-
A very rare congenital malformation characterised by a muscular appendix emerging from the left ventricular apex, rarely from the right ventricle or from both chambers, with clinical manifestations ranging from asymptomatic to life-threatening haemodynamic collapse. Often associated with other cardiac abnormalities but is mostly an isolated anomaly. It is mostly found in infants and children and occasionally as an incidental finding in adults. Two types are described: fibrous and muscular. The aetiology of congenital cardiac diverticulum is not known. Haemodynamic factors may play a role.
