title: Emergency cardiopulmonary bypass support in patients with severe cardiogenic shock after acute myocardial infarction.
abstract: A total of 16 patients who developed severe cardiogenic shock were resuscitated with a percutaneous cardiopulmonary support system (PCPS). The etiology of shock was acute myocardial infarction (n = 7), or post-infarction left-ventricular (LV) free wall rupture (n = 9). After successful resuscitation with the PCPS, 15 patients underwent therapeutic interventions: closure of an LV rupture (n = 9), coronary artery bypass grafting (n = 4), percutaneous transluminal angioplasty (n = 1), and percutaneous transluminal coronary recanalization (n = 1). Of the 16 patients, 14 were weaned from PCPS or standard cardiopulmonary bypass. Six patients survived longer than 30 days, 3 (19 percent) of whom were discharged from the hospital. The long-term survival rate in the 6 patients who underwent coronary revascularization was 33 percent (2/6). Of the 9 patients with LV free wall rupture, 1 was discharged from the hospital. Even though it cannot be concluded, from this small number of patients, that cardiopulmonary resuscitation using PCPS improves survival, it appears that PCPS is a powerful resuscitative modality for seriously ill patients with acute myocardial infarction or LV rupture.
