Cases of Early, Aggressive In-Stent Restenosis in Left Main Double Kissing (DK) Crush Technique and Treatment Options
We present three recent cases at our institution that demonstrate early, aggressive in-stent restenosis (ISR) of double-kissing (DK) crush technique despite careful adherence to the technique and compliance of the patient. There are multiple percutaneous coronary intervention strategies for left main (LM) coronary artery bifurcation disease. The DK crush technique has gained popularity for the treatment of complex bifurcation lesions, including distal LM bifurcations.
