RESUMO
Ventricular assist devices have been shown to be effective in advanced heart failure selected patients. They often have borderline end-organ function, what facilitates organ dysfunction. Liver failure is difficult to manage and leads to increased morbidity and mortality. We report a case of ductular cholestasis, an unusual cholestatic hepatic failure with untractable coagulopathy, developed during the use of a magnetic levitation centrifugal pump, implanted as a bridge to heart transplantation, in a patient with cardiogenic shock (as an end-stage disease of idiopathic dilated cardiomyopathy). We discussed the pathophysiology of this entity and the possible related factors, including the assist device. Preemptive interventions have been advocated as the primary way of treatment. Preoperative optimization of heart function and avoidance of visceral hypoperfusion and sepsis may play a major role.

The development of postoperative ventricular dysfunction immediately after heart transplantation is a serious complication that leads to low-output syndrome and which necessitates circulatory support. It is one of the most common causes of early morbidity and mortality. We present our experience with 6 heart transplant patients who were treated with intravenous levosimendan, a calcium sensitizer with inodilator properties, after regular hemodynamic therapy with sympathomimetic amines failed to result in a satisfactory hemodynamic status. Use of this drug was well tolerated and brought about hemodynamic improvements that were sufficient to enable patients to be weaned from inotropic support with amines and which led to clinical recovery, with 5 of the 6 patients being discharged from the intensive care unit.

La disfunción ventricular del injerto en el postoperatorio inmediato del paciente trasplantado cardiaco es una complicación grave, que cursa con un síndrome de bajo gasto cardiaco y necesidad de soporte circulatorio, y es una de las causas más frecuentes de morbimortalidad inicial. Presentamos la experiencia clínica con 6 pacientes trasplantados en los que, tras un manejo hemodinámico habitual con aminas simpaticomiméticas, no se consiguió una adecuada situación hemodinámica y se utilizó levosimendán intravenoso, un fármaco sensibilizador al calcio con propiedades inodilatadoras. El uso de este fármaco fue bien tolerado y favoreció una mejoría hemodinámica que facilitó la retirada del soporte inotrópico con aminas y la recuperación clínica (con alta de UCI de 5 de los 6 pacientes) (AU)
