Journal ArticleDOI
A Calcific, Undilatable Stenosis: Lithoplasty, a New Tool in the Box?
Kalpa De Silva,James Roy,Ian Webb,Rafal Dworakowski,Narbeh Melikian,Jonathan Byrne,Philip MacCarthy,Jonathan Hill +7 more
TL;DR: A 69-year-old man with established coronary artery disease and left ventricular dysfunction (ejection fraction, 40%) with typical Canadian Cardiovascular Society class III angina underwent percutaneous coronary intervention (PCI) for severe diffuse calcific disease in the right coronary artery as discussed by the authors.
Journal ArticleDOI

Brilakis,Antonio Colombo,Stéphane Rinfret,Kambis Mashayekhi +30 more
TL;DR: The objective was to evaluate the outcomes of subadventitial stenting around occluded stents for recanalizing in‐stent chronic total occlusions (IS‐CTOs) and to investigate the role of EMT in these events.
Journal ArticleDOI
Selective anti-scatter grid removal during coronary angiography and PCI: a simple and safe technique for radiation reduction
James Roy,Philip Sun,Glenn Ison,Ananth M. Prasan,Thomas J. Ford,Andrew P. Hopkins,Andrew P. Hopkins,David R. Ramsay,James C. Weaver,James C. Weaver +9 more
TL;DR: Removing the anti-scatter grid (ASG) is a simple and effective method to significantly reduce radiation dose in coronary angiography and PCI while maintaining adequate diagnostic image quality.
Journal ArticleDOI
The “side-BASE technique”: Combined side branch anchor balloon and balloon assisted sub-intimal entry to resolve ambiguous proximal cap chronic total occlusions
TL;DR: The evolution of the “BASE” technique is described and examples where the sub‐intimal space was accessed proximal to the occlusion by using the side branch are highlighted.
Journal Article
The Difference Between Success and Failure: Subintimal Stenting Around an Occluded Stent for Treatment of a Chronic Total Occlusion Due to In-Stent Restenosis.
TL;DR: A case where conventional wire and equipment passage through the proximal cap of a chronic total occlusion due to in-stent restenosis was not possible and the lesion was safely and successfully treated by deliberate passage into the subintimal space outside the previous stent.
