Arrhythmogenic right ventricular historical perspective
Overview
Historical perspective
- In 1977, the concept of a specific RV cardiomyopathy was first suggested in a report of six patients with sustained ventricular tachycardia (VT) and enlarged right ventricles
- Arrhythmogenic right ventricular cardiomyopathy (ARVC) was described for the first time by Frank and Fontaine in 1978[1]
- It was first described in patients undergoing surgical ablation for right ventricular outflow tract (RVOT) tachycardia
- In 1982, the term “arrhythmogenic right ventricular dysplasia” was first used in a case series of 24 patients with left bundle branch block (LBBB) pattern VT, RV wall motion abnormalities and replacement of the RV myocardium by adipose and fibrous tissue[2]
- The term arrhythmogenic right ventricular dysplasia was not formally recognized as a distinct entity until 1994, following the publication of diagnostic criteria by the World Health Organization/International Society and Federation of Cardiology Task Force[3]
- In 1994, diagnostic criteria were published by the Working Group on Myocardial and Pericardial Diseases of the European Society of Cardiology and the Scientific Council on Cardiomyopathies of the International Society and Federation of Cardiology
- In 2010, these criteria were modified
- The first gene mutations linked to the disease were identified in a recessive, syndromic variant of ARVC known as Naxos disease.
- The cause of this particularly malignant form of the condition was found to be a two-base pair deletion in the gene encoding plakoglobin, a major component of cell-to-cell junctions[4]
- Disease-causing mutations in other genes encoding desmosomal proteins in the more common autosomal dominant forms of ARVC were then identified[5][6]
- Latter on, very similar clinical and histological phenotypes have been identified in patients with mutations in non-desmosomal genes, including titin, desmin and lamin A/C
