Metabolic Considerations in Direct Procurement and Perfusion Protocols with DCD Heart Transplantation
The article by Maria Arnold et al. provides an in-depth analysis of the metabolic challenges and considerations involved in heart transplantation using donation after circulatory death (DCD) donors. This transplantation method is increasingly recognized for its potential to enhance donor heart availability and deliver excellent patient outcomes. However, it presents unique challenges compared to traditional…

Case Report: Anaphylactic Shock Induced by Human Fibrinogen Infusion During Cardiac Surgery
Human fibrinogen (FIB) is widely recognized for its efficacy in treating postoperative bleeding, particularly in cardiac surgery. Allergic reactions to human FIB are notably rare, making this case of anaphylactic shock during cardiac surgery a significant occurrence. This report details the case of a 27-year-old patient with rheumatic heart valve disease who underwent mitral valve…

Understanding Neutrophils in ECMO: Uncovering Their Role in Acute Organ Injury and New Therapeutic Avenues
The recent article by Mingfu Zhang and Colleagues, published in Frontiers in Immunology, presents a detailed exploration of the role of neutrophils in the acute organ injury often seen in patients undergoing extracorporeal membrane oxygenation (ECMO). ECMO is a life-saving intervention used for critically ill patients when conventional treatments are insufficient. While ECMO can stabilize…

Platelet function is Preserved After Moderate Cardiopulmonary Bypass Times But Transiently Impaired After Protamine.
A recent study led by Mattias Törnudd and colleagues has provided new insights into the effects of cardiopulmonary bypass (CPB) on platelet function in the context of contemporary cardiac surgery. This prospective, controlled clinical study was conducted at a single-center university hospital, including 39 patients scheduled for coronary artery bypass graft surgery with CPB. The…

Minimal Invasive Extracorporeal Circulation: An Alternative to ECMO in Ventricular Tachycardia Ablation
The clinical benefits of mechanical assistance during ventricular tachycardia (VT) ablation have yet to be well-established. This article discusses a new technique using minimally invasive extracorporeal circulation (MiECC) type III with a venous reservoir system, offering full cardiac flow support, blood oxygenation, and hemodynamic stability during extended procedures. The study retrospectively examines ten patients with…

Premortem Anticoagulation Timing and Dose in Donation After Circulatory Death Multicenter Study of Associations With Graft Function
This multicenter study led by Andreas H. Kramer and his colleagues delves into the critical practice of administering premortem heparin to potential organ donors in controlled donation after circulatory determination of death (DCD). Despite its widespread use, the practice remains controversial due to the potential risk of inducing bleeding and the lack of solid evidence…

Effects of Ketone Body 3-Hydroxybutyrate on Cardiac and Mitochondrial Function During Donation After Circulatory Death Heart Transplantation
A study led by Jacob Marthinsen Seefeldt et al. explored the impact of the ketone body 3-hydroxybutyrate (3-OHB) on cardiac and mitochondrial function in the context of heart transplantation following circulatory death. The research utilized normothermic regional perfusion (NRP) to assess the effects of therapeutic interventions in donor pigs, which were later transplanted into recipient…

Ethical Choices in Organ Transplantation: Why Normothermic Machine Perfusion is Preferable to NRP
The article titled “Neither Ethical nor Prudent: Why Not to Choose Normothermic Regional Perfusion” by Adam Omelianchuk, published in The Hastings Center Report, critically examines the ethical dilemmas posed by the use of Normothermic Regional Perfusion (NRP) in organ transplantation, specifically in the context of Donation after Circulatory Determination of Death (DCD). NRP is a technique used to…

Optimizing PEEP Management in Severe ARDS: The Role of Prone Positioning and ECMO
In the review article titled “Positive End-Expiratory Pressure Management in Patients with Severe ARDS: Implications of Prone Positioning and Extracorporeal Membrane Oxygenation,” authored by Christoph Boesing and colleagues and published in Critical Care, the ongoing challenge in managing severe acute respiratory distress syndrome (ARDS) revolves around determining the optimal strategy for titrating positive end-expiratory pressure…

Efficient and Safe Aorta Cannulation in Organ Donation After Cardiac Death
Mohamed Abdullah et al. present an efficient and safe technique for cannulating a depressurized aorta during organ donation after cardiac death, utilizing thoracoabdominal normothermic regional perfusion (NRP). The procedure, performed with informed written consent from donors’ families and without needing institutional review board approval, begins after an independent physician declares death and a mandatory standoff…

Simultaneous Pancreas and Kidney Transplantation from Donors after Circulatory Death in Switzerland
A recent study by Fabian Rössler and colleagues reports the first simultaneous pancreas and kidney transplantation (SPK) from donors after circulatory death (DCD) in Switzerland. This procedure is a critical advancement for type I people with diabetes and end-stage kidney disease, as it offers a curative treatment and expands the organ donor pool. SPK is…

Normothermic Regional Perfusion in Donor Heart Recovery: Establishing a New Normal
The article discusses the evolving landscape of heart transplantation, mainly focusing on using Normothermic Regional Perfusion (NRP) in donor heart recovery. With the scarcity of heart donors being a persistent issue, the medical community has been exploring innovative ways to expand the donor pool, including using hearts from donors who are not brain-dead, a process…
