The use of an implantable left ventricular assist device in a patient with cardiogenic shock following acute myocardial infarction

We report the successful long-term use of an implantable left ventricular assist device in a 42-year old patient who suffered cardiogenic shock after an acute anterior myocardial infarction unresponsive to recanalisation of the infarct-related artery and intra-aortic balloon counterpulsation. Attempts to wean our patient from the assist device were not successful and the patient underwent cardiac transplantation after 35 weeks on device assistance. The intermediate and long-term use of an implantable left ventricular assist device may be lifesaving in post-myocardial infarction cardiogenic shock and may allow sufficient time for any stunned myocardium to recover. Should there be no recovery, the device acts as a bridge to cardiac transplantation.
