All of the blood flow leaving the left ventricle flows through some or all of the aorta. It carries oxygen-filled blood from the heart to different organs in the body. Screening means you have regular imaging tests, usually an echocardiogram, to check for an aneurysm. In situations where the bulge is small or not growing very fast, your cardiovascular specialist may simply recommend monitoring and screening rather than surgery.

Arch anomalies can be associated with symptoms, such as dysphagia lusoria in the setting of left aortic arch with aberrant right subclavian artery. However, some small and slow-growing aneurysms may never rupture. Finally, the left subclavian artery comes off of the aortic arch to the left of the left common carotid artery and ascends, with the left common carotid, through the superior mediastinum and along the left side of the trachea. This means as the aorta leaves the heart, it arches to the left side.
