Abstract
This report describes the case of a 58-year-old man with Ebstein's anomaly (EA) who remained asymptomatic until 55 years of age when he began experiencing acute dyspnea, palpitations, dizziness, and fatigue during exercise. Patients with EA have an increased risk for arrhythmia, right-sided heart failure, and sudden cardiac arrest. This case report highlights the late-onset complications of EA in a previously asymptomatic adult. While this case aligns with the typical collection of symptoms seen in EA, it is unique in that the complications of EA did not develop until the patient was an older adult despite being diagnosed with EA shortly after birth. However, the spectrum of clinical presentation of EA varies greatly from asymptomatic to severe. For patients with asymptomatic EA, this case exemplifies the importance of recognizing the progression and complications of this malformation in older adults to ensure proper interventions are pursued.
