DFT and Your Patients

Inventra – Supercharged to Manage DFT

• More physicians are considering no DFT testing at implant, based on SIMPLE study.¹
• Multiple studies have identified factors that may impact defibrillation efficacy. Cumulatively, these factors could increase defibrillation threshold significantly.
• Up to 8% of patients have a high DFT ²

Risk Factors Decreasing Shock Efficacy

• Non-ischemic cardiomyopathy²
• Medication, e.g., amiodarone ³ or sildenafil⁴
• Patients with right-sided implantations⁵
• Large or tall patients with a greater body surface area⁶
• Younger and active patients ^{3, 7, 8}
• Patients with larger left-ventricular size or mass and very poor left ventricular ejection fraction ^{7, 8}

Extensive Options for Effective Defibrillation

• Various options to maximize DFT safety margins
• Multiple high-energy shocks - Up to 8 shocks per zone with 42 J max delivered energy
• Multiple waveforms - Biphasic (Voltage controlled) - Biphasic 2 (Time controlled)
• Multiple polarities - Normal - Reversed - Alternating – after first shock
• Multiple shock pathways - RV → CAN + SVC - RV → CAN - RV → SVC
