Figure 4: Serial Cine and IVUS Images Demonstrate the Use of Intravascular Ultrasound to Mark Structures of Interest During Peripheral Interventions.

Figure 4:

A–B) Angiographic views show a left SCA chronic total occlusion crossed by a guidewire and an ostial LIMA stenosis in a patient with angina pectoris and a prior LIMA bypass. The imaging window is positioned at the ostium of the LIMA and C) a short cine run is obtained to mark the LIMA ostium location using an Eagle Eye® Platinum ST Rx Digital IVUS Catheter, (Volvano Corporation, Rancho Cordova, CA). D) IVUS image of the LIMA ostium is shown. E) The LIMA ostium undergoes stent deployment. F) The SCA ostium is marked and the vessel distance is calculated using the 10 mm distance between the markers of the Eagle Eye® Platinum ST Rx Digital IVUS Catheter. IVUS images of the SCA ostium are observed G) pre intervention, and H) post intervention, confirming accurate geographic stent landing. I) Final cine findings are shown. SCA: Subclavian artery; LIMA: Left internal mammary artery; IVUS: Intravascular Ultrasound.
