Charcot—Marie—Tooth disease 2A Hereditary spastic paraplegia Long QT syndrome 4. Ventricular arrhythmias are usually exercise-related, suggesting that they are sensitive to catecholamines. Because of this, every attempt is made at placing the defibrillator lead on the ventricular septum. Spinocerebellar ataxia 5 Hereditary spherocytosis 2, 3 Hereditary elliptocytosis 2, 3 Ankyrin: Paradoxical septal motion may also be present. If the left ventricle is involved, it is usually late in the course of disease, and confers a poor prognosis.

Residual myocardium is confined to the subendocardial region and the trabeculae of the RV. It is unclear why only the right ventricle is involved. Atrial flutter Ventricular flutter Atrial fibrillation Familial Ventricular fibrillation.

From Wikipedia, the free encyclopedia. Fitzpatrick’s Dermatology in General Medicine. This may lead to undersensing of the individual’s electrical activity potentially causing inability to sense VT or VFand inability to pace the ventricle. In order to make the diagnosis of ARVD, a number of clinical tests are employed, including the electrocardiogram EKGechocardiographyright ventricular angiography, cardiac MRI, and genetic testing.

Please help improve this article by adding citations to reliable sources. The diagnosis of ARVD is based on a combination of major and minor criteria. Views Read Edit View history. D ICD – The second, fibro-fatty infiltration, involves replacement of myocytes with fibrofatty tissue. Retrieved from ” didplasia This page was last edited on 4 Novemberat However, this is arritmobenica non-specific finding, and may be considered a normal variant in right bundle branch block RBBBwomen, and children under 12 years old.


While this is a genetically transmitted disease, individuals in their teens may not have any characteristics of ARVD on screening tests. In other projects Wikimedia Commons. There is no pathognomonic feature of ARVD. Arritmoggenica Nephrogenic diabetes insipidus 2. Many individuals have symptoms associated with ventricular tachycardia, such as palpitations, light-headedness, or syncope. Ventricular arrhythmias due to ARVD typically arise from the diseased right ventricle.

Hypertrophic cardiomyopathy 7, 2 Nemaline myopathy 4, 5. Archived from the original arritmohenica Endocarditis infective endocarditis Subacute bacterial endocarditis non-infective endocarditis Libman—Sacks endocarditis Nonbacterial thrombotic endocarditis.

Also, due to the paper-thin right ventricular free wall displwsia is common arrimtogenica this disease process, most biopsy samples are taken from the ventricular septum, which is commonly not involved in the disease process. The left ventricle and ventricular septum are usually spared. Signs and symptoms of left ventricular failure may become evident, including congestive heart failure, atrial fibrillation, and an increased incidence of thromboembolic events. It usually occurs in the diaphragmatic, apical, and infundibular regions known as the triangle of dysplasia.

The first clinical signs of ARVD are usually during adolescence.

However, the LV free wall may be involved in some cases. February Learn how and when to remove this template message. ARVD is an autosomal dominant trait with reduced penetrance. Andrews’ Diseases of the Skin: Echocardiography may reveal an enlarged, hypokinetic right ventricle with a paper-thin RV free wall.


A certain subgroup of individuals arritkogenica ARVD are considered at high risk for sudden cardiac death.

Arrhythmogenic right ventricular dysplasia – Wikipedia

This is used to establish the pattern of inheritance. To make a diagnosis of ARVD requires either 2 major criteria or 1 major and 2 minor criteria or 4 minor criteria. ARVD is caused by genetic defects of the parts of heart muscle also called myocardium or cardiac muscle dizplasia as desmosomesareas on the surface of heart muscle cells which link the arritmoyenica together.

Heart transplant may be performed in ARVD. ARVD can be found in association with diffuse palmoplantar keratodermaand woolly hairin an autosomal recessive condition called Naxos diseasebecause this genetic abnormality can also affect the integrity of the superficial layers of the skin most exposed to pressure stress.

Arrhythmogenic right ventricular dysplasia

Catheter ablation may be used to treat intractable ventricular tachycardia. The areas involved are prone to aneurysm formation.

While angiotensin converting enzyme inhibitors ACE Inhibitors are well known for slowing progression in other cardiomyopathies, they have not been proven to be helpful in ARVD.

Surfactant metabolism displwsia 1, 2.

It may be indicated if the arrhythmias associated with the disease are uncontrollable or if there is severe bi-ventricular heart failure that is not manageable with pharmacological therapy. Sinus bradycardia Sick sinus syndrome Heart block: This is described as a terminal notch in the QRS complex.
