ViTAA Registry Pre- and Post-Operative Monitoring for Endovascular Aortic Aneurysm Repair and Serial Monitoring for AAA

This a prospective, multi-center, registry of patients that are being assessed with the ViTAA software. Patients will be enrolled at selected North American centers in the US and Canada. The Registry will enroll patients from the following two populations: * patients who are scheduled and ultimately receive endovascular infrarenal aortic aneurysm repair (EVAR); * patients who do not yet qualify for infrarenal aortic aneurysm repair based on anatomic size criteria who are enrolled in a serial monitoring program.
