Definitions for "Aortic Dissection"
The aorta is the main blood vessel leaving the heart and providing blood flow to the rest of the body. This blood vessel is made up of many layers. In certain circumstances, a tear develops in the middle layer, which allows blood to travel down the layer, setting up two channels - the "true" lumen or opening through the blood vessel and the new "false" lumen. Aortic dissection can be a life-threatening emergency, in some situations requiring emergency surgery to repair or replace that segment of the aorta.
Division of the aorta into a number of smaller vessels.
a disease characterized by tear of aortic intima, hematoma formation and separation of the arterial wall
an excellent alternative to the mechanical valve replacement that requires consequent anticoagulation, and which may interfere with thrombosis of the residual false lumen
