Percutaneous transluminal angioplasty of an anomalous left circumflex coronary artery arising from the right sinus of Valsalva.

This case report describes a patient with isolated stenosis of an anomalous circumflex artery with evidence of left ventricular lateral wall ischaemia. Percutaneous dilatation of this vessel was successfully performed and was facilitated by removing the tip of a standard guiding catheter permitting selective cannulation of the anomalous ostium. Similar innovations in the standard angioplasty technique may permit its application in other unusual anatomical situations.
