ascending aorta การใช้

• This can cause dilatation and weakening of the walls of the ascending aorta.
• The truncus arteriosus splits into the ascending aorta and pulmonary artery.
• These individuals are prone to dissection in the ascending aorta.
• In those instances replacement of the ascending aorta ( so-called tubular aorta ) is sufficient.
• Pathology of the aortic valve, aortic root and ascending aorta are treated with the Bentall procedure.
• A septum begins to form between what will later become the ascending aorta and pulmonary tract.
• Type 2 refers to dissection of the ascending aorta, closer to and including the aortic arch.
• It usually then travels in front of the ascending aorta and then ends in a brachiocephalic node.
• Aneurysms in the ascending aorta may require surgery at a smaller size than aneurysms in the descending aorta.
• Type 1 encompasses dissection in the distal ascending aorta closest to the heart, not including the aortic arch.
• At the root of the ascending aorta, the posterior aortic sinus does not give rise to a coronary artery.
• In a proportion of the affected individuals an aneurysm of the ascending aorta may be present which may need treatment.
• BAV outflow is helical and occurs at high velocities ( > 1 m / s ) throughout the ascending aorta.
• Some patients with dissection of the ascending aorta have elevated troponins, and increased hemodynamic stress has been suggested as a mechanism.
• The aneurysm of the ascending aorta may also become so large that it can develop rupture or dissection as life-threatening complications.
• In half of the affected individuals there is also an aneurysm of the ascending aorta which has to be treated appropriately.
• The pump pushes the blood through a flexible Dacron graft ( invented decades ago by DeBakey ) sewn to the ascending aorta.
• It is a broad band of cardiac muscle that passes from the right atrium, between the superior vena cava and the ascending aorta.
• The enlargement of the ascending aorta may lead to aortic valve regurgitation because the outward tension on the cusps inhibits their adequate closure.
• Upon cardiac catheterization, catheters can be placed in the left ventricle and the ascending aorta, to measure the pressure difference between these structures.
