This section delves into the concept of Donation After Circulatory Determination of Death (DCDD) as a way to tackle the severe shortage of organs for transplantation. It explains the key differences between DCDD and traditional Donation after Brain-Death (DBD) and how they help address the organ shortage. The section also outlines the criteria for selecting suitable DCDD donors and discusses the two main types of DCDD, along with the ethical considerations and protocols for each type. The focus then shifts to thoracic organs, specifically lungs and increasingly hearts due to advancements in the field. It highlights the challenges of warm ischemia time in traditional DCD and delves into recent breakthroughs in organ preservation techniques. These include Ex-situ perfusion with EVLP (static), EVLP (mobile) such as TransMedics OCS, and NRP, as well as advancements in transportation using devices like Paragonix Lung guard. These advancements pave the way for the potential expansion of DCD transplantation.
