Antegrade approach to stumpless chronic total occlusion of ostial left anterior descending artery: first using a side branch cutting technique.
The approach to a chronic total occlusion (CTO) still remains one of the most technical challenges in percutaneous coronary intervention (PCI). CTO lesions with a blunt entry point, calcification, and failure of a previous approach, are the independent predictors of CTO-PCI failure. Here we report a successful antegrade approach for reattempted CTO-PCI of a left anterior descending artery (LAD)...
متن کاملCTO Pathophysiology: How Does this Affect Management?
UNLABELLED Chronic total occlusion (CTO) pathophysiology has been described in a few, small studies using post mortem histology, and more recently, in vivo intravascular ultrasound (IVUS) to analyse the constituents of occluded segments. Recent improvements in equipment and techniques have revealed new insights into physical characteristics of occluded coronaries, which in turn enable predictab...
متن کاملRotational Atherectomy of a Lesion in Which Stent Expansion Was Limited by Severe Calcification
receiving at the time of admission, consisting of atenolol, atorvastatin and aspirin, clopidogrel, and intravenous infusion of nitroglycerin was initiated and cardiac catheterization was performed. The left ventricle, which was hypertrophic and presented moderate hypokinesia of the apical region, preserved an ejection fraction of 63%. The bifurcation of the left main cononary artery presented a...

متن کاملShear Laver Coupling with Side-branch Resonators
High velocity flow past the junction of a side branch with a pipe can result in the excitation of depth-mode standing waves in the branch. The shear layer separating the main stream flow and the cavity provides coupling between the driving and the driven fl ow. Photographi c evi dence i ndi cates that 1arge scale vortex structures develop at the shear layer. The vortex formation process involve...
