This study details a case of arrhythmogenic right ventricle (ARV) diagnosed in a young patient presenting with recurrent ventricular tachycardia and heart failure. Effective management involved a combination of medications and cardiac pacing.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Genetics

Background:

  • Arrhythmogenic right ventricle (ARV) is a hereditary heart muscle disease.
  • It is characterized by fibrofatty replacement of the right ventricular myocardium.
  • ARV can lead to ventricular arrhythmias, heart failure, and sudden cardiac death.

Observation:

  • A 26-year-old patient presented with recurrent ventricular tachycardia and dextrolateral cardiac failure.
  • Other potential causes including pulmonary embolism, ischemic heart disease, and Ebstein's anomaly were excluded.
  • Diagnostic findings included negative T waves in V1-V3 during sinus rhythm and specific QRS complex morphology during tachycardia.

Findings:

  • The diagnosis of arrhythmogenic right ventricle was established based on clinical presentation and diagnostic criteria.

  • Electrocardiography revealed characteristic T wave inversions and QRS abnormalities suggestive of right bundle branch block.
  • Angiography showed marked trabeculization and impaired right ventricular outflow tract kinetics, further supporting the ARV diagnosis.

    • Implications:

    • Simultaneous administration of beta-blockers, Cordarone, and cardiac stimulation (AAI) proved effective in preventing ventricular tachycardia relapses.
    • This case highlights the importance of early diagnosis and comprehensive management strategies for ARV.
    • Further research into genetic factors and long-term outcomes in ARV patients is warranted.
