Double-Guide Catheter "Criss-Cross" Technique and Left Main Bifurcation Rotational Atherectomy.

ABSTRACT:

Background

Rotational atherectomy of severely calcified left main (LM) bifurcation lesions can be hazardous, especially when maintaining a protective guidewire in one branch is mandatory.

Case summary

An 82-year-old man underwent successful percutaneous coronary intervention of a calcified LM bifurcation using a double-guide catheter "criss-cross" technique to reduce periprocedural ischemia and iatrogenic dissection risk associated with a single larger catheter. Rotational atherectomy was safely performed on a tight proximo-ostial circumflex lesion while retaining a protective guidewire in the dissected left anterior descending artery.

Discussion

Although protective microcatheters have been described, bench studies show consistent microcatheter damage, risk of nonorga
