Abstract
Key Clinical MessageCatheter‐induced coronary dissection involving left main bifurcation is a rare complication during cardiac catheterization but can become lethal unless it is treated appropriately. Interventional cardiologists always have to pay attention to the risk of complications related to cardiac catheterization and prepare for determining the best bailout strategy for the situation.

Catheter-induced coronary artery dissection is an uncommon complication
We encountered a patient who suffered from catheter induced sudden lethal coronary dissection involving the left main (LM) bifurcation during CAG with a provocation study to detect coronary vasospasm
The mechanical injection of contrast media caused the marked enlargement of the dissected space, it was very fortunate that we could successfully introduce a guidewire through the intraluminal left circumflex (LCX) coronary artery
Summary
Catheter-induced coronary artery dissection is an uncommon complication. once critical coronary dissection occurs, the outcome can be fatal. The injection of contrast media suddenly caused spiral dissection, which rapidly spread out in the three directions of the proximal LMCA, left anterior descending (LAD) coronary artery, and left circumflex (LCX) coronary artery (Fig. 2A and B Arrows). Coronary flow in both LAD and LCX coronary arteries was interrupted by a coronary hematoma induced by enlargement of the dissected lumen (Fig. 2B Arrowheads).
