Tips on coronary dissections

Seal off the entry point of the dissection with a stent. In aorto ostial dissection, flare up the ostial part of the stent. Do not pull out the catheter immediately on seeing a dissection. But while crossing the dissection, pull back the catheter slightly from the entry point.

Coronary dissection extending into the aorta:

Type I : Confined to the aortic sinus
Type II : Extending to less than or equal to 40 mm into the ascending aorta
Type III : Extending more than 40 mm into the ascending aorta
