Summary

Arrhythmogenic right ventricular dysplasia (ARVD) is a progressive heart condition causing sudden cardiac death in young athletes. Early diagnosis requires high suspicion for ventricular arrhythmias and family history, as initial tests may be negative.

Area of Science:

  • Cardiology
  • Genetics
  • Electrophysiology

Context:

  • Arrhythmogenic right ventricular dysplasia (ARVD) is a heritable heart muscle disease.
  • Characterized by fibrofatty replacement of the right ventricular myocardium.
  • Often presents with ventricular arrhythmias or sudden cardiac death, particularly in young individuals.

Purpose:

  • To outline diagnostic modalities for ARVD.
  • To discuss differential diagnoses.
  • To highlight the significance of ARVD in young, active athletes.

Summary:

  • Diagnostic challenges include potentially negative initial tests (ECG, echocardiography, biopsy).
  • Key ECG findings: inverted T waves (V1-V3), widened QRS (V1).
  • Echocardiographic and invasive findings: right ventricular dilation, reduced ejection fraction, fibrofatty infiltration.

Impact:

  • Emphasizes the need for high clinical suspicion in athletes with activity-related ventricular tachycardia/fibrillation and family history.
  • Early identification and management are crucial to prevent sudden cardiac death.
  • Understanding ARVD's genetic basis and presentation in athletes improves patient outcomes.
