What is Aortic Dissection?

Aortic dissection is a serious condition where a tear occurs in the inner layer of the aorta, causing blood to flow between the layers of the aortic wall, which can lead to rupture or organ damage. It is classified into Type A (involving the ascending aorta, often requiring emergency surgery like the Bentall procedure) and Type B (involving the descending aorta, often managed with TEVAR endovascular stent-graft). Prompt diagnosis and treatment are critical, as the condition is life-threatening without intervention.
