Abstract:
Objective:To analyze the safety and effectiveness of application of modified double-lumen microcatheter in the measurement of fractional flow reserve(FFR) in coronary bifurcation lesions.Methods:Total of 28 patients with coronary bifurcation lesions in two centers were divided into two groups:conventional technique group(CON) and novel technique group(NOV). The fluoroscopy time, contrast dye usage and FFR-related complications of the two groups were analyzed retrospectively.Results:There were 16 cases in CON group and 12 cases in NOV group. The median time required fluoroscopy in NOV group was significantly less than that in CON group; additionally, lesser amounts of contrast dye were used in NOV group (both P<0.05). The NOV group procedures were successfully accomplished in all cases without complications, such as damage of the pressure sensor, SB spasm or dissection. However, The CON group failed in three patients, including two who experienced coronary artery spasms( P>0.05). Conclusions:Limited experience suggests that the application of modified double-lumen microcatheter in the jailed SB FFR measurement after MV stenting is a safe and technically feasible approach.
