Figure 3 Pre-Procedure Angiogram From a 92-Year-Old Woman With Critical Aortic Stenosis in Preparation for Percutaneous Aortic Valve Implantation
This critically narrowed distal left main lesion (A) involves both the left anterior descending artery and circumflex ostia (arrow). To reduce the risk of closing one of the branch vessels, 2 stents were deployed simultaneously (arrow) using the double-barrel technique (B). The final angiographic result was excellent (C), but this lesion is at higher risk for restenosis, particularly at the circumflex ostium (arrow).
