Insights

Donation after circulatory-determined-death (DCD) heart transplantation is increasing. A new technique uses normothermic regional perfusion for assessment before cold storage, enabling successful DCD heart transplants.

Area of Science:

  • Cardiology
  • Transplantation Medicine
  • Surgical Innovation

Background:

  • Donation after circulatory-determined-death (DCD) heart donation offers a potential to expand the donor pool for heart transplantation.
  • Established DCD heart retrieval methods include direct procurement with cold storage, direct procurement with machine perfusion, and normothermic regional perfusion (NRP) with transport perfusion.

Purpose of the Study:

  • To present a novel technique for DCD heart retrieval and transplantation.
  • To demonstrate the feasibility of using NRP for functional assessment of DCD hearts prior to transplantation.

Main Methods:

  • The study employed a technique involving normothermic regional perfusion (NRP) for DCD hearts.
  • This NRP phase allowed for functional assessment of the retrieved heart.
  • Following assessment, the heart was preserved using cold storage for transplantation.

Main Results:

  • Successful DCD heart transplantation was achieved using the described technique.
  • The method allowed for pre-transplant functional evaluation of the donor heart.
  • This approach expands the options for utilizing DCD hearts in transplantation.

Conclusions:

  • Normothermic regional perfusion followed by cold storage is a viable method for DCD heart retrieval.
  • This technique facilitates functional assessment, potentially improving outcomes in DCD heart transplantation.
  • The described approach contributes to increasing the utilization of DCD donors for heart transplantation.

Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Anatomy of the Heart01:27

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Determining the pH of Salt Solutions04:08

Determining the pH of Salt Solutions

The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution.  In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7. For...

Cold Weather Concreting01:27

Cold Weather Concreting

When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.
To counteract the negative impacts of cold weather, ensuring...
