Pulmonary Vein Extension for Large Left Atrium Size Mismatch during Heart Transplantation.

Ann Thorac Surg 2022 Jun 22. Epub 2022 Jun 22.

Department of Thoracic and Cardiovascular Surgery, Gil Medical Center, Gachon University College of Medicine, Incheon, South Korea. Electronic address:

In cases with very large recipient left atrium (LA) sizes, matching the donor and recipient anastomoses can be challenging. In the presented case, this is addressed by reducing the circumference of the recipient's LA cuff by extending the pulmonary veins. The inferior pulmonary veins were extended by making neo-pulmonary veins using the remnant recipient's LA cuff, then the circumference of the recipient's LA cuff could be reduced to easily anastomosis.

Updated Views on Neutrophil Responses in Ischemia-Reperfusion Injury.

Transplantation 2022 Jun 24. Epub 2022 Jun 24.

Department of Surgery, Washington University School of Medicine, Saint Louis, MO.

Ischemia-reperfusion injury is an inevitable event during organ transplantation and represents a primary risk factor for the development of early graft dysfunction in lung, heart, liver, and kidney transplant recipients. Recent studies have implicated recipient neutrophils as key mediators of this process and also have found that early innate immune responses after transplantation can ultimately augment adaptive alloimmunity and affect late graft outcomes. Here, we discuss signaling pathways involved in neutrophil recruitment and activation after ischemia-mediated graft injury in solid organ transplantation with an emphasis on lung allografts, which have been the focus of recent studies.
