Predictors and Prognostic Implications of Well-Matured Coronary Collateral Circulation in Patients with a Chronic Total Occlusion (CTO).

International Heart Journal, 2020
The predictors and prognostic implications of well-matured collaterals in those with a chronic total occlusion (CTO) are unknown. We sought to identify the determinants of collateral maturation and to determine its effects on procedural outcomes and ...

Management of coronary chronic total occlusion

Cleveland Clinic Journal of Medicine, 2017
Percutaneous coronary intervention (PCI) for coronary artery chronic total occlusion (CTO) is an important treatment to be used in conjunction with non-CTO PCI, coronary artery bypass grafting, and optimal medical therapy to achieve complete revascularization in patients with coronary artery disease.

Intrinsically Soft Printed Electronics for Digitally Augmented Human Sensing and Vision

Advanced Functional Materials, EarlyView.
This work introduces a class of highly functional, multilayer flexible and stretchable circuits capable of digitally augmenting human sensing and vision. Studies in multi‐material soft composite inks yielded a formulation that enables overpass printing, self‐healing, and high‐resolution functionality.

Factors Influencing Stent Failure in Chronic Total Occlusion Coronary Intervention

Interventional Cardiology: Reviews, Research, Resources, 2021
Stent failure remains one of the greatest challenges for interventional cardiologists. Despite the evolution to superior second- and third-generation drug-eluting stent designs, increasing use of intracoronary imaging and the adoption of more potent ...

Chronic total occlusion: To treat or not to treat

World Journal of Cardiology, 2014
Over the last two decades, there has been increasing interest in new techniques for the percutaneous treatment of coronary chronic total occlusions (CTO), which have a success rate that is much higher than that of a few years ago. The rise in percutaneous treatment for these lesions is due to its ability to improve the symptoms and prognosis of ...

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Efficacy and safety of recanalization with transseptal needle for chronic total occlusion of the brachiocephalic vein in hemodialysis patients

Annals of Translational Medicine, 2020
Background Whilst there are effective techniques for the recanalization of central venous occlusions, recanalization of chronic total occlusions remains particularly challenging. This study aims to evaluate the safety and efficacy of recanalization using

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin

Advanced Healthcare Materials, EarlyView.
Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.

Predictors of unsuccessful endovascular recanalization of coronary chronic total occlusion

Кардиоваскулярная терапия и профилактика, 2021
The prevalence of endovascular interventions for coronary chronic total occlusion (CTO) remains small worldwide. This is due to the complexity of procedure and the risk of intraoperative complications.

A case of pancreatic cancer with concomitant median arcuate ligament syndrome treated successfully using an allograft arterial transposition [PDF]

, 2015
An association of pancreatic cancer and median arcuate ligament syndrome (MALS) is a rare and challenging situation in terms of treatment. A 60-year-old man diagnosed with pancreatic cancer underwent laparotomy. A pancreaticoduodenectomy was planned, but
