BIOTRONIK is releasing the world’s most powerful implantable cardioverter defibrillator (ICD) in the United States. The Inventra HF-T cardiac resynchronization therapy defibrillator (CRT-D) can deliver 42 joules of energy in one punch to jolt even difficult to manage hearts back into a proper rhythm.Most ICDs generate about 36 joules of energy, but larger hearts and those with a reduced ejection fraction may need a stronger shock to get their arrhythmia under control. The Inventra HF-T sends 42 joules immediately on the first shock, potentially able to save the lives of more patients on CRT-D therapy.The implant has a lifespan of up to 7.5 years, depending on usage, is compatible with full body scanning under certain conditions, and features monitoring algorithms designed to reduce the number of unnecessary shocks.
