Treating left main stem perforation can be challenging due to the significant hemodynamic effect of one of the important steps, namely balloon tamponade.

We present a case of left main stem perforation that occurred during chronic total occlusion percutaneous coronary intervention which was treated with a covered stent across the left main stem into the left anterior descending artery.
