A method of treating vessel occlusions including chronic total occlusions (CTO) of the coronary arteries, and to generally remove tissue material, is presented that relies on remotely actuated navigation of an interventional RF-capable ablation device to the occlusion and controlled application of ablative RF energy. The 190 cm retrograde wire is gently advanced along the ascending aorta and the common trunk to reach the venue of the catch-it maneuver, where it can enter the distal tip of the antegrade guide. The combined use of remote navigation-based precision Unique to retrograde CTO PCI is the risk for donor collateral-vessel perforation. Invasive Cardiol. Manual of Coronary Chronic Total Occlusion Interventions: A Step-by-Step Approach, Second Edition, is an easy to read reference for coronary chronic total occlusion interventions (CTO). The proper next step is to exchange the retrograde wire to a stiffer higher penetration force wire to puncture towards the antegrade space, better with real-time IVUS guidance. Presenter: Colm Hanratty. published first in 2007 retrograde CTO recanalization in 21 patients via septal collaterals, and since then still this route is the most frequently used approach for retrograde CTO PCI 5. Retrograde approach through the collateral channel has been recently proposed and has the potential to improve the success rate of percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) lession of the coronary arteries. Coronary angiogram revealed 2 V CAD (CTO of RCA and subtotal occlusion of LCx-LPL branch). Surmely et al. The technique of retrograde CTO PCI was first described in 1990 by Kahn and Hartzler, who used a saphenous vein graft (SVG) to perform PCI of occluded left anterior descending artery (LAD).13 Silvestri et al14 demonstrated retrograde stenting of the left main artery in 1996 using SVG. Describe RWE and RDR (R-CART and CART). Two comprehensive, step-by-step descriptions of the procedures were published this year (Catheter Cardiovasc Interv. The first and most important step of CTO PCI is to perform dual coronary injection, in nearly all cases. Epicardial collaterals. The proper next step is to exchange the retrograde wire to a stiffer higher penetration force wire to puncture towards the antegrade space, better with real-time IVUS guidance. To do this, you need to push the retrograde MC across the CTO body into the proximal true lumen of the CTO vessel. The Fundamentals of Retrograde CTO Technique.
