Insights
Ablating ventricular tachycardia from the great cardiac vein is challenging. Using a steerable sheath for deep engagement provides crucial backup force during ablation procedures.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Ventricular tachycardia (VT) ablation can be complex, especially when originating from the great cardiac vein.
- Achieving deep catheter engagement within the coronary venous system is a critical yet difficult step.
Abstract:
Ablation of ventricular tachycardia originating from the great cardiac vein involves the difficult step of deep engagement with an ablation catheter. The catheter and a steerable sheath (MobiCath, Biosense Webster, Diamond Bar, CA, USA) were advanced alternately only when the contact force vector was parallel to the coronary venous system. Deep engagement with a steerable sheath ensured a powerful backup force during ablation.
