EVALUATION OF THE VALIANT MONA LSA THORACIC STENT GRAFT SYSTEM IN DESCENDING THORACIC AORTIC ANEURYSMS AND CHRONIC DISSECTIONS

The trial involves an investigational device (not approved by the FDA) for subjects who have an aneurysm (bulge), dissection (tear) or a penetrating ulcer (bubble) of the descending aorta that involve an artery (main blood vessel in your body). The subject must need to have one of their blood vessels which comes off of the top of the aorta and feeds blood to your left chest, left arm and head re-routed so that the blood flow changes. The device has 2 parts. The first part is threaded through a vessel in your groin or lower abdomen up your aorta until your surgeon reaches the area to be treated. Once the device is in place another piece is threaded up the aorta and goes inside of the first stent and is place part way through a hole on the top of the first device and the end lands in the vessel leading to the head. This provide a new pathway for the blood to flow and repairing the aorta from inside of the vessel (endovascular repair).

You may be eligible for this study if you meet the following criteria:

• Conditions: THORACIC AORTIC ANEURYSMS AND CHRONIC DISSECTIONS
• Age: 99 years or below
• Gender: All
