Bailout technique to rescue the abruptly occluded side branch with collapsed true lumen after main vessel stenting
Guidewire recrossing into the abruptly occluded side branch (SB) after main vessel (MV) stenting in the coronary bifurcation is difficult, particularly if the SB has a dissection because the true lumen of SB is collapsed by a hematoma and the second guidewire easily goes into the false lumen. This paper reports a bailout technique to rescue the occluded SB that was complicated by a hematoma bec...
متن کاملInitial Experience and Feasibility of the New Low-Profile Stingray Catheter as Part of the Antegrade Dissection and Re-Entry Revascularization Strategy for Coronary Chronic Total Occlusions
BACKGROUND During antegrade dissection re-entry (ADR) of chronic total occlusions (CTO), the first-generation Stingray catheter requires the use of large-bore guides (sheathless 7.5 Fr or 8 Fr), which increases the risk for access site-related complications and compromises radial approaches. Smaller guiding sizes necessitate long guidewires (e.g., 300 cm) or guidewire extensions for catheter ad...
متن کاملCoronary artery dissection caused by exit of the guidewire through the distal perfusion sidehole of an auto-perfusion angioplasty balloon catheter.
A previously unrecognized cause of coronary artery dissection is reported. A 67-year-old woman underwent angioplasty of the right coronary artery using an autoperfusion balloon catheter. Dissection occurred because the balloon catheter was advanced while the guidewire exited from one of the distal perfusion sideholes.
متن کاملAdvances in Procedural Techniques - Antegrade
There have been many technological advances in antegrade CTO PCI, but perhaps most importantly has been the evolution of the "hybrid' approach where ideally there exists a seamless interplay of antegrade wiring, antegrade dissection re-entry and retrograde approaches as dictated by procedural factors. Antegrade wire escalation with intimal tracking remains the preferred initial strategy in shor...
متن کاملA simple practical balloon anchoring technique within the guide catheter for chronic total occlusion (CTO) of the coronary artery
Dear Editor: Chronic total occlusions (CTOs) of the coronary artery are commonly encountered complex lesions [1] . Percutaneous coronary intervention (PCI) for CTO is technically challenging due to low procedural success rates [2] . Microcatheter is one of the important devices for treatment of CTO [3] . It has been widely used attributed to the excellent crossability whenever angulation and to...
