Resistance was subjectively evaluated and recorded as absent (double circle), slight (single circle), and strong (triangle). The impossibility of passing 2 microdevices inside the guiding catheter was also recorded (×). -: not performed. To measure maximal resistance (in Newtons) we used a digital push-pull gauge (lower section)
