Arrhythmogenic right ventricular cardiomyopathy (ARVC) is
a rare inherited cardiomyopathy characterised by right
ventricular dysfunction, ventricular arrhythmias and increased
risk of sudden cardiac death. Due to the replacement of
myocardium with fibro-fatty and fibrous tissue, patients with
ARVC are prone to develop ventricular tachycardia.
Histologically, it is often reported as the ‘triangle of dysplasia’
involving the inflow tract, outflow tract and apex of the right
ventricle.2 We describe a 20-years-old patient who collapsed
during a futsal match and was subsequently diagnosed to have
ARVC with a right ventricular thrombus from cardiac
magnetic resonance imaging.
