Myocardial Ischemia caused by a coronary anomaly: left circumflex coronary artery arising from right sinus of valsalva

Mustafa Aydin et al. Tex Heart Inst J. 2004.

Abstract

We present the case of a patient in whom a previously undetected anomalous origin of the circumflex coronary artery caused myocardial ischemia and led to positive myocardial scintigraphic results. Subsequent coronary angiography showed that the left circumflex coronary artery arose from the right coronary ostium-an anomaly that has been associated with chest discomfort-without atherosclerotic lesions. The peripheral distribution of the left circumflex artery was normal. We describe the clinical and angiographic findings in our patient and discuss the relationship between coronary artery anomalies and ischemia.

Figures

None
Fig. 1 Tomographic scans during stress myocardial scintigraphy, in the short-axis (SAX), vertical long-axis (VLA), and horizontal long-axis (HLA) views, show perfusion defects in the mid and basal inferoseptal segments. The resting SAX, VLA, and HLA views show the perfusion after its return to normal.
None
Fig. 2 Coronary angiogram in the left anterior oblique view shows the circumflex coronary artery originating in the right coronary ostium and following a retroaortic course to its normal distribution area.
None
Fig. 3 Coronary angiogram in the right anterior oblique view shows the origin of the circumflex artery in the right sinus of Valsalva.
