Coronary perforation Type III - Double guide catheters technique
The below schematic diagram shows the step-by-step double guide catheters technique.
(A) Balloon used in the angioplasty inflated at low pressure (4 ATM) at the perforation site. (B) Careful withdrawal of the first guide catheter outside the ostium and catheterization of the coronary ostium with the second guide catheter. (C and D) Advancement of the second guide catheter, crossing the perforation site with quick balloon deflation, allowing its passage. (E) Coated stent advancing over the second guide catheter. (F) Rapid deflation manoeuvre, balloon withdrawal and coated stent implantation at the perforation site.
