Rocket-shape crossing technique: A combination of lead extraction and modified venoplasty for device upgrade with venous occlusion.

This case discusses an upgrade method to cardiac resynchronization therapy defibrillator for a 54 year old man with superior vena cava occlusion. Right ventricular lead extraction with modified venoplasty, Rocket shape Crossing Technique (RCT), was performed. In RCT the integration of the inflated balloon, halfway inside the laser sheath, and the laser sheath are advanced through the occlusion like a rocket shape crossing.
