It was reported that the procedure was to treat a heavily calcified, moderately tortuous de novo left anterior descending artery (lad), left circumflex (lcx) and the left main (lm).Five xience sierra stents were implanted (2.25x23 mm, 2.75x28 mm, 3.0x38 mm, 2.75x28 mm and 3.0x18 mm).Complications were noted during final dilatation in the left main artery.The patient went into bradycardia and cardiogenic shock and was intubated and transferred to the intensive care unit.It is assumed that a dissection from the lcx caused the complications.The patient expired and a clinically significant delay was reported.No additional information was provided.
