Direct Intravascular Observation of Trifecta️ Bioprosthetic Valve Dysfunction Using Nonobstructive General Angioscopy [PDF]

Case Reports in Cardiology
Although surgical reintervention remains the standard of care for failed surgical valves, transcatheter aortic valve implantation in surgical aortic valves (TAV-in-SAV) has emerged as a viable alternative with reliable results.

Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

In vivo coronary angioscopy [PDF]

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The feasibility of in vivo coronary angioscopy was tested utilizing a 1.8 mm angioscope in vessels where blood had been replaced by optically clear liquids, including a new perfluorocarbon emulsion.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 ...

Coronary angioscopy. [PDF]

Texas Heart Institute journal, 1995
Coronary angioscopy will not replace angiography as the gold standard for imaging atherosclerotic coronary arteries. However, there may well be a clinical niche for a technology that gives accurate information regarding a specific lesion, if that information can be used to improve the acute or chronic outcome of an interventional procedure.

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

Safety and feasibility of dual antiplatelet therapy termination guided by angioscopic findings 6 months after flow diverter placement [PDF]

Frontiers in Neurology
BackgroundFlow diverters (FDs) are commonly used to treat intracranial aneurysms with wide necks. Dual antiplatelet therapy (DAPT) is essential during the perioperative period to prevent thrombosis; however, it increases the risk of hemorrhagic ...

Serial Change and Clinical Impact of Irregular Protrusion in Lesions With Chronic Coronary Syndrome. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background The changes over time and effects on long‐term clinical outcomes beyond 1 year of irregular protrusion (IP) in chronic coronary syndrome (CCS) remains unclear. Aims This study aimed to assess the time‐dependent change and long‐term clinical impact of IP in CCS lesions.
