Anomalous separate origin of the septal perforator coronary artery from the left sinus of valsalva.

The anomalous separate origin of the first septal perforator from the left sinus of Valsalva is described. Previously documented anomalous origins of the septal perforator include the left main coronary artery, the right coronary artery, the right sinus of Valsalva, a diagonal coronary artery, the circumflex coronary artery, and its obtuse marginal branch. We could not find any previous description of the septal perforator originating from a separate ostium in the left sinus of Valsalva.
