Arrhythmogenic right ventricular dysplasia (ARVD) is increasingly recognized as a cause of sudden cardiac death in young adults, often linked to genetic factors on chromosome 14. Treatment options range from antiarrhythmic drugs to advanced interventions like defibrillators and heart transplantation.

Area of Science:

  • Cardiology
  • Genetics
  • Pathology

Background:

  • Arrhythmogenic right ventricular dysplasia (ARVD) is a recognized clinical entity.
  • It is increasingly identified as a cause of sudden unexpected death in young adults.
  • Familial cases suggest a genetic transmission, with a locus on chromosome 14 implicated.

Purpose of the Study:

  • To review the clinical recognition, genetic basis, and therapeutic strategies for arrhythmogenic right ventricular dysplasia.
  • To highlight the diagnostic features and management of this progressive cardiac condition.

Main Methods:

  • Systematic review of electrocardiogram (ECG) findings in ARVD patients.
  • Analysis of genetic transmission patterns in familial cases.
  • Evaluation of current therapeutic approaches.

Main Results:

  • ECG studies reveal QRS prolongation and repolarization abnormalities in right precordial leads due to parietal block.
  • A genetic locus on chromosome 14 is associated with ARVD.
  • Inflammatory processes can exacerbate ARVD, leading to left ventricular dysfunction.

Conclusions:

  • ARVD is a significant cause of sudden cardiac death, with a genetic basis.
  • Effective management involves antiarrhythmic drugs, with ablative techniques, defibrillators, and transplantation for severe cases.
