Heart-Associated Cytokine and Endothelial Patterns Dominate the Ischemia/Reperfusion Response in Recipients of Combined Heart/Lung Transplantation in Comparison to Lung Transplantation
F. Wandrer¹, B. Wiegmann², N. Ledwoch¹, R. Bellmas Sanz¹, F. Ius², W. Sommer², S. Rojas², C. Kühn², I. Tudorache², M. Avsar², A. Haverich², G. Warnecke², C. S. Falk¹
¹Institute of Transplant Immunology, Hannover Medical School, Hannover, Germany, ²Department for Cardiothoracic, Transplantation and Vascular Surgery, Hannover Medical School, Hannover, Germany
*Purpose: Organ-specific differences are discussed for ischemia/reperfusion injury (IRI) in cardiothoracic transplantation (Tx) but rarely compared directly in a clinical setting. Therefore, we compared a…
