Figure 1 Angiogram in the left anterior oblique projection with cranial angulation showing a restenosed stent in the proximal left anterior descending coronary artery (a). The distal part of the stent spanned a disease-free septal branch (Type B) and a diagonal branch (arrow) with ostial involvement (Type A). After treatment (b) a good angiographic result was obtained in the left anterior descending coronary artery (parent vessel); the septal branch remained patent but the diagonal branch became occluded (asterisk). This occlusion was clinically silent. The six-month angiogram (c) revealed an adequate angiographic result on the left anterior descending coronary artery and patency (reappearance) of the diagonal branch (arrow).
