Power Versus Temperature Controlled Ablation for Treatment of VT

Краткое описание

Ventricular Tachycardia (VT) is a life threatening heart rhythm that comes from the bottom chambers of the heart (the ventricles) and is a leading cause of sudden cardiac death. The majority of patients that are at risk of VT or suffer a cardiac arrest will have an Internal Cardiac Defibrillator (ICD) in situ to treat the abnormal heart rhythm. The ICD can deliver a painful shock to restore normal heart rhythm but importantly does not treat the underlying cause. Current treatment for the prevention of recurrent VT include catheter ablation (CA) or medication. Long-term results with global 12 month VT-free survival rates with CA are around 50%. The trial is to compare 2 different types of ablation catheter that are used to cauterise small areas of unhealthy tissue within the heart that are responsible for VT: Diamond Temp (DT) and Tacticath/Tactiflex (TF). Our hypothesis is that the DT ablation catheter will provide comparable efficacy and safety for the treatment of VT as the current industry gold standard (TF).
