OBJECTIVES The purpose of this study was to develop an adenosine-independent, pressure-derived index of coronary stenosis severity. BACKGROUND Assessment of stenosis severity with fractional flow(More)
BACKGROUND We studied the hemodynamic response to intravenous adenosine on calculation of fractional flow reserve (FFR). Intravenous adenosine is widely used to achieve conditions of stable hyperemia(More)
BACKGROUND Intravenous adenosine infusion produces coronary and systemic vasodilatation, generally leading to systemic hypotension. However, adenosine-induced hypotension during stable hyperemia is(More)
