Right coronary ostium agenesis with absence of the right coronary artery: a rare case of non-ST elevation coronary syndrome.

We present a case with right coronary ostium agenesis with anomalous origin of the right coronary artery from the left circumflex artery, which caused a non-ST elevation coronary syndrome. A review of the literature indicates this to be an extremely rare case.
