It was reported that the procedure was to treat a 100% stenosed, mildly tortuous, and de novo lesion in the mid right coronary artery.Following pre-dilatation with a 2.0x15mm non-abbott balloon a 2.75x28mm xience prime stent was deployed at the lesion site.Post-dilatation was performed with a 3.0x12mm nc non-abbott balloon and the procedure was successful without residual stenosis.Minutes after the procedure the patient had a myocardial rupture and myocardial infarction.Pericardial aspiration was performed; however, substantial amount of blood was aspirated from the pericardium and the patient condition worsened before any further treatment could have been given.The patient passed away.An autopsy was not performed.No additional information was provided.
