Iatrogenic Left Main Coronary Artery Dissection Due to Pin-hole Balloon Rupture: Not to Be Panicked…

Iatrogenic left main coronary artery (LMCA) dissection is a rare complication and may have devastating consequences if not immediately intervened. The management includes urgent revascularization mostly with percutaneous coronary intervention (PCI) with bail-out stenting and rarely requires coronary artery bypass graft (CABG) surgery. In clinically and hemodynamically stable patients, a conservative approach may be preferred. Here, we present a rare case of iatrogenic retrograde LMCA dissection due to pin-hole rupture of angioplasty balloon that was managed conservatively.
