What is an aortic aneurysm?

• A. Ballooning of the aorta, which can lead to rupture and requires immediate surgical intervention.
• B. Inflammation of the heart muscle.
• C. Narrowing of the aorta without rupture risk.
• D. A congenital defect causing valve leakage.

Answer: (A)

An aortic aneurysm is a localized dilation of the aorta caused by weakening of the vessel wall, which can occur in the chest or abdomen. The main danger is rupture, a life-threatening event that often requires urgent surgical repair, either open or via endovascular techniques, depending on factors like size and location. Smaller or stable aneurysms are monitored, while larger or rapidly enlarging ones are treated to prevent rupture.

The other descriptions refer to different heart conditions: inflammation of the heart muscle (myocarditis), narrowing of the aorta without rupture risk (aortic coarctation or aortic stenosis), and a congenital defect causing valve leakage (aortic regurgitation). The description of ballooning of the aorta that can rupture and may require immediate surgical intervention best fits an aortic aneurysm.
