title: Percutaneous transluminal coronary angioplasty of anomalous left circumflex coronary artery.
abstract: We present our experience of percutaneous transluminal coronary angioplasty in two patients with an anomalous left circumflex coronary artery with severe stenosis. In the first case, the anomalous vessel originated from the first portion of the right coronary artery, and in the second case it originated from the right sinus of Valsalva. Cannulating the anomalous vessel with the guiding catheter can be difficult. The right Judkins-type catheter, with a posteriorly directed tip, is the most appropriate catheter for cannulating the anomalous circumflex artery when the vessel originates from the first portion of the right coronary artery, and the left Amplatz-type 1 is most appropriate when the vessel originates from the right sinus of Valsalva.
