Validation of Coronary Wire for the Acquisition of Intracoronary Electrocardiogram in Swine.

Background: We report the first in-literature animal experiment to validate the intracoronary ECG signal acquired from a coronary wire compared with the direct signal from an epicardial electrode.

Methods: An animal model study was performed in a 40 kg pig. Acute myocardial ischemia was induced by intracoronary balloon inflation for 60 s.

Intravascular ultrasound imaging in evaluation of aortic stiffness: A proof-of-concept study.

Background: Aortic stiffness is a well-known cardio-vascular risk factor. For years, different methods have been studied in the assessment of aortic elastic properties and large arterial stiffness for risk stratification. Herein is an assessment of the role of intravascular ultrasound (IVUS) imaging for the evaluation of aortic elastic properties.

Use of the Bifurcation Optimization Stent System in cardiological settings.

The bifurcation optimization stent system (BiOSS) LIM (Balton, Warsaw, Poland) stent is a dedicated coronary bifurcation stent. Its unique construction is developed in accordance with the anatomy of the coronary bifurcations, thus eliminating the carina displacement as a mechanism of side branch ostium compromise. Since its development in 2008, the BiOSS stent underwent several changes with the latest version created of sirolimus eluting cobalt-chromium stent.

Vertebral Artery Stenting in a Patient With Bow Hunter's Syndrome.

This report describes the case of a man with Bow Hunter's syndrome that was diagnosed by dynamic cerebral angiography. A decision for endovascular treatment was made. A self-expandable stent, 8 × 300 mm, was implanted in the left vertebral artery with excellent results, with resolution of the patient's symptoms and without any procedure-related complications.

Elliptical stretch as a cause of side branch ostial compromise after main vessel stenting in coronary bifurcations: New insights from numerical analysis.

Background: The side branch (SB) compromise after main vessel (MV) stenting remains a significant problem in coronary bifurcation treatment. Currently the two major hypotheses for the mechanism of SB compromise are carina shift from MV into the SB and plaque shift into the ostium of side vessel. It is proposed herein, SB ostial deformation leading to reshaping of the ostium from circle to ellipse is a third possible mechanism.
