title: Clinical picture of arrhythmogenic right ventricular dysplasia / cardiomyopathy patients from Indian origin.
abstract: OBJECTIVE
  Among the inherited cardiomyopathies, Arrhythmogenic right ventricular dysplasia/cardiomyopathy is unique with a peculiar pathology of fibro-fatty replacement. Studies have been carried out all over the world and several groups have reported clinical heterogeneity in manifestation of ARVD/C related symptoms. Present study is an attempt to identify the clinical profile of ARVD/C patients from Asian Indian origin.
  
  
  METHODS
  31 patients in the span of three years were diagnosed with ARVD/C. Diagnosis was based on proposed task force criteria.
  
  
  RESULTS
  The mean age at diagnosis was 32.9 +/- 16.4 years with slight tilt in male to female ratio (1.46). About 80% cases had palpitations, syncope in 45.16% and dyspnea in 22.5%, whereas 16% of patients were asymptomatic. About 50% of patients revealed a family history of confirmed ARVD/C or sudden death of a family member without any known cause. ECG showed T-wave inversion in about 60% cases, prolongation of QRS was observed in 20% cases. RV dilatation was observed in 80% of patients and 66.7% showed systolic dysfunction. RV free wall motion abnormalities were found in 33% patients. Most of the early onset cases with less than 30 years of age showed family history indicative of ARVD/C. Familial study in three patients indicated early onset of condition in younger generations in two families.
  
  
  CONCLUSIONS
  ARVD/C in India shows relatively early age at onset when compared with other Asian populations with more than half of patients showing the disease below the age of 30 years. History in most of the early onset cases revealed family history indicating strong genetic influence.
