Iatrogenic fistula between the left anterior descending coronary artery and anterior interventricular vein following stenting.

We describe the case of a 61-year-old male who had a critical stenosis of the left anterior descending artery (LAD). Intravascular ultrasound demonstrated that the LAD was attached to a large anterior interventricular vein (AIV). After stenting, a fistula was noted between the LAD and AIV, which was successfully sealed by deploying a covered stent. To our knowledge, this is the first case of iatrogenic arteriovenous fistula between the LAD and AIV that occurred following stenting of the LAD.
