A mitral prosthesis, when implanted, can distort the aortic annulus, forcing to downsize the aortic prosthesis. Changing the sequence of tying the sutures (the aortic prosthesis first, then the mitral prosthesis) allows to insert an aortic true-sized prosthesis. In case of associated tricuspid valve surgery, the aortic prosthesis protrudes over ...

Large left-sided pancreatic tumors are frequently associated with portal vein (PV) and/or superior mesenteric vein (SMV) occlusion. Traditionally, vein reconstruction is deferred until after removal of the tumor. However, division of venous collaterals, as is done in a typical left-to-right fashion, leads to progressive portal hypertension and increased risk of ...
