Abstract

Coronary artery bypass graft (CABG) intervention, particularly anastomosis site intervention, is challenging for interventional cardiologists. A paclitaxel-eluting balloon catheter (SeQuent Please) is a recently-introduced device capable of delivering paclitaxel homogeneously into the targeted vessel wall. We herein report our experience with two cases. In the first case, coronary angiography showed significant stenosis at the site of anastomosis between the saphenous vein graft and the left anterior descending artery (LAD). In the second case, coronary angiography showed significant stenosis at the site of anastomosis between the left internal mammary artery and the LAD. We performed percutaneous intervention of these CABG anastomoses using paclitaxel-eluting balloon catheters, and obtained favorable angiographic and clinical outcomes.

Figure

• 

  Fig. 1 A: saphenous vein graft (SVG) angiography of the patient in Case 1 showed significant restenosis of anastomosis between the SVG and the distal left anterior descending artery (LAD), and significant stenosis in the distal LAD. B: post-intervention angiography showed minimal residual stenosis and blood flow of Thrombolysis in Myocardial Infarction (TIMI) grade III. C: four-month follow-up angiography showed no restenosis and blood flow of TIMI grade III.

  Fig. 2 A: left internal mammary artery (LIMA) angiography of patient in Case 2 showed significant stenosis of the mid left anterior descending artery (LAD) and anastomosis between the LIMA and the distal LAD. B: post-intervention angiography showed minimal residual stenosis and blood flow of Thrombolysis in Myocardial Infarction (TIMI) grade III. C: six-month follow-up angiography showed no restenosis and blood flow of TIMI grade III.
