (Dec 27 2007) Cardiology Explore Article

   Heavily calcified lesions (HCL) continue to present challenges that are not always solved by modern low-profile, non-compliant high-pressure balloons, or bladed balloons. Uncrossable or unexpandable lesions need lesion modification, using ablating devices such as rotational atherectomy. Three cases of HCL treated with drug-eluting stents, using a new intravascular imaging device, Optical Coherence Tomography with 10-fold superior resolution and fewer artifacts compared with conventional intravascular ultrasound, are presented. Insights from using ... (Read Full Article)
