Evaluation of the Valiant Mona LSA Thoracic Stent Graft System in Thoracic Aortic Aneurysms and Chronic Dissections

The Valiant Mona LSA device is a modular two-component system consisting of a main stent graft (MSG) and a branch stent graft (BSG), delivered separately, designed to maintain LSA perfusion. Briefly, under general anesthesia and after heparin injection, a MSG access is achieved via a femoral artery. A Through-and-through wire access for delivery of the BSG is achieved via a brachial artery. After the placement of the main aortic stent graft in the arch with the cuff at the level of the ostium of the LSA, the BSG is placed through a femoral access.
