What is the link between Aortic Dissection and Cardiac Tamponade?

Can you explain the link between aortic dissection and cardiac tympanad? So type A dissection arises normally from a entry of blood between the intima and the media layers of the aorta in the ascending aorta or in the arch. The direction of blood flow is from the heart through the arch down into the descending aorta. heart. Sometimes when blood gets into this layer, it will track backwards. It will dissect down towards the heart. It will go behind the intima and then it will get into the, what we call the pericardium, which is effectively a bag that surrounds the heart with an outside and inside layer. The job of this bag usually is to allow the heart to move around the chest with a sort of protection in a in the in a sort of sack which has a small amount of fluid in it which is vital for this it's called pericardial fluid. If blood gets into this there's nowhere for it to go so blood will fill this sack and if there is a high enough pressure it will compress the heart so there's only so much that this bag can stretch so what will give eventually is the heart itself that the heart will be slowly compressed until either the blood stops flowing in or the heart itself stops beating.
