Novel double catheter technique in complex percutaneous coronary interventions

Abstract

We present a novel double catheter technique for successful complex intervention of a very old proximal left circumflex chronic total occlusion (>10 years old). Prior attempts of guide wire passage using bare wire alone, over-the wire balloon or microcatheter support techniques were unsuccessful.

Differences in primary indication for guide-extension catheter usage among the three target vessels

“…The buddy wire and anchoring balloon technique can be helpful in such situations [2,3]. The mother-in-child technique is another powerful method [4,5]. Applying a similar concept, the rapid-exchange guide extension catheter (GEC) has been evolving.…”
