Prevalence of right ventricular dysplasia-cardiomyopathy in a non-referral hospital.
In a cardiological department of a non-referral hospital responsible for 80,000 inhabitants with 2500 in-hospital patients and 1500 out-hospital patients per year, the prevalence, symptoms and prognosis of arrhythmogenic right ventricular dysplasia-cardiomyopathy (ARVD/C) were examined retrospectively. From 1997 to 2002, ARVD/C was diagnosed in 35 females and 45 males (overall prevalence 1 in 1000 inhabitants) with a mean age of 45.6 years. Symptoms were chest pain (80%), palpitations (60%) and syncopes (30%), and clinical findings were repetitive ventricular premature beats (50%), supraventricular arrhythmias (30%), ventricular tachycardia (20%), aborted sudden death due to ventricular fibrillation (1%), right heart failure (4%), biventricular heart failure (1%) and high grade AV nodal block (4%). Endomyocardial biopsies were not performed. Aborted sudden death occurred in only one patient (0.3%) before the diagnosis was made, annual heart failure rate was 1%. No deaths appeared in a follow-up of 1-5 (mean 2.4) years with clinical assessment as the basis of diagnosis. The prevalence of ARVD/C is much higher and the prognosis better than expected from results of reference centers.
