Flow Patterns at Stented Coronary Bifurcations
Coronary bifurcations remain one of the most challenging lesion subsets, even in the era of drug-eluting stents. Single stent implantation in the main vessel with provisional stenting to the side branch vessel has been found superior to double stenting and is considered the default approach in most coronary bifurcation lesions. However, in true bifurcation lesions, this provisional approach may...
متن کاملFlow patterns at stented coronary bifurcations: computational fluid dynamics analysis.
BACKGROUND The ideal bifurcation stenting technique is not established, and data on the hemodynamic characteristics at stented bifurcations are limited. METHODS AND RESULTS We used computational fluid dynamics analysis to assess hemodynamic parameters known affect the risk of restenosis and thrombosis at coronary bifurcations after the use of various single- and double-stenting techniques. We...
متن کاملLuminal Flow Amplifies Stent-Based Drug Deposition in Arterial Bifurcations
BACKGROUND Treatment of arterial bifurcation lesions using drug-eluting stents (DES) is now common clinical practice and yet the mechanisms governing drug distribution in these complex morphologies are incompletely understood. It is still not evident how to efficiently determine the efficacy of local drug delivery and quantify zones of excessive drug that are harbingers of vascular toxicity and...
متن کاملNonsymmetrical Bifurcations in Arterial Branching
I N T R O D U C T I O N It has long been suspected that the branching angles of blood arteries in the cardiovascular system are based on well-defined physiological principles. The cardiovascular system being basically a fluid-conducting system, these physiological principles are generally sought in the context of fluid dynamics. Several principles have so far been examined (Murray, 1926 b; Kami...
متن کاملNonsymmetrical bifurcations in arterial branching
The results of optimality studies of the branching angles of arterial bifurcations are extended to nonsymmetrical bifurcations. Predicted nonsymmetrical bifurcations are found to be not unlike those observed in the cardiovascular system.
