Right ventricular dysplasia (RVD) often presents with various arrhythmias, not just ventricular tachycardia, and may affect older individuals more frequently. This condition might be an underlying cause for lone atrial fibrillation and sick-sinus syndrome.

Area of Science:

  • Cardiology
  • Pathology

Context:

  • Right ventricular dysplasia (RVD) involves fatty and fibrous tissue replacement of the right ventricle.
  • Traditionally, RVD presents with ventricular tachycardia in the fourth decade of life.

Purpose:

  • To investigate the clinical presentation and arrhythmia spectrum of RVD.
  • To determine if RVD affects an older population than previously reported.

Summary:

  • Echocardiography diagnosed RVD in 8 patients (6 men, 2 women, mean age 55.6 years) after excluding other causes of right ventricular enlargement.
  • Most patients presented with supraventricular arrhythmias (atrial flutter, atrial fibrillation, supraventricular tachycardia, sick-sinus syndrome), with only 2 experiencing ventricular tachycardia.
  • RVD may encompass a broader range of arrhythmias and affect older individuals, potentially including slowly developing forms.

Impact:

  • RVD's arrhythmia spectrum is wider than previously thought, with ventricular tachycardia not being the most common presentation.
  • The incidence of RVD may be underestimated in older populations.
  • RVD could be the underlying pathology for lone atrial fibrillation and sick-sinus syndrome in some cases.
