INTRODUCTION AND OBJECTIVES Provisional stenting has been shown to be effective in the treatment of bifurcated coronary lesions. The aim of this study was to evaluate changes in the geometry of the main vessel stent following side branch (SB) dilatation and kissing balloon (KB) inflation. METHODS The study involved 23 patients with a bifurcated coronary lesion. A first intravascular ultrasoun...
AIMS This study was performed to evaluate the functional outcomes of fractional flow reserve (FFR)-guided jailed side-branch (SB) intervention strategy. METHODS AND RESULTS One hundred and ten patients treated by provisional strategy were consecutively enrolled and SB FFR was measured in 91 patients. SB intervention was allowed when FFR was <0.75. FFR measurement was repeated after SB interve...
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...
