Our current study evaluates the flow velocity patterns of the graft before and after PTCA. After intervention the mean diastolic flow velocity increased under rest and stress conditions. In addition, the graft patency was proved not before control angiography after 6 months. It could be verified that the measurement of flow velocity patterns under rest and stress conditions is a useful non-invasive procedure for monitoring long-term patency and PTCA-results of this vessel.
