Abstract/OtherAbstract:
BACKGROUND: The feasibility of left ventricular restoration for patients with ischemic cardiomyopathy complicated with cardiogenic shock remains unclear. We report early and mid-term outcomes of surgical interventions including left ventricular restoration for patients with cardiogenic shock. METHODS: From April 2001 to June 2007, 10 patients with ischemic cardiomyopathy who developed cardiogenic shock underwent left ventricular restoration combined with mitral annuloplasty or coronary artery bypass grafting. All had been supported by a maximum dose of inotropic agents, 8 had required an intraaortic balloon pump, and 1 had required extracorporeal life support. Mean left ventricular end-diastolic and end-systolic volume indices were 142 +/- 33 mL/m(2) and 113 +/- 28 mL/m(2), respectively, and ejection fraction was 0.21 +/- 0.059. RESULTS: There was no mortality at 30 days. Five patients demonstrated significant recovery after the operation. Three patients simultaneously underwent left ventricular assist system (LVAS) implantation with left ventricular restoration because of preexisting severe end-organ failure, and 2 of them were subsequently weaned from LVAS, although 1 required reimplantation. The other 2 patients eventually underwent LVAS implantation in the early postoperative period. Two patients who required prolonged LVAS support underwent successful heart transplantation. Seven patients are alive at a mean follow-up of 1.9 years. Patients who required prolonged LVAS support had significantly longer duration of heart failure symptoms (p = 0.04) and higher mean pulmonary artery pressure (p = 0.02) preoperatively. CONCLUSIONS: Early combined surgical interventions including left ventricular restoration can be a choice of treatment even in patients with ischemic cardiomyopathy complicated with cardiogenic shock. Additional use of the LVAS followed by bridge to recovery or transplantation should be appropriately applied in these critically ill patients.
