          Abstract

          A pesar de las mejoras significativas en los criterios de selección de los receptores de trasplante cardíaco, la mejor preservación de los órganos, las nuevas terapéuticas inmunosupresoras y los avances en el cuidado postrasplante, los pacientes que recibieron un trasplante cardíaco continúan con una tasa alta de falla temprana y tardía del injerto. Se han propuesto múltiples intervenciones terapéuticas para estos casos; sin embargo, los dispositivos de asistencia ventricular y el retrasplante cardíaco permanecen como el tratamiento definitivo para este subgrupo de pacientes. En esta presentación se describe un caso de shock cardiogénico refractario posinfarto agudo de miocardio en un paciente con trasplante cardíaco previo, que fue tratado en forma consecutiva con balón de contrapulsación intraaórtico, cirugía de revascularización miocárdica y, finalmente, por continuar en shock cardiogénico refractario con falla multiorgánica, recibió asistencia circulatoria con Levitronix® CentriMag® como puente al retrasplante. Luego de 21 días en asistencia ventricular y mejoría franca de la falla multiorgánica, se realizó el trasplante ortotópico.

          Despite the significant advances in recipient selection criteria for cardiac transplantation, organ preservation techniques, novel immunosuppressive agents, and care following transplantation, early and late graft failures are still high in heart transplant recipients. Several therapeutic interventions have been described for these cases; however, the use of ventricular assist devices and cardiac retransplantation still remain as the definite treatment for this subgroup of patients. We describe a case of refractory cardiogenic shock due to acute myocardial infarction in a patient with a history of heart transplantation that was consecutively treated with intraaortic balloon pump and myocardial revascularization surgery. Despite therapy, the patient remained in refractory cardiogenic shock with múltiple organ failure and received Levitronix® CentriMag® as a bridge to retransplantation. After 21 days under circulatory support, múltiple organ failure reverted and the patient underwent orthotopic heart transplantation.

            Clinical performance with the Levitronix Centrimag short-term ventricular assist device.

            The Levitronix ventricular assist device (VAD) is a centrifugal pump designed for extracorporeal support and that operates without mechanical bearings or seals. The rotor is magnetically levitated so that rotation is achieved without friction or wear, which seems to minimize blood trauma and mechanical failure. The aim of this study is to report our early results with the Levitronix Centrimag device. Between June 2003 and April 2005, 18 patients (pts) were supported using the Levitronix at our institution. Fourteen were male. Mean age was 40.3 +/- 18.3 (range 8 to 64) years. Indications for support at implantation were: post-cardiotomy cardiogenic shock in 12 cases (Group A), and bridge to decision regarding long-term ventricular support in 6 cases (Group B). Mean support time was 14.2 +/- 15.2 days for all patients (range 1 to 64 days). Operative (30-day) mortality was 50% (9 pts). Six pts were in Group A and 3 pts were in Group B. Overall, 6 pts (33%) were discharged home and are presently alive and well (mean follow-up 13 months, range 5 to 17 months). Bleeding requiring re-operation occurred in 8 cases (44%), cerebral thromboembolism in 1 and pulmonary embolism in 1. There were no device failures. The Levitronix functioned well and proved to be useful in patients with extremely poor prognosis previously considered non-suitable for a long-term assist device. The device was technically easy to implant and manage. There was no device dysfunction and complications were acceptable or consistent with other devices. Survival to explant or a definitive procedure (VAD or transplantation) was encouraging.

              Left ventricular assist device implantation after acute anterior wall myocardial infarction and cardiogenic shock: a two-center study.

              Left ventricular assist device (LVAD) insertion after anterior wall myocardial infarction complicated by cardiogenic shock is an accepted modality of support in select patients. Results of primary revascularization for these patients are poor. We seek to determine the outcomes of patients with myocardial infarction and shock who undergo LVAD insertion alone versus surgical revascularization before LVAD insertion.
