===Echocardiography===
===Echocardiography===
Echocardiography is essential for diagnosis and must exclude other diseases with predominantly right heart pathology, such as atrial septal defect (ASD), cor pulmonale and tricuspid dysplasia.
Marked right ventricular eccentric hypertrophy (increased end-diastolic diameter) and right atrial dilation are the most readily recognised abnormalities in ARVC. There may be right ventricular aneurisms and abnormal muscle trabeculations in the right ventricular apex. Increased right ventricular diastolic pressure leads to the interventricular septum bowing and flattening (paradoxical septal motion).
There may be left atrial dilation in some cats with ARVC because end-stage disease may also effect the left ventricle and left atrium.
==== Two Dimensional and M-mode====
* Right ventricular dilation +/- aneurismal thinning (thinning of the myocardial wall, usually at the apex)
* Right ventricular hypokinesia
* Right atrial enlargement
====Doppler====
* Mild tricuspid regurgitation
