Antegrade wiring, antegrade dissection and reentry, and the retrograde approach are all complementary and necessary crossing strategies. Antegrade wiring is the most common initial technique, whereas retrograde and antegrade dissection and reentry are often required for more complex CTOs. 5.
27 de abr. de 2020 · The 10 steps of retrograde chronic total occlusion (CTO) percutaneous coronary intervention. CART indicates controlled antegrade and retrograde tracking; CC, collateral channel; and SVG, saphenous vein graft. Step 1: When to Go Retrograde?
In this technique, antegrade and retrograde microcatheters are aligned in a guide catheter at the level of the ascending aorta, after which an antegrade wire is pulled into a retrograde microcatheter. The antegrade wire is advanced further down beyond the CTO site through the retrograde microcatheter .
29 de jun. de 2020 · Registries consistently show that antegrade wiring (AW) is the most common strategy for crossing CTOs, particularly those of lower complexity. [ 1, 5] However, it is important to understand that to safely achieve a high success rate in CTO PCI, expertise in dissection and re-entry techniques (DART) and retrograde approaches are also required.
1 de jul. de 2021 · Retrograde approach increases the success rate of CTO PCI in complex subsets. 3 Comparing “Antegrade only” approach, retrograde approach has higher complication rates, 12 however, the long term outcome is equally good. 13 Retrograde CTO PCI can be attempted through septal and epicardial collaterals or bypass grafts.
15 de jun. de 2016 · Given the higher potential for complications with the retrograde strategies, an initial, more vigorous antegrade attempt may be appropriate in most CTO patients. In the PROGRESS CTO registry, the complication rate, which remains acceptably low especially if considering the complexity of population, might have been even lower with a ...
1 de dic. de 2018 · Angiographic features of blunt occlusion with a large side branch, bridging collaterals, calcification, and long CTO are no longer considered negative predictors of success while embarking on a retrograde approach. 15 The most common indication of this approach is unsuccessful antegrade approach.
