Transient cerebral ischemic attacks associated with worn porcine heterograft prosthesis. Case report
F Stahmann, HW Knott and DB Doty
Details are reviewed of a case of transient cerebral ischemic attacks which
probably resulted from thromboembolism from a Hancock porcine heterograft
prosthesis. Cause of the embolism probably was thrombus formation on the
worn cloth covering of the supporting valve stent. Technical and antomic
factors which assure precise seating of the prosthesis in the mitral anulus
without contacting the ventricular wall appear to be important in
preventing this complication.
