    In Thoracoabdominal Normothermic Regional Perfusion (TA-NRP) for Donation after Circulatory Death (DCD), initiating central cannulation with a venous-first approach serves as a critical step to decompress an acutely distended heart, optimize hemodynamics, and protect both thoracic and abdominal organ quality. Following formal death declaration, a rapid median sternotomy..

    The scarcity of viable donor organs remains a restrictive bottleneck in thoracic transplantation. To expand the donor pool, transplant networks increasingly utilize "extended-criteria" or marginal donor lungs. However, brain-dead or circulatory-death donors exist in a hypercoagulable, prothrombotic state due to systemic inflammation, prolonged immobilization, and invasive central venous..

    Preoperative Diagnosis: Malignant lung tumor of the right lung with extensive invasion into the Right Pulmonary Artery (RPA) and the right-sided superior and inferior pulmonary veins.   Procedure performed: Right radical pneumonectomy, en bloc resection of invaded vascular structures, establishment of central Cardiopulmonary Bypass (CPB) via bicaval cannulation,..

    Surgical Procurement of a Donor Heart with Complex Congenital and Venous Anomalies: PLSVC, Coronary Sinus Dilation, RA Aneurysm, and Patent Ductus Arteriosus (PDA) In thoracic organ transplantation, discovering complex congenital and venous anomalies in a donor organ is a high-stakes scenario. While an isolated persistent left superior vena..

    Partial Heart and Lung Transplantation: Maximizing Donor Organ Utilization Through Two-Recipient Transplantation Partial heart and lung transplantation is an innovative organ utilization strategy that allows transplantation of thoracic organs from a single donor into two separate recipients. This approach aims to maximize the use of scarce donor organs..

      Managing aortic and pulmonary root enlargement in donor organs requires a meticulous, proactive strategy to ensure structural stability before implantation into an emergency recipient. Utilizing a double Personalized External Aortic Root Support (PEARS) approach with polytetrafluoroethylene (PTFE) mesh provides a tailored, non-reconstructive solution that stabilizes both the..
