    Iatrogenic left main coronary artery dissection is a rare but serious complication of PVC ablation, as demonstrated in a 60-year-old male patient.

  • 2

    The patient experienced acute anterior ST-segment elevation myocardial infarction following successful PVC ablation, necessitating emergency intervention.

  • 3

    Emergent coronary angiography revealed LMCA dissection and significant occlusion in the proximal LAD and ramus intermedius.

  • 4

    Intravascular ultrasound was crucial for assessing the extent of the dissection and guiding the revascularization strategy.

  • 5

    The case highlights the importance of a multidisciplinary Heart Team approach and the potential need for emergent CABG in severe cases.
