Stenting of atherosclerotic stenoses in anomalously arising coronary arteries

This description of five cases brings to 37 the total number of reported patients in whom atherosclerotic lesions of anomalously arising coronary arteries have been stented. One-half of these have been right coronary arteries arising from the left sinus of Valsalva, followed in frequency by branches of single coronary arteries arising from solitary aortic ostia and left circumflex arteries arising from the right sinus of Valsalva or from the proximal portion of the right coronary artery. Proper guide-catheter selection, essential for successful stenting, usually matches the guide's configuration to the sinus of Valsalva from which the anomalous artery originates rather than to the final distribution of the coronary artery.
