What is arrhythmogenic right ventricular dysplasia?

Arrhythmogenic right ventricular dysplasia / cardiomyopathy (ARVD/C) is a rare familial disorder that may cause ventricular tachycardia and sudden cardiac death in young, apparently healthy individuals. The clinical hallmark of the disease is ventricular arrhythmias, arising predominantly from the right ventricle.

How is arrhythmogenic right ventricular dysplasia diagnosed?

How is Arrhythmogenic Right Ventricular Dysplasia Diagnosed? ARVD is diagnosed based your on medical history, physical exam, and tests (echocardiogram, Holter monitor, electrophysiologic testing, cardiac MRI, and/or cardiac CT scan. Learn more about these tests.

Does ARVD show on echocardiogram?

Therapeutic options include antiarrhythmic medication, catheter ablation, implantable cardioverter defibrillation, and surgery. Angiography and echocardiography lack sensitivity and specificity in the diagnosis of ARVD.

What are symptoms of ARVC?

What are the symptoms of ARVC?

  • Fainting.
  • Heart palpitations with unpleasant awareness of the heartbeat.
  • Dizziness.
  • Shortness of breath with exertion or when lying down.
  • Chest pain.
  • Fatigue.
  • Swelling in the legs and other areas.
  • Persistent cough.

What causes arrhythmogenic right ventricular dysplasia?

Arrhythmogenic right ventricular dysplasia (ARVD) or cardiomyopathy (ARVC) is caused by several genetic defects, affecting desmosomes, which are proteins on the surface of heart muscle cells that link those cells together. These genetic defects lead to abnormalities in the lower heart chambers, the ventricles.

What is the treatment for ARVC?

Implantable cardioverter defibrillator placement is the only proven mortality benefit in treatment of ARVC. Other treatment strategies include medications such as beta blockers and antiarrhythmics, radiofrequency ablation, surgery, cardiac transplantation, and lifestyle changes.

How do you test for ARVC?

Diagnosing ARVC is challenging and requires a combination of diagnostic tests. Non-invasive testing testing may include an electrocardiogram to measure the heart’s electrical patterns and echocardiogram or cardiac magnetic resonance imaging (MRI) to visualize changes in the heart structure.

Is ARVC hereditary?

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare disease of the heart muscle. ARVC is a genetic condition, which can be inherited. This means it can be passed on through families. It is caused by a change or mutation in one or more genes.

How does ARVC affect my life expectancy?

We concluded that ARVC at locus ARVD5 is a lethal, fully penetrant, sex-influenced morbid disorder. Median life expectancy was 41 years in affected males compared to 71 years in affected females (relative risk 6.8, 95% CI 1.3–10.9). Heart failure was a late manifestation in survivors.

What does arrhythmogenic mean?

Medical Definition of arrhythmogenic : producing or tending to produce cardiac arrhythmia Digoxin should be used with caution, since it is potentially arrhythmogenic, particularly in patients with amyloidosis.— Sudhir S.

How is arrhythmogenic cardiomyopathy diagnosed?

Arrhythmogenic cardiomyopathy is diagnosed using both cardiac and genetic testing. A detailed family history can identify other family members who already are or may be affected.

What is Naxos syndrome?

Naxos disease is a recessive association of arrhythmogenic right ventricular cardiomyopathy (ARVC) with wooly hair and palmoplantar keratoderma or similar skin disorder.

What gene causes ARVC?

Researchers are working to determine how mutations in non-desmosomal genes can lead to ARVC. Gene mutations have been found in about 60 percent of people with ARVC. Mutations in a desmosomal gene called PKP2 appear to be most common. In people without an identified mutation, the cause of the disorder is unknown.

Is ARVD the same as ARVC?

Arrhythmogenic right ventricular dysplasia (ARVD), also known as arrhythmogenic right ventricular cardiomyopathy (ARVC), is a leading cause of sudden death among young athletes but it can affect people of all ages and all activity levels.

Can ARVC skip a generation?

Most often, ARVC is inherited in an autosomal dominant manner. This means that each child of a parent with ARVC has a 50% chance of inheriting the genetic mutation associated with the condition. The genetic mutation does not skip generations.

What are the symptoms of right heart failure?

What are the symptoms of right-sided heart failure?

  • shortness of breath, especially when lying flat.
  • coughing.
  • dizziness.
  • difficulty concentrating and confusion.
  • fatigue and low energy.
  • sudden weight gain.
  • reduced appetite.
  • upset stomach.

Can I exercise with ARVC?

For now, it is clear that competitive sports should be avoided in patients with ARVC. Participation in moderate- to high-intensity recreational sports is also discouraged. The recommendations for activity restrictions in asymptomatic gene carriers (genotype positive/phenotype negative) have less data.

What is arrhythmogenic effect?

An arrhythmogenic. effect of antiarrhythmic drug therapy was defined as the. spontaneous occurrence of a new symptomatic ventricular. tachyarrhythmia that occurred in temporal association with. the start of drug administration or a new increase in dosage.

How is arrhythmogenic right ventricular dysplasia treated?

ARVD can be treated with medicines. These include: Medicines to help prevent abnormal heart rhythms (antiarrhythmics) Medicines to control your heartbeat, such as beta-blockers. … Other possible treatments include:

  1. Catheter ablation. …
  2. Implantable cardioverter defibrillator (ICD). …
  3. Heart transplant.

Can you have a baby with ARVC?

These results suggest that most pregnancies of patients with ARVD/C are tolerated well. However, 13% of pregnancies were complicated by sustained ventricular arrhythmias and 5% by onset of heart failure.

Do I have ARVC?

Symptoms of ARVC/D include a strong or irregular heart beat (palpitations), chest pain, or shortness of breath. Symptoms can include palpitations, lightheadedness, fainting, or even cardiac arrest. Episodes can occur at any time, but are often associated with physical exertion.

Which of the following genes can cause ARVC when mutated?

Diagnosis/testing. The common genetic causes known to be associated with ARVC are: DSC2, DSG2, DSP, JUP, PKP2, and TMEM43. Less common genetic causes include CTNNA3, DES, LMNA, PLN, RYR2, TGFB3, and TTN. A subset of these 13 genes encode components of the desmosome.

Is cardiomyopathy cardiovascular disease?

Cardiomyopathy (kahr-dee-o-my-OP-uh-thee) is a disease of the heart muscle that makes it harder for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure. The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy.

Is arrhythmogenic cardiomyopathy genetic?

Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) is a rare, genetic disorder that causes ventricular arrhythmias which can increase the chance of death in young individuals.

Is cardiomyopathy a death sentence?

Normally, when people look up cardiomyopathy, they’re terrified by talk of a five-year life expectancy. That’s nonsense. As long as you’re diagnosed early, it’s definitely not a death sentence.

Can you drink alcohol with cardiomyopathy?

Among alcoholic patients with alcoholic cardiomyopathy, either abstinence or reduction of alcohol intake to about 1.5 to 6 drinks per day was associated with comparable improvement in left ventricular ejection fraction [30]. These limited data suggest that moderate drinking might confer some benefits among HF patients.
