Background: The current gold standard for donor heart preservation is a three-bag-technique and storage in a cooler filled with slush ice. This technique can cause freezing injury with protein denaturation. We report our early experience with a single-use disposable device (SherpaPak™, Paragonix Technologies, MA, USA) specifically designed for sterile permanent temperature-controlled transportation of donor hearts. Methods: In this case control study with 2:1 matching we identified 21 patients after heart transplantation depending on type of organ transport (standard three-bag-technique vs. SherpaPak™). The outcome after donor heart storage in the SherpaPak™ was compared with donor heart transportation with the standard technique. Results: Since July 2018 seven patients (5 males; mean age 50.3±13.2years) underwent heart transplantation with the SherpaPak™ system. Cold ischemic time was longer in the SherpaPak™ group (207.7±23.3 vs. 181.6±21.9, P=0.027). SherpaPak™ kept the organ temperature at 5.1±0.8 ℃, with an average outside temperature of 21.4±3.6 ℃.Among all 21 transplanted patients four developed fatal early graft failure (28.6% vs. 21.4%, P=0.432). Over the first hours we noticed no difference in hemodynamic parameters, CK-MB levels or vasoactive-inotropic score. During first follow-up we noticed slightly better right heart function in the SherpaPak™ group (TAPSE 17.83±2.71 vs. 14.52±2.61 mm, P=0.020). We identified no positive blood cultures in the SherpaPak™ group within the first 30 days after heart transplantation. Conclusions:The SherpaPak™ provides a constant temperature during transportation with permanent monitoring, never dropping below 4 ℃.Organs transported with this novel device showed a normal perioperative function.

Background: Intractable bleeding from the apical cannulation site of a left ventricular assist device (LVAD) is a dreaded complication. Case report: A 52-year-old male suffering from dilative cardiomyopathy (DCM) with fixed pulmonary hypertension underwent reoperative LVAD implantation after previous mitral valve surgery. The patient underwent three rethoracotomies for bleeding from the apex cannulation site without achieving hemostasis. Conventional techniques and application of fibrin sealants and polymeric sealing devices did not fix the problem. The bleeding stopped after application of the EVARREST® Fibrin Sealant Patch (FSP), and he needed no further transfusions. Conclusion: This patch might become a useful tool for intractable bleeding problems in LVAD surgery.
