Variants of<unk><unk>  ventricular<unk>  can be classified based on the the genetic abnormality involved; So far, 12 variants have been identified. Another classification was based on the clinical manifestation which was first developed by Fontaine et al. and lead to the identification of 3 clinical forms (based on a 9-year observation of 4 patients with different clinical course of ARVC). Later on, another variant of the ARVC classification was proposed, in which the RV and left ventricular forms were distinguished and a total of eleven different clinical forms were identified. However, these classifications did not define prognosis and approaches to treatment and hence, none was widely used in clinical practice. So, The development of clinical classification is considered an important task and an ultimate challenge.
