Ventricular assist devices have benefited patients with end-stage heart failure as a bridge to heart transplantation (HTx). We present our experiment of HTx using extracorporeal membrane oxygenation (ECMO) with Thoratec pneumatic ventricular assist device (TpVAD). ⋯ We used ECMO as a rescue procedure for acute hemodynamic deterioration. However, during ECMO support, left ventricular afterload increased. If prolonged support is required, TpVAD might be required: 15 (65%) of patients supported by ECMO with TpVAD needed to a wait a suitable donor. We recommend the application of ECMO for short-term support (within 1 week), and TpVAD as a bridge for medium- or long-term support.

To report clinical outcomes of kidney transplantation from cardiac death donors (DCD) in China, and to investigate its feasibility to expand the organ donor pool. ⋯ Although kidney transplantations from DCD donors showed a higher rate of DGF with a longer duration of graft recovery, we achieved favorable short-term clinical outcome in terms of graft survival and function. Donation after cardiac death can expand the organ donor pool in China.

Heart transplantation is the ultimate treatment for end-stage heart failure. Cardiac sarcoidosis has rarely been reported in heart transplantation worldwide. Their long-term prognosis after heart transplantation is unknown. Herein we have presented clinical and pathological observations among heart transplantation patients with isolated cardiac sarcoidosis. ⋯ Heart transplantation is a useful treatment for isolated cardiac sarcoidosis patients suffering end-stage heart failure. Often the diagnosis is difficult to establish before heart transplantation despite endomyocardial biopsy. No recurrence of sarcoidosis was observed among the allografted hearts.

Because of the strict Organ Transplantation Act, only 81 brain dead (BD) organ donations had been performed in Japan for 13 years since 1997. The Act was revised on July 17, 2010, allowing, organs to be donated after BD with consent from the family, if the subject had not denied organ donation previously. This act has lead to an expectation of a 6-7-fold increase in BD donation. ⋯ Topics of the education program were the revised transplant act and guidelines, family approach to organ donation, BD diagnosis, donor evaluation and management, organ procurement and preservation, allocation system, hospital development and family care. In the future, each OPC will be divided into special categories, such as the donor family OPC, the donor management OPC, and the operating room OPC. Therefore, we need to construct separate special education programs for each category.

Reactive oxygen species generated during liver reperfusion have been implicated in remote lung injury. In this study, we evaluate the protective effects of melatonin pretreatment against the increased pulmonary microvascular permeability. ⋯ Melatonin pretreatment prior to liver I/R can effectively reduce the pulmonary microvascular permeability and attenuate lipid peroxidation in the lungs.
