Emergency cardiopulmonary support has been used in the United States s
ince 1986, mainly by physicians at participating centers for the Natio
nal Registry of Elective Supported Angioplasty. Data from the National
Registry as well as the experience in three institutions from a numbe
r of operators were analyzed to assess the benefits of the emergency c
ardiopulmonary support application in patients with hemodynamic collap
se. Patients who had experienced either cardiac arrest or hemodynamic
collapse with cardiogenic shock unresponsive to pressors were placed e
mergently on cardiopulmonary support. They were either then treated wi
th angioplasty or with revascularization surgery. Patients placed on c
ardiopulmonary support in less than 15 min experienced a 48% survival
rate across the whole registry of the participating centers of the Nat
ional Cardiopulmonary Bypass Registry. A two-center experience has dem
onstrated a 69% survival rate. Patients treated with emergency cardiop
ulmonary support who have experienced hemodynamic collapse have improv
ed survivorship over any other hemodynamic support system. With increa
sing experience by the operators, the results have improved for surviv
orship, particularly in the early application group.
