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.

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 ...

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 ...

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
