Background: Non-bacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis or Libman-Sacks endocarditis, is a rare non-infectious condition affecting mostly the left-sided heart valves of patients who, most often, suffer from malignancies and connective tissue disorders. Herein, we present a case of a male patient with marantic endocarditis due to occult lung adenocarcinoma.
Case Presentation: The patient fulfilled the modified Duke's criteria of possible bacterial endocarditis of the aortic valve; however, multiple blood cultures and serological tests were negative.
The frozen elephant trunk is a formidable tool for the aortovascular surgeon. An appreciation of how to size the graft in different pathologies is key in achieving optimal results. Herein, we demonstrate worked examples of how imaging can be used to plan for a frozen elephant trunk and discuss the nuisances and uncertainties of sizing using three index cases: Type A aortic dissection, distal thoracic aortic aneurysm and chronic dissection.

Although blunt thoracic aortic injury commonly occurs at the aortic isthmus or descending thoracic aorta, we encountered a 36-year-old male patient with Grade III blunt aortic injury located in the mid-arch. An endovascular approach was not feasible and thus the patient underwent total arch replacement using the frozen elephant trunk technique.

The E-Vita OPEN NEO hybrid stent graft system offers a unique approach for aortic arch replacement with the frozen elephant trunk technique. In contrast to its predecessors and other commercially available devices, it fits to each individual patient's needs by allowing for more proximal graft anastomosis.
