Endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) are minimally invasive procedures to treat abdominal, and many thoracic, aortic aneurysms. An aneurysm, an abnormal bulge or ballooning in the wall of a blood vessel, can burst which causes bleeding inside the body and often leads to death. [1]

Although diagnostic of MI, it is highly suspicious for " Old inferior MI with persistent ST Elevation" or "inferior aneurysm morphology" because of the well-formed Q-waves and the flat T-waves. To repeat: in contrast, anterior aneurysm is much more easily distinguished from acute MI due to the QS-waves.

While this may be change that is reciprocal to an Acute/Subacute Inferior STEMI, the problem is that LV aneurysm may also manifest with this reciprocal change. Old MI w/Aneurysm will show moderate ST Elevation, as seen here.

Once dissecting aneurysm was ruled out by chest aorta CT — the possibility of acute ischemic heart disease becomes paramount.
