The treatment of coronary chronic total occlusions (CTO) continues to solicit technical innovations. As success primarily depends on crossing the lesion with a wire, all aspects regarding tip shape retention, torque precision, and penetration ability of the guide-wire have greatly influenced new techniques and strategies. The world of interventional cardiology has to look carefully at these developments, and to use them accordingly to improve the success rate in ordinary percutaneous coronary interventions. We present a didactical case report of a CTO revascularization treated with a new 'dual core' technology guide-wire.
