| Figure 1: Chronic narrowing of the proximal left anterior descending coronary artery (LAD). A left anterior thoracotomy was performed to position a 1.5 to 2.25 mm rigid Delran occluder device on the proximal LAD. Figure 1-a: Schematic representation of the proximal LAD occluding device. Figure 1-b: Coronary angiogram performed at baseline following LAD instrumentation. Figure 1-c: Coronary angiogram showing severe proximal LAD stenosis 3 months following the implantation of the occluding device with few collaterals. |
