Aortic Dissection

Brief summary

This is an observational study that establishes a cohort of patients with high risk chest pain who have been identified by CTA for aortic dissection. We then used this cohort to validate the accuracy of identifying aortic dissection based on extremity oximetry and Doppler waveforms.
