Feasibility, reproducibility and characteristics of coronary bifurcation type assessment by three-dimensional optical coherence tomography

PLoS ONE, 2022
Aim To investigate the characteristics of coronary artery bifurcation type (parallel or perpendicular type) using three-dimensional (3D) optical coherence tomography (OCT), and determine the feasibility, reproducibility, assessment time and correlation ...

Cluster Oscillation of a Fractional-Order Duffing System with Slow Variable Parameter Excitation

Fractal and Fractional, 2022
The complicated dynamic behavior of a fractional-order Duffing system with slow variable parameter excitation is investigated. The stability and bifurcation behavior of the fast subsystem are analyzed by using the dynamic theory of fractional-order ...

OCT or Angiography Guidance for PCI in Complex Bifurcation Lesions.

New England Journal of Medicine, 2023
BACKGROUND Imaging-guided percutaneous coronary intervention (PCI) is associated with better clinical outcomes than angiography-guided PCI. Whether routine optical coherence tomography (OCT) guidance in PCI of lesions involving coronary-artery branch ...

The European bifurcation club Left Main Coronary Stent study: a randomized comparison of stepwise provisional vs. systematic dual stenting strategies (EBC MAIN).

European Heart Journal, 2021
BACKGROUND Patients with non-left-main coronary bifurcation lesions are usually best treated with a stepwise provisional approach. However, patients with true left main stem bifurcation lesions have been shown in one dedicated randomized study to benefit

Hopf bifurcation control of the ML neuron model with Hc bifurcation type

Electronic Research Archive, 2022
It is shown that many neurological diseases are caused by the changes of firing patterns induced by bifurcations. Therefore, the bifurcation control may provide a potential therapeutic method of these neurodegenerative diseases.

Relationship between modifiable atherosclerotic cardiovascular risk factors and coronary artery bifurcation lesion

Medical Journal of Babylon, 2023
Background: Modifiable atherosclerotic cardiovascular disease risk factors are hypertension, diabetes mellitus, dyslipidemia, cigarette smoking, and obesity; the term coronary artery bifurcation is used when a coronary artery divides into two ...
