Arrhythmogenic Right Ventricular Dysplasia (ARVD)

Overview

Arrhythmogenic Right Ventricular Dysplasia (ARVD) is a rare genetic heart condition that weakens the muscle in the right side of the heart. This thinning makes the heart more prone to irregular heartbeats (arrhythmias), which can sometimes cause the heart to pump poorly. ARVD can affect people of any age and is one of the top causes of sudden cardiac arrest in young people.

Symptoms

Symptoms of ARVD can vary and may include:

  • Heart palpitations or a racing heartbeat (tachycardia)
  • Feeling dizzy or lightheaded
  • Shortness of breath, especially during exercise
  • Chest pain
  • Fainting (syncope)
  • Swelling in the legs, ankles, or belly
  • Fatigue or weakness

Causes

ARVD is mostly caused by genetic mutations that affect how heart cells stick together. These mutations can be passed down from a parent or can happen on their own. Factors that can increase the risk include:

  • A family history of ARVD or sudden cardiac arrest
  • Certain viral infections that affect the heart
  • Intense physical activity, which may bring out symptoms in those with ARVD

Diagnosis

Diagnosing ARVD requires a mix of tests, such as:

  • A physical exam and medical history
  • Electrocardiogram (ECG) to check the heart’s electrical activity
  • Echocardiogram to see the heart’s structure
  • Cardiac MRI to take detailed pictures of the heart
  • Holter monitor to track heart rhythms over time
  • Genetic testing to find mutations linked to ARVD

Treatment Options

At Gertrude’s Children’s Hospital, we offer several ways to manage ARVD and reduce complications, including:

  • Medications to control heart rhythm, lower the risk of blood clots, and manage heart failure symptoms
  • Implantable Cardioverter Defibrillator (ICD) to monitor the heart and deliver electrical shocks if needed to restore normal rhythm
  • Catheter Ablation to destroy the small parts of the heart causing irregular rhythms
  • Lifestyle Changes like avoiding strenuous exercise to prevent arrhythmias
  • Heart Transplant in very severe cases where other treatments don’t work

Arrhythmogenic Right Ventricular Dysplasia (ARVD) in Children

Long-term effects may include recurring arrhythmias, heart failure, and an increased risk of sudden cardiac arrest. Regular monitoring and proper care can help reduce these risks.

ARVD is diagnosed using physical exams, imaging tests like echocardiograms and cardiac MRIs, and electrical activity monitoring with ECGs or Holter monitors.

Treatments include medications, ICDs, catheter ablation, lifestyle changes, and in some cases, heart transplant.
