Based on the changes in the field of heart transplantation and the treatment and prognosis of patients with heart failure, these updated guidelines were composed by a committee under the supervision of both the Netherlands Society of Cardiology and the Netherlands Association for Cardiothoracic surgery (NVVC and NVT).THE INDICATION FOR HEART TRANSPLANTATION IS DEFINED AS: 'End-stage heart disease not remediable by more conservative measures'.CONTRAINDICATIONS ARE: irreversible pulmonary hypertension/elevated pulmonary vascular resistance; active systemic infection; active malignancy or history of malignancy with probability of recurrence; inability to comply with complex medical regimen; severe peripheral or cerebrovascular disease and irreversible dysfunction of another organ, including diseases that may limit prognosis after heart transplantation.Considering the difficulties in defining end-stage heart failure, estimating prognosis in the individual patient and the continuing evolution of available therapies, the present criteria are broadly defined. The final acceptance is done by the transplant team which has extensive knowledge of the treatment of patients with advanced heart failure on the one hand and thorough experience with heart transplantation and mechanical circulatory support on the other hand.

The functioning of non-heart-beating (NHB) donor kidneys upon transplantation is often delayed. To evaluate the effect of preservation by machine perfusion (MP) on early post-transplant function, 37 NHB donor kidneys were compared to 74 matched heart-beating (HB) donor kidneys preserved by cold storage (CS). The NHB donor kidneys were subject to 49 +/- 34 min of warm ischemia. Delayed function (DF) and primary nonfunction (PNF) rates were significantly higher for NHB than for HB donor kidneys (49% and 19% vs 34% and 7%, respectively). Consequently, renal function was impaired but recovered within 6 months. MP could not eliminate the differences in DF rate between NHB and HB donor kidneys. However, NHB donor kidneys preserved by MP showed less DF than that reported in kidneys preserved by CS. This suggests that MP has a beneficial effect on ischemically damaged kidneys. The similar results observed with category 2 and category 3 NHB donors also suggest this effect. The high PNF rate emphasizes the need for viability tests that prevent the transplantation of nonviable organs. We conclude that MP alone is not sufficient to reduce DF and PNF rates in NHB donor kidneys.

AbstractThe functioning of nonheart-beating (NHB) donor kidneys upon transplantation is often delayed. To evaluate the effect of preservation by machine perfusion (MP) on early post-transplant function, 37 NHB donor kidneys were compared to 74 matched heartbeating (HB) donor kidneys preserved by cold storage (CS). The NHB donor kidneys were subject to 49 f 34 min of warm ischemia. Delayed function (DF) and primary nonfunction (PNF) rates were significantly higher for NHB than for HB donor kidneys (49 YO and 19 Yo vs 34 Y and 7 YO, respectively). Consequently, renal function was impaired but recovered within 6 months. MP could not eliminate the differences in DF rate between NHB and HB donor kidneys. However. NHB donor kidneys preserved by MP showed less D F than that reported in kidneys preserved by CS. This suggests that MP has a beneficial effect on ischemically damaged kidneys. The similar results observed with category 2 and category 3 NHB donors also suggest this effect. The high PNF rate emphasizes the need for viability tests that prevent the transplantation of nonviable organs. We conclude that MP alone is not sufficient to reduce DF and PNF rates in NHB donor kidneys.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
