Impact of surrounding tissue on conductance measurement of coronary and peripheral lumen area.
Parallel conductance (electric current flow through surrounding tissue) is an important determinant of accurate measurements of arterial lumen diameter, using the conductance method. The present study is focused on the role of non-uniform geometrical/electrical configurations of surrounding tissue, which are a primary source of electric current leakage. Computational models were constructed to ...
متن کاملCarotid artery stent placement with distal balloon protection: technical considerations.
BACKGROUND AND PURPOSE Most neurologic events that complicate the carotid artery stent placement procedure are embolic. Strategies are being developed and evaluated for their ability to minimize the clinical embolic risk. The purpose of this study was to determine the feasibility, safety, and technical considerations of performing carotid artery stent placement with use of a distal balloon anti...
متن کاملBalloon Sizing for Transcatheter Aortic Valve Replacement*
When the association of paravalvular leak (PVL) and increased mortality was first described in 2012 at the 2-year PARTNER I presentation (1), the transcatheter aortic valve replacement (TAVR) community reacted with great concern that this promising technology was beginning to show signs of weakness. Since then, a great deal of data has been reported from multiple registries confirming this asso...
متن کاملDrug-Coated Balloon Versus Standard Balloon for Superficial Femoral Artery In-Stent Restenosis: The Randomized Femoral Artery In-Stent Restenosis (FAIR) Trial.
BACKGROUND Drug-coated balloon angioplasty (DCBA) was shown to be superior to standard balloon angioplasty (POBA) in terms of restenosis prevention for de novo superficial femoral artery disease. For in-stent restenosis, the benefit of DCBA over POBA remains uncertain. METHODS AND RESULTS One hundred nineteen patients with superficial femoral artery in-stent restenosis and chronic limb ischem...
متن کاملEffect of Saline Injection Mixing on Accuracy of Conductance Lumen Sizing of Peripheral Vessels
Transient displacement of blood in vessel lumen with saline injection is necessary in the conductance method for measurement of arterial cross-sectional area (CSA). The displacement of blood is dictated by the interactions between arterial flow hemodynamics and saline injection dynamics. The objective of the present study is to understand how the accuracy of conductance measurements is affected...
