Bioimpedance real-time charazterization of neointimal tissue inside stents [PDF]

, 2017
It is hereby presented a new approach to monitor restenosis in arteries fitted with a stent during an angioplasty. The growth of neointimal tissue is followed up by measuring its bioimpedance with Electrical Impedance Spectroscopy (EIS).

Excessive Ostial Stent Protrusion: Evaluation of Management Strategies and Clinical Outcomes of the Side Flap Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Backgrounds Accurate stent positioning in aorto‐ostial lesions remains challenging due to complex three‐dimensional anatomy, lack of optimal fluoroscopic projections, and high rates of geographic miss. Stent overhang impairs guide catheter re‐engagement and complicates future revascularization.

Timing of silicone stent removal in patients with post-tuberculosis bronchial stenosis

Annals of Thoracic Medicine, 2013
Context: In patients with post-tuberculosis bronchial stenosis (PTBS), the severity of bronchial stenosis affects the restenosis rate after the silicone stent is removed.

Advances in procedural techniques--antegrade. [PDF]

, 2014
There have been many technological advances in antegrade CTO PCI, but perhaps most importantly has been the evolution of the "hybrid' approach where ideally there exists a seamless interplay of antegrade wiring, antegrade dissection re-entry and ...

Successful Management of a Complex Coronary Bifurcation Lesion in Acute Coronary Syndrome Using a Free‐Metal Approach

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We present the case of a 56‐year‐old male with non‐ST elevation myocardial infarction (NSTEMI) and a complex thrombotic lesion at the ostial left circumflex artery (LCX), extending into bifurcating marginal branches. Due to the high risk of side branch occlusion, a stentless strategy using thrombus aspiration, the reverse wire technique, and ...

Impact of chronic outward force on arterial responses of proximal and distal of long superficial femoral artery stent

BMC Cardiovascular Disorders, 2021
Background Self-expanding nitinol stent (SENS) implantation is commonly oversized in the superficial femoral artery (SFA), and leads to chronic outward force (COF) and in-stent restenosis (ISR).

Dealing with in-stent restenosis [PDF]

Heart, 1998
Stents have been shown to reduce the incidence of restenosis; however, they are not a cure. In two trials the angiographic restenosis rate was reported to be between 20% and 30% (in the Benestent II trial the unpublished quoted restenosis rate was 15%). These trials were based on stenting short, de novo lesions, in native coronary arteries.

A Novel 3D Wiring Technique—ZOLUTION Zero Degree OverLap View Universal Three DimensIONal CTO Wiring

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We present a novel simple and easy‐to‐use 3D wiring technique for coronary chronic total occlusions (CTOs) named ZOLUTION—Zero OverLap View Universal Three dimensIONal wiring. ZOLUTION can be used for: (1) Distal cap puncture, (2) CTO body wiring, (3) Retrograde wiring, and (4) Reverse controlled antegrade and retrograde tracking (reverse CART)
