Introduction A 54-year-old man with superior vena cava occlusion was referred to our institution for an upgrade to cardiac resynchronization therapy defibrillator. Methods and results 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”. Conclusion Modified venoplasty can be useful during device upgrades in patients with venous occlusion.
