Although papillary chord abnormalities are most commonly seen in patients with hypertrophic cardiomyopathy (HCM), there are rare case reports in the literature showing abnormal attachment of chordates to the basal septum, causing serious gradients in patients without HCM. In this case, we present a 54-year-old male patient with no diagnosis of HCM, who was diagnosed with strange and unusually abnormal chordae tendons, subaortic sac, and persistent left superior vena cava.
