Computational modeling of in-stent restenosis: Pharmacokinetic and pharmacodynamic evaluation [PDF]

arXiv, 2023
Persistence of the pathology of in-stent restenosis even with the advent of drug-eluting stents warrants the development of highly resolved in silico models. These computational models assist in gaining insights into the transient biochemical and cellular mechanisms involved and thereby optimize the stent implantation parameters.

Drug‐Coated Balloons Versus Non‐Coated Balloons for Side Branch Treatment in Bifurcation Lesions: A Systematic Review and Meta‐Analysis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary bifurcation lesions (CBL) account for ~20% of percutaneous coronary interventions (PCI). When using provisional stenting, optimal management of a diseased side branch (SB) remains debated. Drug‐coated balloons (DCBs) are an emerging option, but data on their role in CBL PCI are limited.

Use of ReCross to Increase Success Rate With Antegrade CTO PCI—A Multicenter Observational Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Antegrade approach remains one of the predominant techniques for CTO PCI. Success rates have increased significantly recently due to advancements in devices and strategies, along with the hybrid algorithm. ReCross is a uniquely modified microcatheter with two over‐the‐wire lumens and three exit ports, offering significant potential ...

The First‐in‐Man Technique of Drug Eluting and Perfusion Therapy for Left Main Coronary Artery Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Treating ostial left circumflex artery (LCx) lesions in percutaneous coronary intervention (PCI) for left main disease (LMD) remains a challenge. Despite recent recommendations for the use of drug‐coated balloon (DCB) in this lesion, there are concerns about crossover‐stenting from the left main trunk (LMT) to the left anterior ...

Coronary Artery Vasculopathy in a Cohort of Heart Transplant Recipients: A Single Center Experience

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary allograft vasculopathy (CAV) is a significant cause of late mortality in heart transplant recipients. This study assesses the development of CAV, associated rejection rates, and the potential impact of percutaneous coronary intervention (PCI) on survival in a cohort of heart transplant patients.

Hemodynamics of Stent Implantation Procedures in Coronary Bifurcations: an in vitro study [PDF]

arXiv, 2016
Stent implantation in coronary bifurcations presents unique challenges and currently there is no universally accepted stent deployment approach. Despite clinical and computational studies, to date, the effect of each stent implantation method on the coronary artery hemodynamics is not well understood.

Revascularization of a Saphenous Vein Graft Ostial Stenosis in a Patient With Marfan Syndrome and a Previous Bentall Procedure Who was Resuscitated From Ventricular Fibrillation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT A 24‐year‐old male with Marfan syndrome was admitted following an episode of ventricular fibrillation (VF) during exercise. He had previously undergone multiple aortic surgical procedures for symptomatic aortic regurgitation and an ascending aortic false aneurysm.

Immediate Small Side Branch Occlusion after Percutaneous Coronary Intervention [PDF]

Journal of Tehran University Heart Center, 2007
Background: Small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. Nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch ...

Interfacing exogenous stents with human coronary artery by self-assembled coating: designs, functionalities and applications

NPG Asia Materials
Drug-eluting stents are a commonly used treatment for coronary artery disease. However, the coatings used in drug-eluting stents have some limitations such as poor biocompatibility and drug loading capacity.

Bioresorbable Scaffold Visualization in IVOCT Images Using CNNs and Weakly Supervised Localization [PDF]

arXiv, 2018
Bioresorbable scaffolds have become a popular choice for treatment of coronary heart disease, replacing traditional metal stents. Often, intravascular optical coherence tomography is used to assess potential malapposition after implantation and for follow-up examinations later on.
