Visualization of the Thebesian veins during coronary angiography in a 57-year-old woman

Scoglio, Martin ; Cook, Stéphane

In: Oxford Medical Case Reports, 2020, vol. 2020, no. 7, p. omaa053

A 57-year-old woman was hospitalized due to a type 2 respiratory failure. Electrocardiogram at admission showed inverted T waves in leads V2–V4. Coronary angiogram was performed showing no relevant stenosis. However, this exam allowed visualization of the Thebesian veins outlining the left ventricle.

Absorb bioresorbable scaffold versus xience metallic stent for prevention of restenosis following percutaneous coronary intervention in patients at high risk of restenosis: rationale and design of the COMPARE ABSORB trial

Chang, Chun Chin ; Onuma, Yoshinobu ; Achenbach, Stephan ; Barbato, Emanuele ; Chevalier, Bernard ; Cook, Stéphane ; Dudek, Dariusz ; Escaned, Javier ; Gori, Tommaso ; Kočka, Viktor ; Tarantini, Giuseppe ; E.J.West, Nick ; Morice, Marie-Claude ; G.P.Tijssen, Jan ; Geuns, Robert-Janvan ; C.Smits, Pieter

Background: The advent of bioresorbable vascular scaffolds (BVS) was considered as a potential improvement in percutaneous coronary intervention (PCI) after the groundbreaking development of drug eluting stents (DES). However, the clinical performance, long-term safety and efficacy of BVS in complex coronary lesions remain uncertain. COMPARE ABSORB, a multicenter, single blind, prospective ...

Diffusing wave microrheology of highly scattering concentrated monodisperse emulsions

Kim, Ha Seong ; Şenbil, Nesrin ; Zhang, Chi ; Scheffold, Frank ; Mason, Thomas G.

In: Proceedings of the National Academy of Sciences, 2019, vol. 116, no. 16, p. 7766–7771

Motivated by improvements in diffusing wave spectroscopy (DWS) for nonergodic, highly optically scattering soft matter and by cursory treatment of collective scattering effects in prior DWS microrheology experiments, we investigate the low-frequency plateau elastic shear moduli G′p of concentrated, monodisperse, disordered oil-in- water emulsions as droplets jam. In such experiments, the...

Brownian dynamics of colloidal microspheres with tunable elastic properties from soft to hard

Yoon, Jiwon ; Cardinaux, Frédéric ; Lapointe, Clayton ; Zhang, Chi ; Mason, Thomas G. ; Ahn, Kyung Hyun ; Scheffold, Frank

In: Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2018, vol. 546, p. 360–365

We study the Brownian thermal motion of a colloidal model system made by emulsifying hot liquid α-eicosene wax into an aqueous surfactant solution of sodium dodecyl sulfate (SDS). When this waxy oil-in-water emulsion is cooled below α- eicosene's melting point of Tc ≃ 25 °C, the microscale emulsion droplets solidify, effectively yielding a dispersed particulate system. So, the...
