Presentation of Asymptomatic Ebstein's Anomaly: A Case Report

Area of Science:

• Cardiology
• Congenital Heart Disease

Background:

• Ebstein's anomaly (EA) is a rare congenital heart defect characterized by displacement of the tricuspid valve.
• EA typically presents in infancy or childhood, but late-onset presentations are possible.

Observation:

• A 58-year-old man with a history of Ebstein's anomaly diagnosed in infancy presented with new-onset dyspnea, palpitations, dizziness, and fatigue during exercise.
• These symptoms began at age 55, indicating a late-onset manifestation of EA complications.

Findings:

• The patient experienced acute symptoms consistent with right-sided heart failure and potential arrhythmias, common risks associated with Ebstein's anomaly.
• This case is unique due to the late development of symptomatic complications in an individual diagnosed with EA early in life.

Implications:

• Highlights the importance of long-term monitoring for asymptomatic Ebstein's anomaly patients.
• Emphasizes the need to recognize the diverse clinical spectrum and potential for late-onset complications in adult congenital heart disease.
• Underscores the necessity of timely intervention for progressing Ebstein's anomaly to prevent severe outcomes like heart failure and sudden cardiac arrest.
