Acute Myocardial Infarction Caused by Distal Embolization From a Proximal Ruptured Plaque

JACC: Case Reports, 2020
Generally, in acute myocardial infarction, the plaque rupture site is around the occluded site. In this case, coronary angioscopy effectively detected a rupture at a nonstenotic lesion, and the consequent thrombotic occlusion may lead to acute myocardial

Catheter pose-dependent virtual angioscopy images visualized on augmented reality glasses

Current Directions in Biomedical Engineering, 2019
Fluoroscopy and digital subtraction angiography provide guidance in endovascular aortic repair (EVAR) but introduce radiation exposure and require the administration of contrast agent. To overcome these disadvantages, previous studies proposed to display

Optical endovascular imaging combining endoscopy, NBI and OCT, a feasibility study

Current Directions in Biomedical Engineering, 2019
For imaging of the vascular structure, angiography is state of the art. This can be done by contrast enhanced XRay, CT or MR imaging. But these modalities typically only show the blood flow and do not allow a depiction of the vasculature itself.

In vivo coronary angioscopy

Journal of the American College of Cardiology, 1983
The feasibility of in vivo coronary angioscopy was tested utilizing a 1.8 mm angioscope in vessels where blood had been replaced by optically clear liquids, including a new perfluorocarbon emulsion. After trials in postmortem canine and human coronary arteries, in vivo intraluminal visualization was accomplished in the dog with a catheterization ...
