Role of Intravascular Imaging in Percutaneous Coronary Interventions for Left Main Coronary Bifurcation Lesions

Инновационная медицина Кубани
The number of interventions for left main coronary bifurcation lesions in the Russian Federation increase annually. Such lesions are among the most challenging cases for endovascular treatment due to a high risk of cardiovascular complications.

Cholinergic neural activity directs retinal layer-specific angiogenesis and blood retinal barrier formation. [PDF]

, 2019
Blood vessels in the central nervous system (CNS) develop unique features, but the contribution of CNS neurons to regulating those features is not fully understood. We report that inhibiting spontaneous cholinergic activity or reducing starburst amacrine

Guidewire Manipulation Based on Establishment of Stereo Perception in Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Traditional percutaneous coronary intervention (PCI) relies on two‐dimensional X‐ray imaging, but this does not allow depth perception and complicates precise manipulation of the guidewire. Our purpose was to develop a novel method for guidewire manipulation by establishing stereoscopic perception in coronary angiography (CAG), as ...

OCT‐Guided Distal Left Main Bifurcation PCI: Mid‐Term Outcomes From a Multicenter South‐Asian Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Optical coherence tomography (OCT)‐guided percutaneous coronary intervention (PCI) enhances treatment of complex coronary artery lesions, including left main (LM) disease, by enabling lesion morphology assessment and stent optimization, thereby reducing major adverse cardiac events (MACE).

Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
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 ...

A Prospective, Multicenter, Open Label Study Investigating the Implementation of a Standardized Algorithm for Coronary CaLcificatiOn With PlaquE Modification Using UltraSound Guidance to Improve Procedural and Clinical Outcomes (CYCLOPES): Design and Rationale of the CYCLOPES Trial

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Introduction Moderate‐to‐severe calcification is present in ~20%–30% of patients undergoing coronary angiography. Coronary lesion modification is often necessary to facilitate optimal stent delivery and expansion, with several dedicated devices now approved for calcium modification before stent implantation. The CYCLOPES study aims to evaluate

Treatment of Coronary Perforation in a Bifurcation: Two‐Stent Strategies With Fenestrated Covered Stents

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

ESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).
