Could fractional flow reserve guide therapeutic strategy in acute coronary syndrome?
Fractional flow reserve, as determined with a pressure-wire, was validated in the assessment of the functional severity of intermediate lesions in a population with stable ischemic cardiopathy. The value of pressure-wire analysis in acute coronary syndrome is unknown. We report two patients with acute coronary syndrome, in which the therapeutic approach was guided by the fractional flow reserve. We discuss the utility of this tool in this context.
