This study aimed to determine the cumulative incidence of AS progression and associated factors in these patients. This retrospective cohort study included patients with cancer, mild or moderate AS and at least two echocardiograms 6 months apart between 1996 and 2016 at MD Anderson Cancer Center.

Patent Foramen Ovale With Platypnea - Orthodeoxia Syndrome: A Case Report.
