Combined en bloc heart and liver organ procurement

Abstract

A combined heart+liver transplant is the only option for survival in some patients with end-stage combined cardiac and hepatic disease. These patients may suffer from congenital or acquired cardiac disease. The potential aetiologies of the associated hepatic disease are heterogeneous and include systemic disease that impacts the liver as well as venous congestion in patients with functionally univentricular circulation. In the latter scenario, patients with functionally univentricular circulation often require complex cardiac reconstruction in the setting of a cardiac transplant after staged palliation. During cardiac procurement, our approach is to dissect the entire ascending aorta and aortic arch in continuity; the entire superior caval vein and innominate vein in continuity; and the pulmonary arteries from hilum to hilum if the donor is not a candidate for recovery of the lungs. The cardiac and abdominal organ procurement teams work in parallel during dissection and combined en bloc cardio-hepatectomy. This technique minimizes exposure of both organs to cold ischaemia. This video tutorial demonstrates the key steps for combined en bloc heart+liver organ procurement.
