摘      要：Background:Fractional flow reserve (FFR) has become an increasingly important index when making decisions with respect to revascularization of coronary artery ***,the pressure guidewire used in obtaining FFR measurements is difficult to control and manipulate in certain complex coronary artery lesions,resulting in increased fluoroscopy time and contrast dye *** study examined a novel (NOV) technique for obtaining FFR measurements in hope of easing the difficulties associated with evaluating and treating complex coronary artery ***:Fifty-six patients with complex coronary artery lesions were assigned to a conventional (CON) FFR technique group or a NOV FFR technique *** NOV technique involved the use of a balloon and wire exchange within the coronary *** fluoroscopy time,contrast dye usage,and FFR-related complications were assessed after completing the FFR measurement procedure for each ***:The median time required for fluoroscopy in the NOV technique group was significantly less than that in the CON technique group; additionally,lesser amounts of contrast dye were used in the NOV technique group (both P 0.05).The NOV technique was successfully performed in thirty patients,without any FFR-related ***,the CON technique failed in three patients,including two who experienced coronary artery spasms (P 0.05).Conclusions:Compared to the CON technique used for measuring FFR,the new technique reduced the fluoroscopy time and amount of contrast dye used when evaluating complex coronary artery *** new technique did not increase the risk of operation or decrease the success rate.
