Ebstein's anomaly presenting with the acute coronary syndrome-a rare combination.

Ebstein's anomaly is a relatively rare congenital heart disorder characterised by downward displacement of septal and posterior leaflets of the tricuspid valve into the right ventricle cavity. The usual presenting symptoms are cyanosis, right-sided heart failure and arrhythmia. Progressive heart failure or tachyarrhythmia may worsen cyanosis.
