Key Points
  • Restrictive cardiomyopathy (RCM) is a myocardial disease characterised by reduced ventricular compliance leading to diastolic dysfunction
  • Relatively uncommon, but is seen more frequently in cats than dogs
  • Early disease is usually asymptomatic with many cats only presenting once CHF or ATE have developed
  • Echocardiography is the diagnostic test of choice
  • Treatment focuses on supportive care and preventing or managing complications
  • Regular monitoring is essential for early detection and delaying the onset of complications
