Key result
Cardiac MRI revealed fatty replacement in the right ventricular myocardial tissue and apical hypokinesia, leading to a diagnosis of borderline ARVD in a 74-year-old patient.
Case Report (n=1)
This case report demonstrates that ARVD, typically considered a disease of young adults, can present and be diagnosed in the elderly using standard diagnostic criteria and cardiac MRI.
ARVD may occur in the elderly; hypothesis-generating and leaves open need for age-specific validation.
Arrhythmogenic right ventricular dysplasia (ARVD) is a type of nonischemic cardiomyopathy which primarily involves the right ventricle (RV). ARVD is considered a major cause of sudden death in young adults, mainly in the age group under thirty years old and is rarely found in the elderly. Males are predominantly affected.1-3 ARVD has been proposed as a genetic inherited disease with autosomal dominant and various penetrance patterns.4, 5 ARVD is pathologically characterized by fibro-fatty or fatty replacement of the right ventricular myocardial tissue. The fatty form is presented by almost complete replacement without endocardial thinning and found almost exclusively on the RV myocardium. The fibro-fatty replacement is defined as a fatty replacement with endocardial thinning less than 3 mm thickness6.

Arunakul et al. (2012) conducted a case report in Arrhythmogenic Right Ventricular Dysplasia (ARVD) (n=1). Cardiac MRI was evaluated on Diagnosis of ARVD. Cardiac MRI revealed fatty replacement in the right ventricular myocardial tissue and apical hypokinesia, leading to a diagnosis of borderline ARVD in a 74-year-old patient.
