It was reported that the procedure was to treat a moderately calcified, 90% stenosed, 30mm-long lesion in the moderately tortuous proximal left anterior descending (lad) coronary artery.After crossing the lesion with a 014 hi-torque (ht) versaturn f 190 hc guide wire, a 2.5mm non-abbott balloon dilatation catheter was advanced over the versaturn and pre-dilatation was performed.A 3.5x33mm rx xience xpedition stent delivery system (sds) was then advanced over the versaturn, but, prior to exiting the guiding catheter, resistance was met between the xience xpedition and the versaturn.When attempting to retract the xpedition over the versaturn, resistance was also felt between these two devices.Thus, both devices were removed as a single unit.A non-abbott guide wire was advanced, followed by advancement and deployment of a 3.5x33mm non-abbott stent.There were no adverse patient effects and no occurrence of a clinically significant delay.No additional information was provided.
